Get up to 20HP on 84-91 Corvettes without modifying your engine with the pulley system. An undersized crankshaft pulley turns belt-driven accessories 25% slower preventing parasitic horsepower losses and an oversized alternator pulley (22%) and water pump pulley (23%) keep these accessories turning near their proper speed to provide the correct electrical charge and prevent overheating. Sets do not include belts, this will need to be purchased separate.
Not legal to use in California or no pollution controlled vehicles.
