949 Horsepower Pulley Bolts

32a. There are just a few more pieces to go. Holley ships the supercharger kit with a pulley combination that will spin the blower to produce between 5 and 7 pounds of boost. The lower pulley bolts onto this V-belt pulley, which is bolted onto the TCI Rattler dampener. The upper pulley bolts onto the supercharger and the belt is routed around the idler pulley. We are running a 52-tooth upper pulley and 50-tooth lower pulley to drive the blower 4 percent under what the motor is spinning. This yields 7-1/2-psi boost, which is plenty to build the power we are after. View Related Article
