6.4-Liter V8 Hemi Engine Gets Hennessey Supercharger Kit
The first of the kits is called the HPE600, and as its name suggests, it boosts power to 600 hp, through the use of a TVS2300 supercharger, HPE air induction system, new fuel injectors and an ECU remap.
The next step up is the HPE650, which gets high-flow catalytic converters and headers, for a combined result of 650 hp. The most powerful kit is the HPE800, which delivers 800 hp, by adding forged aluminium pistons, forged steel connecting rods, new fuel injectors, as well as a twin-turbo system.
However, it is not recommended to boost the car’s power to such high levels without fettling with the brakes and transmission, so Hennessey is also offering optional upgrade parts, as well as various interior and exterior upgrades, plus new rims and tires.
