APR Supercharger Drive Pulley Upgrade, Bolt-On Kit (AUDI 3.0L TFSI)

APR Supercharger Drive Pulley Upgrade
APR's Supercharger Drive Pulley Upgrade decreases the diameter of the factory pulley from ~63.25mm to 57.75mm, which 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 steel, e-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.

APR Stage II software is required to run any upgraded Pulley configuration and is sold separately
