The Hellcat Engine Is an Amazing Powerplant

The Challenger SRT Hellcat gets its power from a supercharged 6.2-liter Hellcat V8 that produces 707 horsepower at full tilt and is the most powerful V8 engine Dodge has ever created. Power travels to the rear wheels through either a beefy six-speed manual gearbox or an eight-speed automatic transmission.

At full power, the Hellcat V8 needs a massive supply of gas and air. The fuel lines are a half-inch in diameter, and two air intakes are necessary to provide enough oxygen to the engine. One is located in what looks like a driver's side headlight, and the other is under the hood. Two heat extractors on the hood help to remove engine heat.

The engine block is made of iron to withstand the intense performance demanded from it. The massive supercharger weighs 80 pounds, spins at up to 14,600 rpm at full power, and can push 30,000 liters of air per minute. Each engine spends 42 minutes on an engine dynamometer to ensure its performance before it is ever installed in a Challenger.
