Increases horsepower by removing the engine's requirement to burn relatively non-combustible oil. Also improves intercooler efficiency by preventing the oil sludge coating that lowers thermal efficiency.
RIVA 300 XX Charger is installed. High performance billet impeller & 3MM spacer increase horsepower through superior impeller blade design and larger interior housing volume. Lightweight billet impeller features a sophisticated blade design that is precision balanced to deliver smooth operation. Spacer & impeller install quickly and easily onto stock supercharger base plate delivering 17.5 psi of boost pressure producing arm wrenching acceleration and increased top speed.
