Because of their 15% reduced diameter and 400% lighter weight, energy normally used to turn the heavy stock pulley is now used to turn your drive wheels! Usual power gains from 8-11 horsepower. In addition, the high performance lightweight 6061 billet aluminum Underdrive Power Pulleys are a perfect choice for road racing ,drag racing and autocross due the reduction of water pump cavitation. Horsepower gains vary widely depending on what has been done to the vehicle.
