Product Description
APR’s Supercharger Drive Pulley Upgrade decreases the diameter of the factory pulley from 63.25 Millimeter to 57.75 Millimeter, which in turn spins the supercharger ~9.5 percent 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 steel, e-coated black for an OEM appearance and is bolted to the factory supercharger unit. APR’s Supercharger Crank Pulley Upgrade increases the diameter of the factory pulley from ~162 Millimeter to ~187 Millimeter, which in turn spins the supercharger ~15.4 percent faster. This results in a larger bump in horsepower and torque across the entire RPM range, as the supercharger is spinning at an even higher rate of speed. The pulley retains the factory harmonically balanced crank pulley and bolts on top of the existing unit. It is CNC machined from light weight billet aluminum with weight saving pockets throughout. It has an anodized black finish and includes new crank pulley bolts.
