Description
APR’s Supercharger Drive Pulley Upgrade decreases the diameter of the factory pulley from ~63.25mm to 57.75mmwhich in turn spins the supercharger ~9.5% faster. This results in a healthy bump in horsepower and torque across the entire RPM range with the supercharger operating at a higher rate of speed. The pulley is CNC machined from billet stainless steele-coated black for an OEM appearance and is press fitted to the factory supercharger unit on Gen 1 models and bolted on on Gen 2 models with new OEM bolts.
