APR 3.0 TFSI Supercharger Drive and Crank Pulley Upgrades

More Horsepower

More Torque

57.75 mm Supercharger Drive Pulley

187 mm Supercharger Crank Pulley

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.

- APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode.
- Max increases are based on APR's actual measured stock values and not those reported by Audi. | RON = ROW Fuel Grades | AKI = North American (RON+MON)/2 Fuel Grades.
- Reported wheel figures measured using APR's in house dynos using SAE J1349 correction and an average of multiple runs for all figures. Crank figures are estimated based on the measured wheel figures and APR's engine dyno results. Results will vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications. For the best results, APR recommends removing the intake snow screen.
- Please note, transmission software is required to achieve power figures past the factory redline.

This product is designed for use with APR's S Tronic TCU Upgrade, NGK BKR9EIX plugs gapped @ .024” +/- .002” torqued to 30Nm and a new supercharger belt. The APR Supercharger Cooling System is highly recommended and required with the dual pulley setup. IAT’s must be below 75c to achieve the advertised power figures. A high flow intake system  is highly recommended and is required to meet the advertised power figures on the A4/A5/S4/S5/Q5/SQ5. For the best results, APR recommends removing the intake snow screen.

Supercharger Drive Pulley Removal Tool

RPM

The factory 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.
