The 5.7-liter Hemi V8 has been a staple of Chrysler, Dodge, Ram, and Jeep performance since its debut in 2003. Combining a reliable iron-block or aluminum-block architecture with hemispherical combustion chambers, this engine responds exceptionally well to forced induction. A supercharger kit is one of the most effective ways to unlock serious horsepower, often adding 150–250 hp at the wheels with safe tuning. However, choosing the right kit is critical—not all superchargers are created equal, and the best for you depends on power goals, driving style, budget, and installation preferences.

This guide breaks down the leading brands offering 5.7 Hemi supercharger kits: Magnuson, Edelbrock, Whipple, ProCharger, and others. We'll cover design philosophy, power output, drivability, installation complexity, and value—so you can make an informed decision.

Magnuson Supercharger Kits

Heart of the System: Eaton TVS Roots-Style Blower

Magnuson is the go-to name for positive-displacement roots-style superchargers on the 5.7 Hemi. Their kits are built around Eaton TVS (Twin Vortices Series) rotors, which feature a high-helix design for reduced noise, lower discharge temperatures, and improved volumetric efficiency over older roots blowers. Magnuson’s 2650 (2.65L) and 2300 (2.3L) units are the most common fitments for the 5.7.

Street-Oriented Power Delivery

Magnuson superchargers deliver boost from idle, building linearly to redline. This instant throttle response makes them ideal for daily drivers and stop-light performance. Typical gains with a Magnuson kit on a stock 5.7 Hemi are 130–170 hp at the wheels on 91 octane, and up to 200+ hp with E85 and supporting mods. The powerband is broad and predictable, never feeling laggy.

Integrated Intercooler

All modern Magnuson kits include an air-to-water intercooler integrated into the supercharger housing. This keeps intake charge temperatures consistently low, reducing the risk of detonation and allowing for more aggressive timing. The intercooler system includes a heat exchanger, pump, and reservoir—everything needed for safe high-boost operation.

Installation and Tuning

Magnuson targets the DIY enthusiast. Their kits include color-coded wiring harnesses, detailed instructions, and all necessary hardware. A factory supercharged calibration (via handheld tuner or custom dyno tune) is required, but Magnuson provides base maps. Because of the supercharger’s compact design, most kits require minimal hood modifications—factory strut tower braces typically remain untouched. Installation time averages 8–12 hours for a moderately experienced mechanic.

Warranty and Support

Magnuson backs their kits with a 12-month limited warranty. Their technical support team is knowledgeable and responsive, often helping with tuning questions. For a 5.7 Hemi owner looking for a street-legal (CARB EO on many kits), no-compromise daily-driver supercharger, Magnuson is a top contender.

Edelbrock Supercharger Kits

E-Force Series: Roots with a Twist

Edelbrock’s E-Force line is another Eaton TVS-based solution, similar in core technology to Magnuson but with unique engineering choices. The E-Force system uses a low-profile intercooler that sits between the supercharger and intake manifold, keeping the overall height low enough to fit under most factory hoods without cutting. This is a major selling point for truck and SUV owners who want a stealth setup.

Power and Drivability

Edelbrock superchargers are tuned conservatively from the factory for safety and longevity. On a 5.7 Hemi, expect 120–150 whp gains with the included calibration. The power comes on smoothly, with a slight surge in the midrange—perfect for towing, merging, and enjoying that characteristic roots whine.

CARB Compliance and Warranty

Edelbrock has obtained CARB Executive Orders (EO) for the majority of their 5.7 Hemi kits, covering Dodge Challenger, Charger, Ram 1500, and Jeep Grand Cherokee applications. This makes the E-Force a prime choice for owners in California and other states requiring emissions compliance. Edelbrock also offers a 3-year/36,000-mile warranty on supercharger components, one of the best in the industry.

Installation Details

Edelbrock kits are well-engineered for straightforward installation. They include a pre-programmed ECU flash tool (DiabloSport i3 or similar) that eliminates the need for a separate dyno tune. The kit replaces the factory intake manifold, so you’ll remove much of the top end—but the instructions are clear. Estimated installation time is 10–14 hours.

Who Is It For?

Edelbrock is ideal for the owner who values warranty coverage, emissions legality, and daily comfort above peak power numbers. The E-Force provides reliable, repeatable performance without requiring fuel system upgrades (on moderate boost levels). If you want a supercharger that feels factory-integrated and worry-free, Edelbrock delivers.

Whipple Supercharger Kits

Twin-Screw Design: More Boost, More Flow

Whipple is synonymous with twin-screw superchargers, using proprietary rotors that compress air internally rather than pushing it like a roots blower. This allows Whipple blowers to generate higher boost pressures more efficiently, with lower discharge temperatures at equivalent boost levels. Their new W175AX and W155AX units are optimized for the 5.7 Hemi.

Power Potential

Whipple kits are designed for those who want the absolute highest horsepower from a bolt-on system. A stage 1 Whipple on a 5.7 typically yields 170–210 whp gains on 93 octane. With upgraded injectors, a fuel system, and E85, many owners crack the 600+ wheel horsepower mark. Whipple’s rotors are coated for durability, and the housings are heavy-duty cast aluminum.

Tuning and Calibration

Whipple includes their own handheld tuner with pre-loaded calibrations. However, to take full advantage of the twin-screw design’s efficiency, a custom dyno tune is highly recommended. The kits include larger fuel injectors (typically 65 lb/hr or 80 lb/hr) and a boost-referenced fuel pressure regulator to maintain proper fuel delivery. Whipple also supports flex-fuel tuning for E85.

Installation Complexity

Twin-screw superchargers are physically larger and heavier than roots units. Installation may require modifications to the hood liner, strut tower brace, and in some cases the windshield washer reservoir (on Ram trucks). Whipple provides detailed instructions, but the process is more labor-intensive—expect 12–16 hours for a first-time installer.

Cold-Air Intake Included

Whipple kits come with a high-flow cold-air intake and an enclosed air box that draws air from the fender, reducing intake temperatures. The intercooler system is an air-to-water unit with a massive heat exchanger that can be mounted in the front bumper for maximum cooling.

ProCharger Supercharger Kits

Centrifugal Supercharging: The Turbo Alternative

ProCharger uses a centrifugal design, similar to a turbocharger but mechanically driven by the crankshaft. Their self-contained (oil reservoir) gearcases make installation cleaner—no tapping into the engine oil system. The P-1X and D-1X head units are the most common choices for the 5.7 Hemi.

Power Delivery: Top-End Rush

Centrifugal superchargers build boost progressively with engine rpm, delivering a strong pull above 4,000 rpm. This yields a naturally-aspirated feel around town with a massive surge at the top. Gains on a ProCharger kit range from 140–200 whp, depending on pulley size and boost level. The P-1X is capable of 650+ hp with intercooling.

Installation and Packaging

ProCharger kits mount the blower in the front of the engine (replacing the alternator location on some applications or mounting via a bracket). This leaves the top of the engine open, making spark plug changes and valve cover access easy. The included air-to-air intercooler is mounted in front of the radiator. Installation time is comparable to a turbo kit—around 10–14 hours.

Tuning Requirements

ProCharger includes a handheld tuner with base maps, but because centrifugal blowers have a different boost curve than positive-displacement units, a dyno tune is strongly recommended to optimize spark timing and fuel trims. ProCharger also offers a 3-year warranty on their head units.

Advantages and Trade-offs

The main benefit of ProCharger is its efficiency and lower heat soak—air-to-air intercooling means no water pump or heat exchanger to fail. However, the blower noise is distinct (a high-pitched whine) and the powerband may feel less torquey than a roots or twin-screw system. It’s a fantastic choice if you want to retain a stock-looking engine bay and maximize top-end horsepower.

Other Notable Brands: Roush and Vortech

Roush: Limited 5.7 Hemi Availability

Roush superchargers are best known for Ford applications, but they do offer kits for the 5.7 Hemi in certain Ram and Dodge vehicles. Roush uses an Eaton TVS blower (similar to Magnuson and Edelbrock) and includes a Roush-specific calibration. However, kits are often discontinued or difficult to source. If you find a Roush kit new-in-box, it’s a solid option—but aftermarket support and tuning may be limited compared to the big three.

Vortech: Quality Centrifugal Alternative

Vortech Engineering produces centrifugal supercharger systems for the 5.7 Hemi, notably the V-3 Si and V-7 JT units. Vortech kits include a high-flow bypass valve, cast-aluminum mounting brackets, and air-to-air intercoolers. They are known for low heat soak and good top-end power. Vortech’s head units are gear-driven and self-contained, similar to ProCharger. Support and tuning resources are solid, though the brand is less popular for Mopar applications. Gains are comparable to ProCharger—around 130–180 whp depending on system.

Critical Considerations When Choosing a 5.7 Hemi Supercharger Kit

Fuel System Upgrades

Virtually all 5.7 Hemi supercharger kits require larger fuel injectors. Most include injectors rated 65–80 lb/hr. However, if you plan to run higher boost or E85, you may need a boost-a-pump (BAP) or a complete fuel system upgrade (e.g., dual pumps, fuel rails, and lines). Factor this into your budget—especially for Whipple and high-boost centrifugal setups.

Spark Plugs and Ignition

Forced induction demands colder spark plugs to prevent pre-ignition. Most kits specify a heat range colder than stock (e.g., NGK 6510 or 6319). Gap the plugs tighter—typically 0.030–0.035 inches. Ignition coils are usually stock, but upgrading to high-energy coils may help if you encounter misfires at higher boost.

Cooling System

Adding a supercharger increases engine heat load. For daily-driven vehicles, a larger radiator and high-flow thermostat are recommended. If you tow or live in hot climates, consider an auxiliary transmission cooler as well. For roots/twin-screw kits, the air-to-water intercooler system must be properly bled and maintained.

Transmission and Drivetrain

The 5-speed or 8-speed automatics in most 5.7 Hemi vehicles can handle moderate boost (450–500 whp) with a proper tune and possibly a transmission cooler. Above 550 whp, upgraded torque converters, valve bodies, and clutches are advised. Six-speed manual transmissions (Tremec TR-6060) are robust, but the clutch will need upgrading beyond 500 whp.

Emissions Compliance

If you live in a state with emissions testing, look for a 50-state legal kit with a CARB EO number. Magnuson and Edelbrock offer the widest coverage. Whipple kits are not CARB-approved for most 5.7 Hemi applications (except old models). ProCharger has CARB-approved kits for some Mopar models, but check the EO list before buying.
