The APR Supercharger Crank Pulley Upgrade increases the factory crank pulley diameter from about 162mm to 187mm, which APR says spins the supercharger about 15.4% faster for a larger gain in horsepower and torque across the rev range. It is listed for supercharged 3.0 TFSI Audi A6, A7, A8, Q5, Q7, S4, S5 and SQ5 models. The pulley is CNC machined from lightweight billet aluminium with weight saving pockets and an anodised black finish, bolts over the top of the factory harmonically balanced crank pulley and comes with new crank pulley bolts. APR notes that specific software is required to maximise output and that a new belt is needed, RS100003 with a factory drive pulley or RS100002 with an APR drive pulley.
