For more information, visit www.P65warnings.ca.gov.The APR Supercharger Drive Pulley Upgrade (MS100135) is a key performance component for the Audi 3.0 TFSI engine. This upgrade dramatically increases horsepower and torque by reducing the diameter of the factory supercharger pulley, thereby increasing the supercharger's rotational speed.
This pulley decreases the factory diameter from approx 63.25mm to 57.75mm, resulting in the supercharger spinning approximately 9.5% faster. This yields a healthy and broad increase in horsepower and torque across the entire RPM range when paired with the required APR Stage II Pulley ECU Upgrade. The pulley is precision CNC-machined from billet stainless steel, e-coated black for an OEM aesthetic, and is press-fitted to the supercharger. When combined with the APR Crank Pulley and Ultracharger Throttle Body Upgrade, this pulley helps the system achieve exciting new levels of power.
Features:
-
Massive Performance Gains: Spins the supercharger approximately 9.5% faster than stock for significant torque and HP gains when properly tuned.
-
Optimized Size: Features a 57.75mm diameter (reduced from 63.25mm factory size).
-
Premium Construction: CNC-machined from durable billet stainless steel for superior strength and longevity.
-
OEM Appearance: E-coated black for an attractive, yet discreet, OEM aesthetic.
-
Tiered Upgrade Path: Allows for multiple levels of performance, with maximum potential unlocked when combined with the APR Crank Pulley and Ultracharger Throttle Body Upgrade.

(1) APR Supercharger Drive Pulley (57.75mm, Billet Stainless Steel)
Important Note: Specific APR Stage II Pulley software is required to maximize output and ensure proper engine management. This part is only for use with pressed-on factory pulleys. If your vehicle uses a bolted-on pulley, use part number MS100139. The factory pulley requires removal tool MS100025. A new belt is mandatory: use part number RS100001 with a factory crank pulley or RS100002 with an APR crank pulley.
