Striker Hellcat Engine Specs — Power, Performance & What to Expect

The 6.2L Supercharged HEMI V8 — An Engine Like No Other

At the heart of every striker Hellcat sits the legendary 6.2-liter supercharged HEMI V8 — internally designated the Hellcat engine by Dodge and codenamed "Fury." This isn't a modified or aftermarket motor. It's a purpose-built, factory-engineered powerplant designed from the ground up to deliver extreme horsepower while maintaining the reliability and drivability of a daily driver.

The engine uses a 2.4-liter IHI twin-screw supercharger mounted in the valley between the cylinder banks. This supercharger force-feeds compressed air into the engine at up to 11.6 PSI of boost in the standard Hellcat and 14.5 PSI in the Redeye and Jailbreak variants. The result is an immediate, violent wall of torque that pins you to the seat the instant you touch the throttle. There's virtually zero turbo lag — the power is instantaneous because it's a supercharger, not a turbocharger.

The engine block is cast-iron for maximum strength, with forged steel connecting rods, sodium-filled exhaust valves, and a forged steel crankshaft — all built to handle the enormous pressures of forced induction. The heads are aluminum for better heat dissipation. Every component was overengineered from the factory, which is why the Hellcat engine has earned a reputation as one of the most reliable high-performance engines ever mass-produced.

Power Output by Variant

While all Hellcat engines share the same 6.2L supercharged V8 architecture, Dodge released several variants over the years — each with progressively more power. Here's how they stack up:

The difference between the standard Hellcat and the Redeye comes down to the supercharger. The Redeye uses the larger supercharger from the Demon — with a higher redline, bigger throttle body, and increased boost pressure. This pushes output from 707/717 HP to 797 HP with an additional 57 lb-ft of torque. The Jailbreak adds another 10 HP to reach 807, along with the ability to mix and match options that were previously locked to specific packages.

For most striker car buyers, the standard Hellcat (707/717 HP) is more than enough power — it's already faster than 99% of cars on the road. The Redeye and Jailbreak are for buyers who want the absolute maximum and are willing to pay the premium. View our current Hellcat inventory to see what's available.

Cooling Systems — How the Hellcat Stays Cool Under Pressure

Making 700+ horsepower generates enormous heat. Dodge engineered three dedicated cooling systems — on top of the standard engine cooling — specifically to keep the Hellcat engine running at optimal temperatures during sustained high-performance driving:

Hellcat Engine Reliability

One of the most common questions we hear from buyers: "Is the Hellcat engine reliable?" The short answer is yes — remarkably so. The Hellcat engine was built on the proven Apache/Hemi platform that has been in production since 2003. Dodge overengineered every critical component specifically because they knew owners would beat on these cars.

Common reliability concerns and the reality:

The bottom line: the Hellcat engine is one of the most reliable high-performance motors ever mass-produced. With basic maintenance — regular oil changes, coolant flushes, and supercharger belt inspections — these engines will last well beyond 150,000 miles without major issues.
