High-Performance Hellcat Supercharged Engine Assembly 38kmills

Hellcat Supercharged Engine for Sale. Low Mileage 6.2L Supercharged HEMI Assembly.

The Hellcat supercharged engine is the most recognized factory forced induction V8 in modern American muscle. If you own a Dodge Challenger, Charger, or Jeep Grand Cherokee Trackhawk equipped with the Hellcat and need a replacement engine after an internal failure, or if you are building a swap project that calls for a factory supercharged HEMI with real output and proven reliability, a clean low mileage Hellcat 6.2L engine from a verified donor vehicle is the direct path to factory spec performance. At McClain Auto Part, we have been sourcing and selling used performance engines out of Cleveland, Ohio since 2009. The Dodge Hellcat engine is one of the most consistently requested forced induction units we carry.

Hellcat owners and builders come to us for a few reasons. Some need a direct factory replacement after a spun bearing, a supercharger failure, or an internal mechanical issue on a high-output car that has seen track use. Others are rebuilding a Challenger or Charger after an accident and need a verified low mileage engine with documented history. In addition, a growing group of builders specifically sources the supercharged HEMI engine for swap projects into classic Dodge muscle cars, custom chassis builds, and restomod applications where the Hellcat’s factory supercharged output is the specific performance target.

Whatever the situation, the goal is the same. A tested, documented Hellcat engine assembly that installs correctly and performs the way Dodge intended.

The Hellcat 6.2L Supercharged HEMI Platform

Dodge introduced the Hellcat engine in the 2015 Challenger SRT Hellcat. At the time, it was the most powerful production V8 in an American muscle car. The formula was straightforward. Take the proven 6.2L HEMI architecture, add a factory Eaton TVS positive displacement supercharger, and build the supporting components to handle the sustained output. The result was 707 horsepower from a production engine that Dodge warranted and sold to the general public.

What Makes the Hellcat Engine Different From a Standard HEMI

The standard 6.4L 392 HEMI and the naturally aspirated 5.7L HEMI share the same basic pushrod V8 architecture as the Hellcat. However, the Hellcat 6.2L uses a unique block casting, revised cylinder heads with improved flow characteristics, a forged crankshaft, stronger connecting rods, and lower compression pistons designed to work with the forced induction system. These differences matter for anyone sourcing a replacement. A standard 6.4L HEMI is not a Hellcat replacement. Confirm your engine is a Hellcat application before ordering.

Eaton TVS Supercharger System

The Hellcat 6.2L engine uses an Eaton TVS 2650 positive displacement supercharger mounted directly on the intake manifold. The TVS design uses twisted rotor lobes that reduce internal temperature and improve volumetric efficiency compared to older Roots-type designs. The supercharger drives from the front of the engine via a dedicated belt system. This setup delivers boost immediately from low RPM, giving the Hellcat its characteristic broad power curve and strong torque response across the entire RPM range.

Hellcat Versus Hellcat Redeye Versus Super Stock

The Hellcat engine family expanded over the years. The standard Hellcat produces 707 horsepower. The Hellcat Redeye uses a larger supercharger and produces 797 horsepower. The Super Stock variant produces 807 horsepower. These are different engine specifications with different supercharger and calibration setups. Confirm which variant your vehicle uses before ordering. Call us with your VIN and we confirm the correct unit for your application.

A Note on ECU and Wiring

The Hellcat ECU calibration is specific to the supercharged 6.2L system, fuel management, and transmission pairing of the original vehicle. For a direct factory replacement in the original car, your existing ECU and harness are typically reused with the replacement engine. For a swap application into a non-factory chassis, confirm your ECU and wiring solution before ordering. Tell us your application when you call and we confirm what is available in current inventory.

Condition and Inspection

Every Dodge Hellcat engine that ships from our Cleveland warehouse goes through a thorough inspection. The supercharger system, forced induction fuel demands, and higher internal stress of a 700-plus horsepower engine require specific inspection attention that naturally aspirated engines do not.

What We Check Before Every Unit Ships

• Compression test on all eight cylinders, actual numbers recorded
• Full visual inspection of block, heads, and external surfaces for cracks, leaks, or damage
• Oil condition checked for metal contamination, debris, or signs of bearing distress
• Coolant passages inspected for signs of mixing or head gasket issues
• Mileage verified against donor vehicle documentation
• Supercharger assembly inspected for shaft play, rotor condition, and snout integrity
• Supercharger belt drive and tensioner condition noted
• Fuel rail and injector condition inspected
• No audible knocking, ticking, or boost leak confirmed before packaging

Supercharger condition and oil system condition are documented separately on every unit before it ships. You receive that documentation before the order is finalized.

Vehicle Compatibility

The Hellcat supercharged engine was factory-fitted in the following vehicles:

• Dodge Challenger SRT Hellcat, 2015 to present
• Dodge Challenger SRT Hellcat Redeye, 2019 to present
• Dodge Challenger SRT Super Stock, 2020 to present

Call us with your VIN and we confirm the correct unit for your application.

Common Swap Applications

The supercharged HEMI engine is a growing platform for swap projects outside the factory Mopar chassis. Common applications include:

• Classic Dodge Charger, E-body and B-body builds
• Plymouth Cuda and Barracuda restomod projects
• Custom tube chassis and street builds
• First-gen Challenger restomod applications
• Any rear-wheel drive build where factory supercharged HEMI output is the target

For swap applications, confirm your ECU solution, fuel system capacity, transmission selection, and chassis clearance for the supercharger assembly before ordering. Call us with your application and we give you practical guidance on what the build requires.

Swap and Installation Notes

ECU and Wiring

The Hellcat ECU manages the supercharger bypass valve, dual-mode fuel system, and transmission integration. For swap applications, a dedicated Hellcat swap harness from a supplier familiar with the SRT platform is the most common solution. A standalone ECU that supports the Hellcat supercharger system is also an option. Confirm your electronics solution before ordering the engine.

Fuel System

The Hellcat at full output requires significant fuel delivery capacity. The factory dual-fuel pump system in the Challenger and Charger is sized for this engine. For swap applications, confirm your fuel pump flow rate, injector sizing, and fuel line capacity match the engine’s demands. Under-fueling at high output causes detonation and internal damage quickly on a forced induction engine.

Cooling System

The Hellcat uses two separate cooling circuits. The main engine cooling circuit handles the block and heads. A separate supercharger heat exchanger circuit cools the charge air between the supercharger and the intake ports. Both circuits need to be properly routed, sized, and bled in a swap application. Confirm both cooling circuits are in your build plan before ordering.

Transmission

The Hellcat was paired with the Tremec TR-6060 6-speed manual or the 8HP90 8-speed automatic in factory applications. For swap builds, confirm bellhousing bolt pattern and input shaft compatibility for your specific transmission. The 8HP90 is a strong automatic option if you want to retain the factory pairing in a swap.

Hood Clearance

The Hellcat supercharger assembly adds significant height to the engine. Confirm hood clearance in your chassis before ordering. Classic Mopar builds and many custom applications require hood modifications to clear the supercharger assembly.
