The Kraftwerks Performance 90mm x 30mm supercharger pulley upgrade is designed to enhance the already impressive BRZ, FRS, FT 86, and AP1 S2000 supercharger kits. You can enjoy more low end torque and horsepower by replacing the supercharger pulley, allowing the supercharger to reach max speed sooner! The upgrade is especially handy if you don't plan on spinning the motor high in the RPM range but still want to maximize the performance of the supercharger.
BRZ, FRS, FT 86, and AP1 S2000 kits can all use this smaller 90mm pulley; consult the list below to understand the unique trade-offs before making your purchase.Â
