APR Supercharger Drive and Crank Pulley with Belt Press on Audi A6/A7/A8/Q5/Q7/S4/S5/SQ5 3.0TFSI

This APR kit pairs a smaller supercharger drive pulley with a larger crank pulley and a belt to spin the factory supercharger faster on 3.0 TFSI Audi A6, A7, A8, Q5, Q7, S4, S5 and SQ5 models. The drive pulley shrinks from about 63.25mm to 57.75mm for roughly 9.5% more supercharger speed, and the crank pulley grows from about 162mm to 187mm for roughly 15.4%, which together APR says spin the supercharger about 26.4% faster than stock. The drive pulley, machined from billet stainless steel by CNC, has a black e-coat and press fits to the supercharger, while the lightweight billet aluminium crank pulley is anodised black, bolts on top of the factory harmonically balanced unit and comes with new bolts. APR notes that specific software is required to maximise output and that its Ultracharger Throttle Body Upgrade is needed to get the full benefit of a dual pulley setup.
