Chevrolet Corvette ZR1
From Chevrolet: The ZR1(1) is powered by a 6.2 Liter aluminum-block V8 boosted by Eaton® TVS™ (Twin Vortices Series) supercharger for a total power output of 638 hp at 6500 rpm and 604 lb.-ft. of torque at 3800 rpm. It is the most powerful motor ever to occupy the engine bay of a General Motors production car. The supercharger features four lobes instead of the usual three for higher power and efficiency. It also features an intercooler to cool down the airflow charge for more power. In addition, nozzles squirt cooling oil into the underside of each piston.
