APR Tuning Supercharger Drive Pulley - Bolt-On (Gen2)
Vendor: APR Tuning
APR Tuning’s supercharger drive pulley upgrade dramatically increases 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.
The 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 bolted-on fitted to the factory supercharger unit on Gen 2 models.

Supercharger Crank Pulley [**required]
Required for installation along with the bolt-on drive pulley on the Gen2 platform, 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. Upgrading both the supercharger drive and crank pulleys results in the factory supercharger spinning ~26.4% faster than stock. Use of the dual pulley configuration requires belt# RS100002.
