APR Supercharger Drive & Crank 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 Supercharger Crank Pulley Upgrade
APR's Supercharger Crank Pulley Upgrade increases the diameter of the factory pulley from ~162mm to ~187mm, which in turn spins the supercharger ~15.4% 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.

Please note: For 3.0 TFSI Gen 2 engines (Simos 16), the Supercharger Crank Pulley is only available when used in a dual pulley configuration.

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