Understanding the Edelbrock Supercharger Kit for the Dodge Durango Hellcat

The Dodge Durango Hellcat already delivers an astonishing 710 horsepower from its supercharged 6.2L HEMI V8, making it one of the most powerful SUVs ever produced. But for owners who crave even more – whether for track days, drag strip passes, or simply the thrill of uncontrollable torque – adding a more efficient aftermarket supercharger is a logical next step. Edelbrock’s $2,000 supercharger kit promises to unlock significant additional power without breaking the bank. However, the true cost of such an upgrade extends far beyond the kit’s price tag. This article breaks down every expense you’ll face, from parts and labor to tuning and supporting modifications, so you can budget accurately and make an informed decision.

What’s Included in the Edelbrock $2,000 Kit?

Before diving into costs, it’s critical to understand what you’re getting for that headline price. The Edelbrock supercharger kit for the Durango Hellcat is a positive-displacement unit (twin-screw or roots-type) designed to replace the factory IHI supercharger. It includes:

  • Supercharger assembly – a higher-flow, more efficient unit that can produce more boost with less heat soak.
  • Installation hardware – gaskets, bolts, brackets, belt, and hoses needed for a direct-fit installation.
  • ECU calibration software – a hand-held tuner or laptop-based software (often from HP Tuners or DiabloSport) to flash the factory ECU with new fuel and spark tables.
  • Installation instructions and support – detailed manuals and phone/email tech support.

Most kits also include an intercooler upgrade (a larger heat exchanger or higher-flow water pump) to manage increased heat from higher boost. Edelbrock’s reputation for quality ensures that the hardware is robust, but the tuning software is often a basic “canned” tune that may require professional calibration for optimal results.

Full Cost Breakdown: From $2,000 to the Final Total

While the kit itself is $2,000, the total investment to safely and reliably realize its potential will be significantly higher. Below is a realistic line-item breakdown for a professional installation with all recommended supporting mods.

1. Supercharger Kit – $2,000

This is your starting point. Note that some retailers may charge additional for shipping, especially if oversized. Taxes may apply depending on your state.

2. Professional Installation Labor – $800 – $1,500

Installing a supercharger on a Hellcat engine is not a weekend job for the average DIYer. Expect 12–20 hours of labor at $75–$150/hour. The work includes removing the factory supercharger, swapping the intercooler, upgrading the fuel injectors (if not included), and properly routing all hoses. A shop with Hellcat experience will charge a premium but ensure everything is torqued to spec.

3. ECU Tuning – $500 – $1,200

Even if the kit includes a basic tune, a custom dyno calibration is strongly recommended. Hellcat engines are sensitive to air/fuel ratios and timing; a poor tune can lead to detonation and catastrophic failure. Professional tuning from a reputable shop (like Dusterhoff, HHP, or BBP) typically costs $500–$1,000 for a baseline + $200–$300 for additional revisions. If you purchase a separate tuning platform like HP Tuners MPVI2+ (around $400), add that cost as well.

4. Fuel System Upgrades – $400 – $1,200

The factory fuel system can support up to roughly 800–850 whp. If the Edelbrock kit aims for 900+ whp, you will likely need larger injectors (e.g., 1000cc or more) and possibly a higher-flow low-pressure fuel pump. Many Hellcat owners also upgrade to a Fore Innovations fuel system or a Lingenfelter fuel pump booster. Budget $200–$400 for injectors and $200–$800 for a fuel pump upgrade.

5. Cooling System Improvements – $300 – $800

More power generates more heat. Upgrading the intercooler heat exchanger to a larger unit (like those from AFE, Mishimoto, or LMR) and adding an auxiliary cooling pump can prevent heat soak. A secondary transmission cooler may be wise for the 8HP95 eight-speed automatic, which can overheat under sustained heavy load. Budget $200–$400 for a larger heat exchanger and $100–$400 for transmission cooling.

6. Exhaust Modifications – $0 – $1,500

The factory exhaust is restrictive. A cat-back or full exhaust system (e.g., Borla, MagnaFlow, or Corsa) will free up horsepower and enhance the supercharger whine. If you have the budget, expect $1,500–$2,500 for a quality system. However, many owners run the stock exhaust with the stock manifolds and still see good gains.

7. Supporting Items & Incidentals – $200 – $500

  • Colder spark plugs (NGK 6510 or equivalent) – $50
  • Oil catch can (to prevent blow-by oil from contaminating the intake) – $150
  • Gaskets, fluids, misc. hardware – $100
  • Dyno time (if not included in tune) – $250–$500

Total Estimated Cost

Summing the conservative estimates:

Low-end (DIY install, no fuel/cooling upgrades, basic tune): $2,000 (kit) + $500 (tune) + $200 (incidentals) = $2,700
Mid-range (professional install, fuel & cooling upgrades, custom tune): $2,000 + $1,200 (labor) + $800 (tune) + $800 (fuel) + $500 (cooling) + $300 (incidentals) = $5,600
High-end (full supporting mods, premium exhaust, multiple tunes): $2,000 + $1,500 (labor) + $1,200 (tune) + $1,200 (fuel) + $800 (cooling) + $1,500 (exhaust) + $500 (incidentals) = $8,700

Most owners will end up somewhere in the $5,000–$7,000 range to do the job correctly. The original $2,000 kit price is an excellent starting point but is only a fraction of the real investment.

Installation: DIY vs. Professional – Real Costs and Risks

If you have mechanical experience and a well-equipped garage, you might save $1,500 in labor. However, the installation is not trivial. The factory supercharger is heavy and requires precise alignment to avoid belt squeal or interference with the engine cover. Special tools like a torque wrench that reads foot-pounds in the mid-200 range, a floor jack to lift the supercharger, and a scan tool to monitor air intake temperatures are necessary. Do-it-yourselfers should budget at least 25–30 hours and be prepared to purchase a service manual.

Professional installation offers peace of mind: shops have lifts, experience with hellcat engines, and often provide a warranty on labor. They also handle the initial tune and can identify any underlying issues (like fuel pressure drops or vacuum leaks) that a DIYer might miss.

Step-by-Step Install Overview (Professional Route)

  • Drain coolant, remove factory air intake and intercooler plumbing.
  • Remove the factory supercharger (several hours due to bolts and wiring).
  • Swap the intercooler bricks (the new kit likely includes a lower restriction core).
  • Install new injectors and, if needed, the fuel pump booster.
  • Mount the Edelbrock supercharger using supplied bracket and belt tensioner.
  • Connect intercooler hoses, bypass valve, and vacuum lines.
  • Flash the ECU with the provided calibration or custom tune.
  • Prime the fuel system, check for leaks, and perform a test drive.

Performance Gains: What Can You Expect?

Edelbrock claims up to 300 additional horsepower with their kit on a stock Durango Hellcat. Real-world dyno results from forums and shops show more realistic gains of 150–200 horsepower to the wheels (about 180–240 crank horsepower), depending on fuel quality, ambient temperature, and supporting mods. Torque increases are equally impressive, often reaching 700–800 lb-ft at the wheels. The supercharger’s positive-displacement design means boost comes on almost instantly, improving throttle response from idle to redline. The whine from the supercharger will be noticeably louder and higher-pitched, which many enthusiasts love.

Important note: The internal engine components (pistons, rods, crankshaft) in the Hellcat are forged and can handle 800–850 whp reliably. Beyond that, you risk bending rods or lifting the heads under high boost. If you plan to race frequently, consider head studs and a stronger oil pump as future upgrades.

Necessary Supporting Modifications for Reliability

To safely run the Edelbrock supercharger at its maximum potential, you must address the following:

  • Fuel system: Upgrade injectors and low-pressure fuel pump to maintain proper air/fuel ratios under heavy throttle. The factory DI system can run out of capacity above 850 whp.
  • Cooling: A larger intercooler heat exchanger and high-flow pump are essential to keep intake air temperatures below 140°F. Heat soak will cause the ECU to pull timing and reduce power.
  • Tune: A custom dyno tune is non-negotiable. Canned tunes are safe but conservative; a professional tuner can extract an extra 30–50 hp while maintaining safety margins.
  • Oil catch can: Prevents oil from the PCV system getting into the intake, which can cause detonation.
  • Spark plugs: One or two heat ranges colder to prevent pre-ignition under boost.

Warranty and Insurance Considerations

Adding a supercharger will void your factory powertrain warranty. Dodge’s warranty terms explicitly exclude modifications that increase horsepower beyond OEM specifications. Some dealers are mod-friendly, but most will deny any engine or transmission claim. You may consider a third-party powertrain warranty that covers modified vehicles, but these are rare and expensive.

Insurance: Inform your carrier about the modification. Premiums typically increase by 10–20% for a supercharger upgrade, depending on the insurer and your driving record. Failure to disclose could lead to claim denial if you have an accident.

Real-World Owner Experiences

From online forums and owner reviews, the Edelbrock kit is praised for its fit and finish. It bolts directly onto the Hellcat engine without requiring custom fabrication. Owners report a dramatic improvement in mid-range torque – the SUV feels much more responsive in everyday driving. However, those who install the kit without upgrading the cooling system often complain about heat soak after a few hard pulls, leading to power reduction. The most satisfied owners have invested in a full supporting package.

“The Edelbrock kit transformed my Hellcat Durango. It now pulls harder than my friend’s tuned Hellcat Challenger. But I had to spend another $3,000 on fuel upgrades and a custom tune before I felt safe driving it hard.” – anonymous forum user

Comparing Edelbrock to Other Options

The $2,000 price point is exceptional. For comparison:

  • Whipple W175AX: ~$3,500–$4,000; makes more boost (up to 12 psi), requires even bigger fuel system; more top-end power but costs more.
  • Magnuson 2650: ~$3,000; similar design to Edelbrock; excellent drivability but heavier.
  • ProCharger D-1X centrifugal: ~$5,000; different power delivery (linear, not instant torque); requires different tuning approach.

Edelbrock’s advantage is the value – you get a high-quality positive-displacement supercharger for significantly less than competitors. Its moderate boost level (~8–9 psi) keeps engine stress manageable, making it a great “stage 2” upgrade without requiring internal engine work.

Where to Buy and Get Help

Purchase the Edelbrock supercharger kit directly from Edelbrock or from authorized dealers like Summit Racing or American Muscle (though the latter focuses on Mustangs, so check). For tuning and installation, consult Hemi Tuner or local performance shops with Hellcat experience. For community support, the Durango Hellcat Forum is an excellent resource for real-world advice, dyno sheets, and troubleshooting.

Is the Edelbrock $2,000 Supercharger Kit Worth It?

Yes – but only if you budget for the full package. The kit alone is a bargain, but skimping on supporting mods will leave you disappointed or even with a broken engine. For around $5,000–$6,000 total, you can have a Durango Hellcat that easily surpasses 800 whp, with improved throttle response and a glorious supercharger whine. That’s still less than a new sport sedan and offers unmatched SUV performance. If you are prepared for the maintenance, fuel costs, and possible warranty sacrifice, the Edelbrock kit is one of the best ways to maximize your Hellcat’s potential.

Carefully plan your budget, choose a trusted shop, and enjoy the thrill of a truly wild high-performance SUV.
