Description

APR MS100135 Supercharger Drive Pulley Upgrade

The APR MS100135 Supercharger Drive Pulley Upgrade is designed for those looking to enhance the performance of their Audi or Volkswagen vehicles. This precision-engineered component reduces the diameter of the factory supercharger pulley from approximately 63.25mm to 57.75mm, resulting in a ~9.5% increase in supercharger speed. This increase translates to a significant boost in horsepower and torque throughout the entire RPM range, optimizing the engine’s output.

Construction and Finish

Manufactured from high-quality billet stainless steel, the MS100135 pulley is CNC machined for precise fitment and durability. It features an e-coated black finish that not only provides a sleek, OEM appearance but also enhances corrosion resistance, ensuring longevity in various driving conditions. Weighing in at just 2 lbs, this pulley is lightweight yet robust enough to handle the demands of increased supercharger speeds.

Installation Notes

The MS100135 is designed to be press-fitted onto the factory supercharger, making installation straightforward for those with mechanical expertise. It is recommended to pair this pulley with APR’s Stage II Pulley ECU Upgrade to ensure the engine management system can accommodate the higher supercharger speeds, maximizing performance gains. For optimal results, consider combining this upgrade with APR’s Ultracharger Throttle Body Upgrade in a dual pulley setup, which alleviates inlet restrictions and further enhances power delivery.
