ATI – Serpentine Supercharger Front Drive Pulley for GM L86 (916358)

The ATI designed the Super Pulley to eliminate blower belt failure. This unique Supercharger Super Pulley allows your Supercharger to “freewheel” when the throttle is closed. It’s ideal for both competition and street applications. The Super Pulley uses ATI’s Superior Sprag Technology to release the blower when it is spinning faster than the engine RPM, virtually eliminating belt failures when the car is pedaled at the drag strip. Providing more boost between shifts, as the blower will not ramp down as fast as the engine during the gear change. Finally, the pulley will reduce wear on your Supercharger by not allowing the gear drive to mesh in the opposite direction when spinning down.
