The 6.2-liter supercharged Hellcat Redeye V-8 is now being offered as a crate engine from Mopar. It's available to order now, with a starting price of $21,807.

Essentially the same engine used in the Dodge Challenger SRT Hellcat Redeye and Charger SRT Hellcat Redeye, the Hellcat Redeye crate motor produces 807 horsepower and 717 pound-feet of torque on 91-octane fuel. Those are increases of 100 hp and 67 lb-ft over the current "Hellcrate" engine, which Mopar will continue to sell alongside the Redeye engine.

While they are both 6.2-liter supercharged Hemi V-8s, the Redeye has a larger supercharger (2.7 liters, versus 2.4 liters for the Hellcrate), which puts out 14.5 psi of boost, compared to the Hellcrate's 11.6 psi of boost. The Redeye engine also boasts a higher redline of 6,500 rpm (versus 6,200 rpm for the Hellcrate) and other upgrades.

The basic engine assembly includes the supercharger, throttle body, fuel injectors, coil packs, water pump, front-sump oil pan, and flex plate. An optional Front End Accessory Drive Kit adds an alternator, power-steering pump, belt, pulleys, and mounting hardware.

Mopar also offers a flywheels, clutch, pressure plate, and mounting bolts for manual-transmission builds.

Just as Dodge now offers a staggering array of Hemi-powered Challenger and Charger variants, Mopar now has a long list of crate motors. In addition to the supercharged Hellcat Redeye and Hellcrate, the naturally-aspirated 5.7-liter and 6.4-liter V-8s used in various Dodge, Chrysler, and Jeep vehicles are also available as crate engines. Mopar also offers the Hellephant, a supercharged V-8 inspired by the classic 426 Hemi, and rated at 1,000 hp.
