APR presents the 3.0 TFSI Supercharger Drive and Crank Pulley Upgrades.
APR’s Supercharger Drive and Crank Pulley Upgrades dramatically increase horsepower and torque by increasing the rotational speed of the factory supercharger. APR’s 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 APR’s 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!
APR Supercharger Drive Pulley Upgrade
APR’s Supercharger Drive Pulley Upgrade decreases the diameter of the factory pulley from ~63.25mm to 57.75mm, which in turn spins the supercharger ~9.5% faster. This results in a healthy bump in horsepower and torque across the entire RPM range with the supercharger operating at a higher rate of speed. The pulley is CNC machined from billet stainless steel, e-coated black for an OEM appearance and is press fitted to the factory supercharger unit on Gen 1 models and bolted on on Gen 2 models with new OEM bolts.
APR Supercharger Crank Pulley Upgrade
APR’s 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.
Please note: For 3.0 TFSI Gen 2 engines (Simos 16), the Supercharger Crank Pulley is only available when used in a dual pulley configuration.
APR Supercharger Dual Pulley Upgrades
Upgrading both the supercharger drive and crank pulleys results in the factory supercharger spinning ~26.4% faster than stock. This speed was chosen after extensive engine and chassis dyno testing with various pulley sizes and supercharger speeds. The result is an even higher horsepower and torque gain across the entire RPM range. However, at the airflow levels achieved with a dual pulley setup, maximum power is severely restricted by the factory throttle body unit. The APR Ultracharger Throttle Body Upgrade is necessary to take full advantage of the dual pulley configuration, and is available in platform specific variations for the B8/B8.5 A4/A4/S4/S5, Q5/SQ5 and C7 A6/A7.

Supercharger Drive Pulley Removal Tool
The factory Gen 1 supercharger drive pulley is pressed on to the supercharger's input shaft. It's not possible to remove the factory pulley without damage, or damaging the supercharger itself unless special care and attention is taken.
The APR Supercharger Drive Pulley Installation Kit is designed to encapsulate the entire pulley and pull evenly across its entire surface. The unit is compact enough to not require complete removal of the front end of your vehicle, reducing labor time. Furthermore a provision was made to incorporate a 1/2 inch drive breaker bar which allows the entire assembly to be easily counter-held and ultimately makes the process a one man job.
A complete install manual covers the install process from start to finish, making installation easily completed at any APR dealer or in your own garage.
