Description
APR presents the 3.0 TFSI Supercharger Crank Pulley Upgrade. APRs Supercharger Crank Pulley Upgrade dramatically increases horsepower and torque by increasing the rotational speed of the factory supercharger. APRs Stage II Pulley ECU Upgrade makes the necessary engine management adjustments to handle the increased supercharger speeds, and in turn allows the engine to create more power. The pulleys are sold separately, allowing for multiple levels of performance, each of which builds upon the other. Finally, when combined with APRs Ultracharger Throttle Body Upgrade in a dual pulley setup, the system is alleviated of power robbing inlet restrictions, allowing the engine to achieve exciting new levels of performance! APRs 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. *AS OF 3/6/17 Pulley Belt NOT INCLUDED Select from the drop down menu which belt is appropriate for your application *Only one Belt needed per car – if ordering APR Crank Pulley, choose the option that fits your setup. *Software Charge no longer included with price of the pulley and belt setup – contact your local APR Dealer for software pricing.
