To achieve the same boost with your current engine combo but with a 15% OD lower pulley we need to achieve the same blower RPM at 6500 RPM at the engine. 1 hertz to RPM = 60 RPM. It can be seen from the above formula, that widely differing pulley diameters located close together will result in the smaller pulley having a great deal less transfer capacity than the larger pulley. When selecting desired GPM, allow for a –5% tolerance on pumps output due to variations in pulleys, belts and motors among manufacturers. Also, note that with this type of setup, for a given supercharger displacement and pulley ratio, the less boost you make, the more power you will have, since this indicates that the engine is breathing better, and the supercharger doesn't have to compress the air as much to achieve the flow rate dictated by the pulley ratio and blower displacement. Practical Application: Broken Belt, Unkown Length. Designed to be mounted on the front of the passenger side head and can adjusts forward and backward to fit nearly any pulley groove, including the stock factory a/c belt groove. 2) are shown. τin = Torque of driver, ft-lbs.
