The APR Supercharger Drive Pulley is a smaller-diameter drive pulley for the factory supercharger on the 3.0 TFSI in the Audi A6, A7, A8, Q5, Q7, S4, S5 and SQ5. It reduces the factory pulley diameter from about 63.25mm to 57.75mm, which APR says spins the supercharger about 9.5% faster for a noticeable gain in horsepower and torque across the rev range. It is CNC machined from billet stainless steel, finished in black e-coat to look OEM, and press fitted onto the factory supercharger. APR notes that specific software is required to maximise output, that it suits pressed-on pulleys only, and that a new belt is required.
