APR 3.0T TFSI Supercharger Drive Pulley Upgrade - Bolt On
In stock and ready to ship!
This listing is for the gen 2 Simos 16.x bolt-on supercharger pulley. If you have the gen 1 8.x Simos ECU, you will need to use this kit instead. If you need assistance identifying which ECU you have, please feel free to contact us.
NGP presents the APR 3.0 TFSI Supercharger Bolt-on Drive Pulley Upgrade.
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.
Supercharger Belt - For use with an APR Drive Pulley & an OEM Crank Pulley PT# RS100001 is sold separately.
APR Stage II ECU Upgrade:
APR’s Stage II ECU Upgrade is designed for use with each pulley upgrade and only needs to be purchased once. The upgrade builds upon the APR Stage I ECU Upgrade, reconfiguring the engine management system to work in conjunction with the higher boost pressure and airflow levels achieved by spinning the supercharger faster. The Stage I ECU Upgrade is required to purchase the Stage II ECU Upgrade. See Info Here
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.
Supercharger Belt - For use with an APR Drive Pulley & an APR Crank Pulley RS100002 is sold separately.
Dual Pulley Upgrade Note:
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.
Tech Notes: 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 Coolant Performance 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.
