With its 470 horsepower, the 6.4-liter HEMI V-8 engine from Dodge is one of the most awesome engines offered by the company. Most of you will agree that 470 horsepower is enough for the likes of the Challenger SRT8, the folks over Hennessey are offering a supercharger kit that will increase the V-8 engine’s output up to an impressive 800 horsepower.
The kit comes in three different power levels and the first one is the HPE600. As its name suggests, this package delivers a total of 600 horsepower and includes a TVS2300 supercharger system, HPE air induction system, an ECU recalibration and new fuel injectors.
Next there is the HPE650. It takes the power level up to an impressive 650 horsepower and over the HPE600 package it adds in headers and high-flow catalytic converters.
The most powerful version is the HPE800. As you probably guessed, this version delivers a total of 800 horsepower. This package adds new forged aluminum pistons, forged steel connecting rods, cylinder head porting, balancing and blueprinting, fuel injectors, a twin turbo system, and a new exhaust system.
Along with the engine upgrades, each package will offer optional upgrades for the transmission, exhaust and braking systems. Hennessey will also be offering exterior and interior changes, plus a new set of wheels and tires.
