Best Supercharger for 5.7 Hemi Challenger: Complete Performance Guide

The Dodge Challenger with its 5.7-liter Hemi V8 delivers respectable power straight from the factory, but many enthusiasts find themselves craving more. While the base R/T model produces around 370-375 horsepower, that’s just the beginning of what this legendary engine platform can achieve. Adding a supercharger to your 5.7 Hemi Challenger transforms it from a capable muscle car into a legitimate performance monster, often exceeding 550-600 horsepower with the right setup.

Choosing the best supercharger for your 5.7 Hemi Challenger isn’t just about buying the most expensive kit or the one with the flashiest marketing. It requires understanding your performance goals, budget constraints, driving habits, and willingness to modify supporting components. This comprehensive guide explores everything you need to know about supercharging your 5.7 Hemi Challenger, from technical fundamentals to specific product recommendations, installation considerations, and real-world performance expectations.

Whether you’re looking to dominate at the drag strip, enhance daily driving performance, or simply experience the thrill of forced induction, understanding the supercharger landscape will help you make an informed decision that aligns with your automotive aspirations.

Understanding the 5.7 Hemi Platform

Before diving into supercharger options, it’s essential to understand what makes the 5.7-liter Hemi engine special and how it responds to forced induction. Chrysler’s modern Hemi engine, reintroduced in 2003, features a hemispherical combustion chamber design that promotes efficient airflow and combustion. The 5.7L variant (345 cubic inches) has proven remarkably durable and modification-friendly over two decades of production.

The third-generation Hemi architecture used in Challengers from 2009 onward features several improvements over earlier versions, including variable valve timing (VVT) and an improved oiling system. These engines run a compression ratio of approximately 10.5:1, which sits in a sweet spot for supercharger applications—high enough for naturally aspirated efficiency but low enough to accept moderate boost without requiring extensive internal modifications.

Why the 5.7 Hemi Responds Well to Supercharging

The 5.7 Hemi’s iron block construction provides excellent strength and heat dissipation capabilities. Unlike some aluminum-block engines that struggle with thermal management under boost, the Hemi’s iron block can handle significant power increases with proper tuning. The forged steel crankshaft and powdered metal connecting rods found in most 5.7 Hemi engines are surprisingly robust, with many owners successfully running 550-600 horsepower on completely stock internals.

The engine’s efficient cylinder head design means it responds exceptionally well to increased air density. Where some engines show diminishing returns with forced induction, the Hemi’s hemispherical chamber design continues delivering power gains proportional to boost pressure, making every pound of boost translate into meaningful performance improvements.

How Superchargers Work: Technical Fundamentals

Understanding supercharger operation helps you make better decisions about which type suits your application. A supercharger is a mechanically-driven air compressor that forces more air into the engine’s combustion chambers than atmospheric pressure would naturally provide. This increased air density allows the engine to burn more fuel per cycle, directly translating to more power output.

Unlike naturally aspirated engines that rely on atmospheric pressure and piston vacuum to draw air into cylinders, supercharged engines actively compress intake air before it enters the combustion chamber. This compression process increases both air density and temperature, which is why most supercharger systems include intercoolers to reduce inlet air temperatures and prevent detonation.

The Mechanical Drive Advantage

Superchargers derive power from the engine’s crankshaft through a belt drive system. This mechanical connection means power delivery is instantaneous and linear throughout the RPM range—there’s no turbo lag or waiting for exhaust gases to spool a turbine. The moment you press the accelerator, you experience the full benefit of forced induction.

This direct drive does consume some engine power—typically 50-70 horsepower depending on boost levels—but the net gain far exceeds this parasitic loss. A properly sized supercharger producing 8 pounds of boost might consume 60 horsepower while adding 200+ horsepower, resulting in a net gain of 140+ horsepower to the wheels.

Boost, Airflow, and Power Production

Boost pressure, measured in pounds per square inch (PSI) above atmospheric pressure, directly correlates with power production. Each pound of boost typically adds approximately 6-8% more power to a naturally aspirated baseline. At 6 PSI, you might see a 40-45% power increase; at 9 PSI, you’re looking at 55-65% gains, assuming proper fueling and timing adjustments.

However, boost pressure alone doesn’t tell the complete story. Airflow volume matters equally. A supercharger producing 8 PSI while flowing 800 cubic feet per minute (CFM) will make significantly less power than one producing 8 PSI while flowing 1,000 CFM. This is why proper supercharger sizing for your specific engine displacement and RPM range is critical.

Types of Superchargers: Roots, Twin-Screw, and Centrifugal

Not all superchargers function identically. Three main supercharger designs dominate the automotive aftermarket, each with distinct characteristics, advantages, and trade-offs for Challenger applications.

Roots-Style Superchargers

Roots superchargers use two meshing lobed rotors that trap air between the rotors and the housing, then carry it from the inlet to the discharge port. These are the iconic “blower” superchargers you see protruding through the hood on classic hot rods and modern drag cars.

For 5.7 Hemi applications, Roots-style blowers deliver exceptional low-end torque and immediate throttle response. They produce strong boost at low RPM, making them ideal for street driving where most acceleration occurs between 2,000-4,500 RPM. The instant power delivery creates a dramatic, addictive driving experience.

However, Roots blowers are less thermally efficient than other designs. They compress air inside the intake manifold rather than before it, generating more heat. This requires larger, more efficient intercoolers to maintain safe inlet temperatures. They also tend to be less efficient at higher RPM, making them better suited for street performance than road racing or sustained high-speed driving.

Twin-Screw Superchargers

Twin-screw superchargers represent an evolution of Roots technology. Instead of trapping and carrying air, twin-screw rotors actually compress air internally through a screw-type mechanism similar to an air compressor. This internal compression makes them significantly more efficient than Roots blowers, generating less heat while producing similar boost levels.

The improved efficiency means twin-screw superchargers consume less parasitic horsepower from the engine while delivering more power to the wheels. They maintain strong performance across a broader RPM range than Roots blowers, making them excellent all-around performers for street and occasional track use.

Twin-screw superchargers typically produce a distinctive whine that many enthusiasts find appealing. They’re generally more expensive than Roots-style blowers but offer better fuel economy under part-throttle conditions and lower inlet air temperatures, which translates to more consistent performance and reduced detonation risk.

Centrifugal Superchargers

Centrifugal superchargers work similarly to turbochargers, using an impeller spinning at extremely high speeds (often 50,000+ RPM) to compress intake air. However, unlike turbos, they’re driven by a belt from the crankshaft rather than exhaust gases, eliminating lag while maintaining the compact packaging advantages of centrifugal compressors.

For 5.7 Hemi Challengers, centrifugal superchargers offer several compelling advantages. They’re typically the most efficient design, generating minimal heat while producing high boost pressures. Their compact size means easier installation, often fitting entirely within the stock engine bay without hood modifications. They’re also generally the most affordable option, making them popular for budget-conscious enthusiasts.

The trade-off is power delivery characteristics. Centrifugal superchargers produce boost progressively based on engine RPM—minimal boost at low RPM, building to maximum boost at high RPM. This creates a more gradual power curve similar to a naturally aspirated engine, just with significantly more top-end power. Some drivers find this preferable for drivability, while others miss the immediate low-end punch of positive-displacement designs.

Supercharger vs. Turbocharger: Making the Right Choice

Before committing to supercharging your 5.7 Hemi Challenger, you should understand how it compares to turbocharging—the other primary forced induction method. While this guide focuses on superchargers, understanding the alternatives helps validate your decision.

Power Delivery and Drivability

Superchargers provide immediate, linear power delivery from idle to redline. There’s no waiting for boost to build—the moment you open the throttle, forced induction is working. This makes supercharged cars feel incredibly responsive in daily driving, with strong acceleration from any RPM.

Turbochargers, conversely, rely on exhaust gas energy to spin a turbine. This creates turbo lag—a delay between throttle application and boost delivery. Modern turbo technology has minimized this lag, but it still exists, particularly with larger turbos capable of high boost pressures. Turbocharged cars often feel sluggish at low RPM, then suddenly surge with power once the turbo spools.

For a street-driven Challenger where most acceleration happens from stoplight to stoplight or during highway merging, superchargers generally provide a more satisfying driving experience. The instant throttle response makes the car feel more powerful in real-world driving conditions, even if peak horsepower numbers might be similar to a turbocharged setup.

Efficiency and Heat Management

Turbochargers are inherently more efficient than superchargers because they recover otherwise-wasted exhaust energy. A turbocharged engine doesn’t lose any crankshaft horsepower to drive the compressor, meaning more of the power gains reach the wheels. Turbochargers also typically run cooler, generating less heat in the intake charge.

Superchargers consume engine power to drive the compressor—typically 50-70 horsepower depending on boost levels and design efficiency. They also generate more heat, particularly Roots and twin-screw designs. However, modern supercharger systems with efficient intercoolers have largely mitigated heat concerns, maintaining safe inlet temperatures even during aggressive driving.

Installation Complexity and Cost

Supercharger kits are generally more straightforward to install than turbo systems. A complete bolt-on supercharger kit includes everything needed and typically installs in 20-30 hours with basic mechanical skills and tools. The installation process is reversible, maintaining better resale value and allowing you to return the car to stock if needed.

Turbo installations are more complex, often requiring custom exhaust fabrication, oil system modifications, and extensive tuning. While some bolt-on turbo kits exist, they’re less common for the 5.7 Hemi Challenger platform. Turbo installations also typically require more cutting and permanent modifications, making them harder to reverse.

Reliability and Maintenance

Properly installed superchargers are extremely reliable, often lasting 100,000+ miles with minimal maintenance beyond periodic belt replacements and oil changes (for systems requiring lubrication). The mechanical drive system is simple and robust.

Turbochargers operate in extremely harsh conditions—spinning at 100,000+ RPM while exposed to exhaust gases exceeding 1,500°F. While modern turbos are reliable, they have more failure points and require careful maintenance, including proper oil supply, cooldown procedures, and regular oil changes with high-quality synthetic oil.

For most Challenger owners seeking enhanced performance without extensive mechanical complexity, supercharging represents the better choice. The installation is simpler, the driving experience is superior for street use, and long-term reliability matches or exceeds turbocharged alternatives.

Top Supercharger Kits for 5.7 Hemi Challenger

After understanding supercharger fundamentals, let’s examine specific kits proven successful on the 5.7 Hemi Challenger platform. These recommendations balance performance, reliability, value, and installation ease.

Whipple W175AX 2.9L Twin-Screw Supercharger

For enthusiasts wanting maximum low-end torque and mid-range power, Whipple’s W175AX twin-screw system delivers face-melting performance with exceptional drivability. This positive-displacement supercharger produces strong boost from idle, creating instantaneous throttle response that makes the car feel like it has a completely different engine.

The W175AX (2.9-liter displacement) supercharger features Whipple’s advanced twin-screw rotor design, which internally compresses air for improved efficiency compared to traditional Roots blowers. At conservative boost levels (7-8 PSI), the system produces 550-600 horsepower while maintaining excellent fuel economy during part-throttle cruising. More aggressive pulley configurations can push power beyond 650 horsepower, though supporting modifications become necessary at those levels.

Whipple’s integrated air-to-water intercooler system is highly effective, using coolant circulation to remove heat from the intake charge. This maintains consistent inlet temperatures even during repeated acceleration runs, making the system ideal for drag racing applications. The intercooler reservoir holds two gallons of coolant mixture, providing excellent heat capacity.

The kit includes everything needed for installation: supercharger assembly, intercooler with pump and heat exchanger, throttle body, fuel injectors, fuel rails, mounting hardware, and all necessary tubing and wiring. Installation requires 25-35 hours for most mechanics, slightly more complex than centrifugal systems due to the larger supercharger and intercooler components.

One consideration with Whipple systems is sound. The twin-screw design produces a distinctive, prominent whine that some owners love and others find excessive for daily driving. It’s noticeably louder than centrifugal superchargers, though many enthusiasts consider this an attractive feature rather than a drawback.

Whipple kits typically retail for $7,500-$8,500, making them premium-priced. However, the power delivery characteristics are addictive for street driving, and the system’s efficiency means better fuel economy than many alternatives. If low-end torque and instant throttle response are priorities, the Whipple system deserves serious consideration despite its higher price point.

Magnuson TVS2300 Heartbeat Supercharger

Magnuson’s TVS2300 system offers Roots-style performance with modern efficiency, utilizing Eaton’s advanced TVS (Twin Vortices Series) technology. The TVS rotor design incorporates twisted lobes that trap and move air more efficiently than traditional Roots designs, reducing heat generation while improving volumetric efficiency.

The 2,300cc displacement supercharger produces 7-9 PSI of boost, resulting in 500-550 horsepower depending on supporting modifications and tuning. The system delivers strong low-end torque similar to traditional Roots blowers but with significantly better thermal efficiency. The integrated air-to-water intercooler maintains safe inlet temperatures during aggressive driving.

Installation is comprehensive, with the kit including the supercharger assembly, intercooler system with pump and heat exchanger, new intake manifold, throttle body, fuel injectors, all mounting hardware, and detailed instructions. The installation requires 30-40 hours due to the complete intake manifold replacement, making it the most labor-intensive option discussed here.

The Magnuson system produces a deep, throaty supercharger whine that many owners find appealing. It’s not as shrill as twin-screw designs but more prominent than centrifugal systems. The instant boost production creates addictive low-end power, making the Challenger feel significantly more powerful in everyday driving situations.

One unique advantage of the Magnuson system is its appearance. The large supercharger sits prominently atop the engine, visible through the engine bay, giving your Challenger the classic blown-engine aesthetic without requiring hood modifications. For owners who value underhood appearance alongside performance, this visual impact adds appeal.

Pricing typically ranges from $6,500-$7,500, positioning it between ProCharger and Whipple systems. The combination of strong low-end power, modern efficiency, and distinctive appearance makes it an excellent choice for street-oriented builds where daily drivability matters.

Edelbrock E-Force Stage 1 Street Supercharger

Edelbrock’s E-Force system provides excellent value for budget-conscious enthusiasts seeking proven performance without premium pricing. The Stage 1 kit uses an Eaton TVS supercharger similar to the Magnuson system but includes different mounting solutions and component specifications that reduce overall cost.

The kit produces 6-7 PSI of boost on pump gas, delivering 475-510 horsepower to the crank.

Factors to Consider When Choosing a Supercharger

Selecting the right supercharger requires evaluating multiple factors beyond peak horsepower numbers. Your driving style, performance goals, budget, and willingness to perform supporting modifications all influence which system best suits your needs.

Power Goals and Driving Style

Your intended power level significantly impacts supercharger selection. If you’re targeting 500-550 horsepower for enhanced street performance, virtually any quality supercharger system will excel. However, if you’re chasing 600+ horsepower, you’ll need to consider systems with higher flow capacity and plan for supporting modifications.

Consider how you drive your Challenger. If most driving involves city streets, highway commuting, and occasional spirited acceleration, a positive-displacement supercharger (twin-screw or Roots-style) provides the most satisfying experience. The instant boost production makes every acceleration feel powerful, even brief throttle applications.

For track use, road racing, or sustained high-speed driving, centrifugal superchargers often prove superior. Their efficiency at high RPM, minimal heat generation, and progressive power delivery make them ideal for extended performance driving. They also leave more power available for supporting systems like cooling fans and accessories during demanding track sessions.

Budget Considerations

Supercharger costs extend beyond the kit itself. A realistic budget includes installation labor (unless you’re installing yourself), tuning, and supporting modifications that may become necessary. Here’s a realistic cost breakdown:

Budget Supercharger Build ($7,000-$9,000 total)

  • Supercharger kit: $5,200-$5,800
  • Installation (if paying shop): $1,200-$1,800
  • Dyno tuning: $500-$700
  • Upgraded spark plugs: $50-$80
  • Fuel system enhancement (if needed): minimal to $300

Mid-Range Supercharger Build ($9,000-$12,000 total)

  • Supercharger kit: $5,800-$7,000
  • Installation: $1,500-$2,200
  • Dyno tuning: $600-$900
  • Upgraded spark plugs: $50-$80
  • Fuel pump upgrade: $300-$500
  • Upgraded clutch (manual transmission): $800-$1,200

Premium Supercharger Build ($12,000-$16,000+ total)

  • Premium supercharger kit: $7,500-$8,500
  • Professional installation: $2,000-$3,000
  • Comprehensive dyno tuning: $800-$1,200
  • Complete fuel system upgrade: $800-$1,500
  • Transmission upgrades: $1,500-$3,000
  • Upgraded clutch: $1,000-$1,500
  • Upgraded wheels/tires for traction: $1,500-$2,500

These numbers assume you’re starting with a mechanically sound Challenger. If your car needs deferred maintenance, factor in those costs first. Installing a supercharger on an engine with worn components is asking for expensive failures.

Warranty and Reliability Concerns

Supercharger installation typically voids factory powertrain warranties, though specific warranty language varies. Some dealers are more modification-friendly than others, but you should assume warranty coverage will be lost for engine and transmission components once you modify the car.

Third-party extended warranties similarly exclude coverage for modified vehicles. If your Challenger is new with significant remaining factory warranty, you might consider waiting until warranty expiration before supercharging, unless you’re comfortable assuming all repair costs yourself.

Regarding reliability, quality supercharger systems are remarkably durable when properly installed and maintained. The supercharger itself typically outlasts the engine if supplied with clean oil (for systems requiring lubrication). The greater reliability concern involves supporting components—transmissions, rear differentials, axles, and clutches—which experience significantly increased stress under boosted power.

Installation Complexity

Some supercharger kits are genuinely bolt-on, requiring no permanent modifications or custom fabrication. Others involve more complex installation with extensive disassembly and modification. Assess your mechanical skills honestly before deciding whether to install yourself or pay a professional.

Centrifugal supercharger kits like ProCharger are generally the most straightforward to install. The compact supercharger mounts to a bracket assembly, the intercooler fits in front of the radiator, and plumbing connections are clearly defined. With basic hand tools and mechanical experience, capable DIYers can complete installation in a long weekend.

Positive-displacement kits (Roots, twin-screw) are more complex, requiring complete removal of the stock intake manifold and installation of the supercharger assembly in its place. This involves disconnecting fuel lines, coolant lines, throttle linkages, and extensive wiring. Professional installation makes more sense unless you have significant mechanical experience.

Tuning is another consideration. Some kits include handheld tuners or pre-programmed calibrations that allow the car to run safely immediately after installation. Others require professional dyno tuning before the first startup. Factor in tuning requirements and costs when evaluating kits.

Supporting Modifications for Supercharged 5.7 Hemi Challengers

Installing a supercharger represents just the foundation of a complete performance build. Supporting modifications maximize power, ensure reliability, and optimize the driving experience. Some modifications are essential for safe operation; others are recommended for optimal performance; still others are optional enhancements for specific goals.

Fuel System Upgrades

The stock 5.7 Hemi fuel system handles naturally aspirated power requirements perfectly but may struggle to supply adequate fuel for supercharged applications. At 550+ horsepower, fuel demand increases 40-50% beyond stock. Insufficient fuel supply causes lean air/fuel ratios, which lead to catastrophic engine damage through detonation and excessive combustion temperatures.

Most supercharger kits include upgraded fuel injectors sized appropriately for the power level. However, the fuel pump may need upgrading depending on target boost levels. At 6-7 PSI on a conservative tune, the stock fuel pump typically suffices. Beyond 8 PSI or when targeting 575+ horsepower, an upgraded fuel pump becomes essential.

Several high-flow fuel pump options exist for 5.7 Hemi Challengers, typically flowing 340-400 liters per hour compared to the stock pump’s 275 LPH capacity. The increased flow ensures adequate fuel pressure across the entire RPM range, even at wide-open throttle. Installation involves dropping the fuel tank, making it a good opportunity to install a new fuel filter simultaneously.

Some builders also upgrade fuel lines and fuel rails for maximum flow capacity, though this becomes necessary only at extreme power levels (650+ horsepower). For most street-driven supercharged Challengers making 500-600 horsepower, upgraded injectors and possibly an upgraded pump provide adequate fuel system capacity.

Ignition System Enhancements

Forced induction increases cylinder pressure significantly, making it harder for spark plugs to ignite the air/fuel mixture. Upgrading to colder spark plugs with proper heat range prevents fouling and ensures reliable ignition under boost. Most supercharger manufacturers recommend specific spark plugs and gap specifications for their systems.

Typical recommendations involve running spark plugs one to two heat ranges colder than stock, with reduced gap (typically 0.035″ instead of the stock 0.040-0.045″). The colder heat range prevents pre-ignition under boost, while the tighter gap ensures consistent spark even against increased cylinder pressure.

Some builders also upgrade ignition coils for enhanced spark energy, though this is generally unnecessary with quality modern coil-on-plug systems. The stock ignition system typically provides adequate spark energy for supercharged applications up to 600 horsepower when using proper spark plugs.

Cooling System Improvements

Superchargers generate additional heat through several mechanisms: increased combustion energy, air compression heating, and the mechanical energy consumed driving the supercharger itself. Maintaining proper operating temperatures becomes critical for reliability and performance.

Most supercharger kits include intercoolers to reduce intake air temperature, but engine coolant temperatures may still increase during aggressive driving. Upgrading to a higher-capacity radiator helps manage this additional heat load. High-flow water pumps improve coolant circulation, further enhancing cooling capacity.

For air-to-water intercooler systems (used by twin-screw and some Roots-style blowers), consider upgrading the intercooler heat exchanger and increasing intercooler reservoir capacity. Some builders install supplemental electric pumps for improved intercooler coolant circulation, maintaining lower inlet temperatures during repeated acceleration runs.

Oil temperatures also increase under boost. Installing an oil cooler helps maintain proper oil temperatures, particularly during track use or extended performance driving. Proper oil temperatures extend engine life and prevent oil breakdown that could lead to bearing damage.

Transmission and Driveline Upgrades

The stock transmission and rear differential in 5.7 Hemi Challengers handle factory power without issue, but forced induction can overwhelm these components quickly. Transmission failures are among the most common issues in supercharged Challengers, particularly automatic transmissions subjected to aggressive launches.

For automatic transmissions, a performance torque converter with higher stall speed helps manage the increased torque load while improving acceleration. Upgraded clutch packs and valve body modifications increase holding capacity, preventing slippage under boost. Many builders install transmission coolers to manage the increased heat generated by higher power levels.

Manual transmission Challengers need upgraded clutches to handle increased torque without slippage. Stock clutches typically slip when power exceeds 450-500 wheel horsepower. Performance clutches rated for 600+ lb-ft of torque ensure reliable power transfer without slippage, though they may compromise pedal feel and engagement smoothness.

The rear differential may need attention depending on driving style and power levels. Drag racing launches with sticky tires at 550+ horsepower can break stock axles, differential gears, or even the differential housing itself. Upgraded axles, limited-slip differential rebuilds, and differential reinforcement become necessary for serious drag racing applications.

Traction and Suspension Considerations

Power means nothing without traction. The stock 245-width tires on many 5.7 Hemi Challengers struggle to handle even stock power during aggressive launches, let alone an additional 150-200 horsepower from a supercharger. Upgrading to wider, stickier tires transforms launching ability and overall traction.

Many owners upgrade to 275 or 285-width rear tires, or even wider if running square setups. Drag radials or performance summer tires provide significantly better traction than all-season rubber. For maximum straight-line performance, Mickey Thompson or Nitto drag radials deliver incredible launches, though they compromise wet-weather traction and treadwear.

Suspension modifications help manage weight transfer during launches and improve handling. Adjustable shocks and struts, upgraded sway bars, and performance bushings tighten handling while maintaining reasonable ride quality. For drag racing, specific suspension modifications like adjustable coilovers or even drag-specific suspension setups optimize weight transfer for maximum traction off the line.

Installation Process: What to Expect

Understanding the installation process helps you prepare adequately, whether tackling the work yourself or supervising a professional installation. While specific steps vary by supercharger type and kit, the general process follows similar patterns.

Pre-Installation Preparation

Before beginning installation, thoroughly inspect your engine and address any existing issues. A supercharger amplifies problems—fixing them before installation prevents catastrophic failures. Check for oil leaks, coolant leaks, worn belts, weak batteries, and marginal spark plugs. Replace anything questionable now rather than discovering problems after supercharger installation.

Gather all necessary tools before starting. Quality socket sets, torque wrenches, jack stands, oil drain pans, and safety equipment are essential. Many supercharger installations require removing the front bumper for intercooler installation, so have a safe place to store removed components.

Read through the entire installation manual before starting. Understanding the complete process helps prevent mistakes and allows you to mentally prepare for complex steps. Note any special procedures, torque specifications, or assembly sequences that require particular attention.

Typical Installation Steps

Most supercharger installations follow this general sequence:

Phase 1: Disassembly (4-8 hours) Remove the stock intake system, including air box, intake tube, and throttle body. Disconnect battery cables, fuel lines, and any electrical connections that will interfere with installation. For positive-displacement superchargers, remove the entire stock intake manifold—a major undertaking requiring careful disconnection of fuel injectors, coolant lines, vacuum lines, and various sensors.

Remove front bumper assembly for intercooler installation. This typically involves removing 15-25 fasteners and disconnecting fog light wiring. The process is straightforward but time-consuming.

Phase 2: Component Installation (6-12 hours) Install the supercharger mounting brackets and assemble the supercharger unit. For centrifugal systems, this involves bolting the bracket assembly to specific engine mounting points, then installing the supercharger to the bracket. For positive-displacement systems, install the complete supercharger intake manifold assembly with new gaskets, transferring fuel rails, injectors, and sensors from the stock manifold.

Install the intercooler assembly in front of the radiator. This requires careful fitment to ensure adequate airflow while maintaining proper clearances. Plumb coolant lines for air-to-water systems or route charge piping for air-to-air systems.

Install belt drive components, including tensioner pulleys and the supercharger drive belt. Proper belt tension is critical—too loose causes slippage and heat, too tight causes bearing wear. Follow manufacturer specifications carefully.

Phase 3: Final Assembly and Connections (4-8 hours) Reinstall or install new intake tubing, connecting the supercharger to the throttle body and intercooler. Install bypass valves and blow-off valves per manufacturer specifications. These components protect the supercharger during deceleration and light throttle operation.

For systems requiring lubrication, plumb the oil feed and return lines. The feed line typically taps into the engine oil system at a gallery plug, while the return line drains to the oil pan. Proper routing prevents kinking and ensures adequate oil supply to the supercharger bearings.

Connect all electrical components, including sensors, the tuning module (if included), and any gauges. Double-check all electrical connections for proper seating and routing that prevents chafing against hot or moving components.

Reinstall the front bumper assembly and any other removed components. Fill all fluids—engine oil, coolant, intercooler coolant (if applicable)—and verify proper levels.

Phase 4: Initial Startup and Verification (1-2 hours) Before starting the engine, perform a thorough inspection of all connections. Verify belt tension, check for any tools or hardware left in the engine bay, and ensure all electrical connections are seated properly.

Initial startup should be brief—just 30-60 seconds—to verify the engine runs and check for obvious leaks. Shut down and inspect for oil, coolant, or fuel leaks. After addressing any issues, perform an extended idle period while monitoring coolant and oil temperatures, belt operation, and any unusual noises.

Take the car for a gentle test drive, gradually increasing throttle input while monitoring engine behavior. Pay attention to any unusual sounds, vibrations, or warning lights. Schedule dyno tuning as soon as practical to optimize the fuel and ignition maps for your specific setup.

Professional vs. DIY Installation

Professional installation ensures proper setup and provides peace of mind, particularly for your first supercharger installation. Experienced shops have installed dozens or hundreds of these systems, understanding every nuance and potential problem. They have specialized tools, lifts, and diagnostic equipment that simplify the process.

Professional installation typically costs $1,200-$3,000 depending on shop rates, kit complexity, and whether they’re performing tuning. While expensive, you’re paying for expertise that prevents costly mistakes. Many shops also warranty their installation work, protecting you against installation-related failures.

DIY installation saves money and provides satisfaction from completing the work yourself. If you have significant mechanical experience, necessary tools, and a well-equipped workspace, installing a supercharger is challenging but achievable. Allow significantly more time than manufacturer estimates suggest—what professionals complete in 20 hours may take DIYers 30-40 hours spread across multiple weekends.

Tuning Your Supercharged 5.7 Hemi

Proper tuning represents the difference between a reliable supercharger system that delivers consistent performance for years and one that fails catastrophically after a few thousand miles. Professional dyno tuning optimizes your air/fuel ratios, ignition timing, and boost levels for maximum power while maintaining safe operating parameters.

Why Professional Tuning Matters

Factory engine calibrations are designed for naturally aspirated operation with conservative safety margins. Simply bolting on a supercharger without recalibrating the engine computer produces a dangerously lean air/fuel mixture—the engine receives 40-50% more air without corresponding fuel increases. This lean condition causes detonation, excessive combustion temperatures, and rapid engine failure.

Professional tuners use dynamometers to measure actual engine performance while monitoring critical parameters: air/fuel ratios, ignition timing, boost pressure, coolant temperature, and exhaust gas temperature. They adjust fuel delivery and ignition timing throughout the entire RPM range, creating custom calibrations optimized for your specific combination of supercharger, fuel quality, and power goals.

Beyond safe operation, proper tuning extracts maximum performance from your supercharger investment. The difference between generic “safe” calibrations and optimized custom tuning can be 30-50 horsepower plus improved throttle response and fuel economy. If you’re spending $6,000-$8,000 on a supercharger system, spending an additional $500-$900 on proper tuning maximizes your investment.

What Happens During Dyno Tuning

A comprehensive dyno tuning session typically lasts 3-4 hours. The tuner begins by installing wideband oxygen sensors to accurately measure air/fuel ratios across all cylinders. They connect diagnostic equipment to monitor real-time engine parameters while the car operates on the dyno.

Initial pulls are performed at modest throttle openings and RPM ranges to establish baseline values and verify safe operation. The tuner gradually increases throttle and RPM while monitoring for detonation, excessive temperatures, or other concerning parameters. They adjust fuel and timing maps cell by cell, optimizing each portion of the operating range.

Boost levels are carefully managed during initial tuning. Most tuners start with conservative boost (4-6 PSI) while establishing safe air/fuel ratios and ignition timing. Once the engine runs cleanly at lower boost, they gradually increase boost pressure while continuing to monitor and adjust parameters.

Final tuning focuses on wide-open throttle performance, where maximum power is produced. The tuner makes multiple full-throttle pulls while fine-tuning fuel delivery and ignition advance for peak power without detonation. They verify air/fuel ratios remain in safe ranges (typically 11.5:1 to 12.5:1 at wide-open throttle under boost) and that ignition timing doesn’t cause knock or pre-ignition.

The completed calibration is saved to your engine computer, permanently storing all optimizations. Quality tuners provide dyno charts showing horsepower and torque curves, along with data logs from the session. Keep these records for future reference—they’re invaluable if you make additional modifications or experience problems.

Choosing Octane and Fuel Quality

Fuel octane rating directly impacts how much boost and ignition timing your engine can safely handle. Octane measures fuel’s resistance to detonation—higher octane fuels withstand more cylinder pressure and heat before spontaneously igniting. For supercharged applications, fuel quality makes a substantial difference in achievable power and reliability.

Most supercharger kits for 5.7 Hemi Challengers are designed around 91-93 octane pump gas, which is readily available throughout most of the United States. At 6-8 PSI boost with proper tuning, 91-93 octane prevents detonation while delivering 500-575 horsepower. Conservative boost levels on quality pump gas create a reliable, street-friendly combination.

For maximum power, race gas or E85 ethanol fuel allows significantly more aggressive tuning. E85’s octane rating equivalent of 105+ enables boost pressures of 10-12 PSI or higher, producing 650+ horsepower from the stock 5.7 Hemi engine. However, E85 requires extensive fuel system modifications—larger injectors, high-flow fuel pumps, and complete recalibration—plus careful attention to cold-start performance and fuel availability.

Race gas (100-110 octane) similarly allows aggressive boost and timing, though at $8-$15 per gallon, it’s expensive for street driving. Most owners reserve race gas for track days or drag racing, running pump gas for daily driving.

Never use regular unleaded (87 octane) in a supercharged engine, regardless of boost levels. The low octane rating cannot withstand forced induction’s increased cylinder pressures, virtually guaranteeing detonation and engine damage. Using proper fuel is non-negotiable for forced induction reliability.

Real-World Performance Expectations

Understanding realistic performance expectations helps you set appropriate goals and budget accurately. While marketing materials often tout impressive numbers, actual results depend on numerous factors: supporting modifications, tuning quality, environmental conditions, and measurement methods.

Horsepower and Torque Gains

A properly installed and tuned supercharger typically increases power by 170-220 horsepower and 140-180 lb-ft of torque compared to a stock 5.7 Hemi Challenger R/T. This transforms the car’s performance dramatically, changing how it feels in every driving situation from highway merging to full-throttle acceleration.

Starting from a stock baseline of approximately 370-375 crank horsepower, conservative supercharger setups (6-7 PSI) produce 520-560 horsepower. More aggressive tunes at 8-9 PSI push power to 575-625 horsepower. These numbers represent crank horsepower—actual wheel horsepower is approximately 15% lower due to driveline losses.

Torque increases are similarly impressive. Stock 5.7 Hemi torque output of 395-410 lb-ft grows to 520-580 lb-ft with supercharging. This massive torque increase is particularly noticeable during acceleration—the car pulls harder from any RPM, making every throttle application feel forceful and immediate.

Peak power typically occurs between 5,800-6,200 RPM, slightly higher than stock but still within the engine’s comfortable operating range. Torque peaks earlier, usually around 4,200-4,800 RPM, creating a broad, flat torque curve that makes the car feel incredibly strong throughout the RPM range.

Acceleration Performance

Supercharging transforms your Challenger’s acceleration capability across all metrics. Quarter-mile times improve by 1.5-2.5 seconds compared to stock, depending on driver skill, track conditions, and tire setup. A stock 5.7 Hemi Challenger R/T typically runs 13.8-14.2 seconds at 98-102 MPH in the quarter mile. With a supercharger and minor supporting modifications, times drop into the high 11-second to mid-12-second range at 115-120 MPH.

0-60 MPH times improve from approximately 5.1-5.3 seconds stock to 3.8-4.3 seconds with a supercharger, again depending heavily on tire setup and launch technique. The limiting factor becomes traction—launching aggressively with 550+ horsepower on street tires produces impressive tire smoke but slower times than disciplined launches with controlled wheelspin.

60-100 MPH roll-on acceleration, where traction is less critical, showcases the supercharger’s power advantage even more dramatically. Stock Challengers require 9-10 seconds for this sprint; supercharged examples complete it in 5.5-6.5 seconds. This massive reduction in roll-on times makes highway passing effortless and transforms highway driving character completely.

Daily Driving Impact

Beyond raw acceleration numbers, supercharging changes the daily driving experience fundamentally. The increased power and torque are available constantly, not just during full-throttle acceleration. Merging onto highways, passing slower traffic, and accelerating from stoplights all feel dramatically more effortless.

Fuel economy does suffer, though perhaps less than expected. During gentle cruising at steady speeds, fuel consumption increases only 1-2 MPG compared to stock, as the engine isn’t working significantly harder. However, it’s psychologically difficult to resist using the additional power frequently, and most owners report real-world fuel economy decreasing 3-4 MPG due to more aggressive driving habits.

The supercharger sound adds character to the driving experience. Centrifugal systems produce subtle whistling under boost, audible from inside the cabin but not overwhelming. Twin-screw and Roots-style blowers create more prominent whine that many enthusiasts find addictive. Under normal cruising conditions, noise levels remain civilized—the supercharger only makes itself heard during moderate to hard acceleration.

Reliability remains excellent with proper installation and maintenance. Many owners accumulate 50,000-100,000+ miles on supercharged 5.7 Hemi Challengers without significant issues. The key is following maintenance schedules, using quality fluids, and avoiding abusive driving before the engine reaches operating temperature.

Maintenance and Long-Term Ownership

Supercharged engines require slightly more attention than naturally aspirated powerplants, though maintenance isn’t excessively burdensome. Following proper maintenance procedures ensures years of reliable forced-induction performance without expensive failures.

Routine Maintenance Requirements

Oil changes become even more critical with forced induction. The increased combustion temperatures and cylinder pressures create harsher operating conditions that stress oil more than naturally aspirated operation. Most experts recommend shortening oil change intervals to 3,000-4,000 miles with supercharged engines, even using synthetic oil.

Use high-quality full-synthetic oil meeting Chrysler MS-6395 specifications. The enhanced thermal and oxidative stability of synthetic oil protects bearings and internal components better than conventional oil under boost. Many owners use 5W-30 or 0W-40 weight oils designed for high-performance applications.

For systems requiring supercharger lubrication (primarily centrifugal designs), follow manufacturer recommendations for supercharger oil changes. ProCharger systems typically require oil changes every 12,000 miles using their specified synthetic oil. This simple maintenance prevents bearing wear that could cause expensive supercharger failures.

Spark plug inspection and replacement becomes more frequent—every 20,000-30,000 miles rather than the stock 60,000-100,000 mile intervals. Forced induction is harder on spark plugs, and failing to replace worn plugs risks misfires that can damage catalytic converters or even cause engine damage from detonation.

Belt Inspection and Replacement

The supercharger drive belt experiences tremendous loads—tens of thousands of pounds of tension during high-boost operation. Inspect the belt every 5,000 miles for signs of wear, cracking, fraying, or glazing. Replace any belt showing damage immediately to prevent failure at wide-open throttle, which could cause supercharger damage.

Most supercharger systems use multi-rib serpentine belts similar to standard accessory drive belts. These typically last 20,000-40,000 miles before requiring replacement, though lifespan varies based on driving style and environmental conditions. Keep a spare belt in your garage—belt replacement is straightforward and prevents being stranded by a failed belt.

Belt tension also requires periodic verification. Belts stretch slightly over time, and incorrect tension causes slippage (too loose) or bearing wear (too tight). Check tension every 10,000 miles using the methodology specified in your supercharger kit instructions.

Cooling System Maintenance

Supercharged engines work harder, generating more heat that stresses the cooling system. Maintain the cooling system meticulously to prevent overheating that could cause engine damage or gasket failures.

Flush and replace coolant every 30,000 miles or 3 years using OEM-spec coolant. Inspect all coolant hoses for cracks, bulges, or soft spots that indicate deterioration. Replace any questionable hoses before they fail. Pay particular attention to heater hoses and radiator hoses, which experience increased temperatures with forced induction.

For air-to-water intercooler systems, maintain the intercooler coolant circuit separately. These systems should use distilled water mixed with water wetter or specific intercooler coolant additives rather than engine coolant. Flush and refill the intercooler system annually to prevent contamination that could reduce cooling efficiency.

Monitor coolant temperatures during driving, particularly in traffic or on hot days. If temperatures consistently exceed 210-220°F, investigate cooling system capacity. Adding a higher-capacity radiator or auxiliary electric fans may be necessary for adequate cooling during demanding driving conditions.

Monitoring for Problems

Pay attention to how your supercharged Challenger behaves during normal driving. Changes in performance, unusual sounds, or different behavior may indicate developing problems. Addressing issues early prevents minor problems from becoming catastrophic failures.

Listen for changes in supercharger sound. Grinding, scraping, or roughness suggests bearing wear or internal damage requiring immediate attention. Reduced boost pressure or sluggish performance may indicate belt slippage, boost leaks, or failing components.

Monitor your fuel trims and knock sensors using diagnostic tools. Increasing positive fuel trims may indicate fuel system problems—possibly a failing fuel pump or clogged fuel filter. Knock sensor activity suggests detonation that could damage your engine if not addressed immediately.

Inspect for oil leaks regularly, particularly around the supercharger oil feed and return lines (if applicable). Small leaks can escalate quickly, and oil contamination of the belt or pulleys could cause belt failure. Similarly, check for boost leaks at all intercooler connections and charge piping—even small leaks reduce performance and affect tuning.

Before supercharging your Challenger, understand the legal and warranty implications. Regulations vary by location, and manufacturers have specific policies regarding modified vehicles.

Emissions Compliance

Federal law requires vehicles to maintain their original emissions equipment and capabilities. Removing catalytic converters, disabling emissions controls, or installing systems that cause vehicles to exceed allowable emissions levels violates federal regulations and may violate state laws.

Most quality supercharger systems maintain all factory emissions equipment and include CARB (California Air Resources Board) exemption orders demonstrating legal compliance. Look for systems with CARB E.O. numbers, which certify them as legal for street use in California—and by extension, legal throughout the United States.

California and several states that follow California emissions regulations have particularly strict requirements. Only install supercharger systems specifically certified for your vehicle’s year, make, and model. Installing non-CARB-compliant systems risks failing emissions testing, receiving citations during vehicle inspections, and being unable to register your vehicle.

Factory Warranty Impact

Installing aftermarket forced induction typically voids factory powertrain warranties for affected components. While some dealers are modification-friendly, most will deny warranty claims on engines, transmissions, or related components if they discover aftermarket forced induction.

The Magnuson-Moss Warranty Act provides some protection—dealers must prove modifications caused specific failures rather than simply denying all claims on modified vehicles. However, proving a supercharger didn’t contribute to an engine or transmission failure is often impossible, leaving you responsible for repair costs.

Some strategies minimize warranty risk. Installing the supercharger after factory warranty expiration eliminates concerns entirely. Purchasing third-party extended warranties before modification (some cover modified vehicles if disclosed during purchase) provides alternative protection. Maintaining meticulous maintenance records demonstrates responsible ownership if warranty claims arise.

If your Challenger is new with significant warranty remaining, carefully consider whether immediately voiding that coverage makes financial sense. Waiting 2-3 years until warranty expiration, then supercharging, may be the prudent path.

Insurance Implications

Inform your insurance company about modifications to ensure adequate coverage. While premium increases are typically modest (often 10-20% for declared modifications), failing to disclose modifications can void coverage if claims arise.

Some insurance companies specialize in modified vehicles, offering agreed-value policies that protect your investment more comprehensively than standard policies. These policies cost more but provide peace of mind if your modified Challenger is damaged or stolen—they’ll compensate you for the vehicle’s actual value including modifications, not just base vehicle value.

Frequently Asked Questions About Supercharging 5.7 Hemi Challengers

How much horsepower does a supercharger add to a 5.7 Hemi?

A quality supercharger system adds approximately 170-220 horsepower to a 5.7 Hemi Challenger, taking output from the stock 370-375 horsepower to 540-595 horsepower depending on boost levels and supporting modifications. Conservative setups at 6-7 PSI produce 520-560 horsepower, while more aggressive tunes at 8-9 PSI push toward 575-625 horsepower.

Will a supercharger damage my engine?

Properly installed and tuned superchargers do not damage engines. The 5.7 Hemi’s robust construction—iron block, forged steel crankshaft, and strong connecting rods—handles 550-600 horsepower reliably on stock internals. The critical factors are professional installation, proper tuning with safe air/fuel ratios, using appropriate octane fuel, and maintaining proper maintenance schedules. Reliability issues arise from poor installation, inadequate tuning, or abusive driving rather than supercharging itself.

Can I install a supercharger myself?

Experienced DIY mechanics with proper tools and workspace can install supercharger kits themselves, though professional installation ensures optimal results. Centrifugal systems are more DIY-friendly, requiring 20-30 hours for capable enthusiasts. Positive-displacement systems are more complex, requiring 30-40+ hours and extensive engine disassembly. Professional tuning is recommended regardless of who performs installation, as proper calibration is critical for reliability and performance.

How much does it cost to supercharge a 5.7 Hemi Challenger?

Total costs range from $7,000-$16,000 depending on kit choice and supporting modifications. Budget builds using entry-level kits with DIY installation run $7,000-$9,000. Mid-range builds with professional installation and moderate supporting modifications cost $9,000-$12,000. Premium builds with top-tier kits, professional installation, comprehensive tuning, and extensive supporting modifications exceed $12,000-$16,000.

Do superchargers require premium fuel?

Yes, supercharged 5.7 Hemi Challengers require 91-93 octane premium fuel minimum. Higher octane fuel resists detonation under the increased cylinder pressures created by forced induction. Using lower octane fuel risks catastrophic engine damage from detonation. Most supercharger systems are designed around 91-93 octane pump gas, though race gas or E85 allows more aggressive tuning for maximum power.

How does supercharging affect fuel economy?

Fuel economy decreases 2-4 MPG with typical driving compared to stock. During steady-state cruising, the supercharger adds minimal fuel consumption. However, the additional power encourages more aggressive driving, and actual fuel economy suffers accordingly. Under full-throttle acceleration, fuel consumption increases significantly—a naturally aspirated engine might use 15-20 MPG worth of fuel during hard acceleration, while the supercharged version uses 8-12 MPG worth during equivalent acceleration.

Will my transmission handle supercharged power?

Stock transmissions handle moderately supercharged power (500-550 horsepower) adequately with proper driving techniques and avoiding aggressive launches. Beyond 550 horsepower or with frequent drag racing, transmission upgrades become necessary. Automatic transmissions benefit from performance torque converters and upgraded clutch packs. Manual transmissions need upgraded clutches rated for the increased torque output. For serious racing applications, complete transmission builds ensure reliability.

How much faster is a supercharged 5.7 Hemi Challenger?

Quarter-mile times improve from 13.8-14.2 seconds stock to 11.5-12.8 seconds supercharged, depending on power level and driver skill. 0-60 MPH times drop from 5.1-5.3 seconds to 3.8-4.3 seconds. The most dramatic improvement is 60-100 MPH roll-on acceleration, which decreases from 9-10 seconds to 5.5-6.5 seconds, making highway passing and roll racing performance exceptional.

Are centrifugal or positive-displacement superchargers better?

Neither is universally better—the ideal choice depends on priorities. Centrifugal superchargers offer better efficiency, less heat generation, easier installation, and more affordable pricing. They excel for top-end power and high-RPM performance. Positive-displacement superchargers (Roots, twin-screw) deliver superior low-end torque, instant throttle response, and stronger performance in typical street driving RPM ranges. They create a more dramatic, immediate power delivery that many enthusiasts prefer despite higher costs and increased installation complexity.

Making Your Decision

Selecting and installing a supercharger represents a significant investment that transforms your 5.7 Hemi Challenger’s performance and driving character. The right supercharger depends on your specific goals, budget, driving style, and tolerance for maintenance and complexity.

For street-focused enthusiasts wanting maximum low-end punch and addictive throttle response, twin-screw or Roots-style positive-displacement superchargers deliver the most satisfying daily driving experience. The instant boost production makes every acceleration feel dramatic, though you’ll pay premium prices and accept more complex installation.

Budget-conscious owners or those prioritizing top-end power find centrifugal superchargers compelling. They offer excellent value, straightforward installation, superior efficiency, and impressive high-RPM performance. The more gradual power delivery may feel less dramatic at lower speeds but creates a smoother, more controllable power curve.

Regardless of which supercharger you choose, prioritize quality installation and professional tuning. Cutting corners on installation or using generic tunes rather than custom dyno calibration risks expensive failures that negate any initial savings. Invest in proper supporting modifications—upgraded fuel systems, proper spark plugs, adequate cooling—to ensure your supercharged Challenger delivers reliable performance for years.

Supercharging your 5.7 Hemi Challenger isn’t just about horsepower numbers or quarter-mile times. It’s about enhancing the driving experience, making every drive more engaging and exciting. The combination of V8 sound, instant throttle response, and crushing acceleration creates an automotive experience that never grows old, transforming your Challenger into the performance machine it was always meant to be.
