ASP Underdrive pulley systems increase engine horsepower by reducing the amount of power required to drive external engine accessories. Auto mechanics use underdrive pulleys as a replacement pulley that contains a different ratio and material specifications that free up lost horsepower. By using an underdrive pulley, you are increasing the diameter of each accessory pulley and decreasing the ratio of the crank pulley. The speed at which the accessories are turning relative to the engine's rpm's decrease. By installing a resized pulley, the accessories are slowed. This results in more horsepower available to the drive wheels. Typically, a set of Auto Specialties street pulleys will increase horsepower by 12-15, and increase mileage by 2 to 3 MPG.Why should you buy an Underdrive Pulley by ASP? ASP has been in operation since 1988. All ASP pulleys are manufactured from Billet Steel or Aluminum, exceeding factory quality. ASP pulleys start out as as a solid bar of either 6061-T6 Alum or 1045-carbon steel. Order an ASP PULLEY system from LMPerformance and see the difference.
