The APR Supercharger Drive Pulley is a bolt-on upgrade for the 3.0 TFSI engine in the Audi A6 C7, A7 4G, A8 D4 and Q7 4M. APR says it reduces the diameter of the factory pulley from about 63.25mm to 57.75mm, which spins the supercharger about 9.5% faster and gives a healthy gain in horsepower and torque across the rev range. It is CNC machined from billet stainless steel and e-coated black to look like an OEM part, and it fits with new OEM bolts. Specific software is needed to maximise output, a new belt is required, and the pulley is only for bolted on pulleys, with APR directing owners of pressed on pulleys to part number MS100135.
