    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.

     

    Vehicle Supercharger Head Unit Std. Pulley Max RPM Upgrade Pulley Max RPM
    BRZ/FRS/FT86 Base/CARB Legal C30-94 95mm 7,800 90mm 7,400
    BRZ/FRS/FT86 Race C38-81 95mm 8,900 90mm 8,450
    AP1-S2000 Base C38-81 100mm 9,400 90mm 8,450

     

    NOTE - The 90mm pulley upgrade will work with your original belt but we highly recommend ordering a new one as part of good preventative maintenance or just to have a backup handy.

     

     **NOTE** You WILL need a new map to run with the high boost pulley kit.
