The APR MS100133 Supercharger Crank Pulley Upgrade increases the diameter of the factory pulley from ~162mm to ~187mm, which in turn spins the supercharger ~15.4% faster. This results in a larger bump in horsepower and torque across the entire RPM range. The pulley retains the factory harmonically balanced crank pulley and bolts on top of the existing unit.

APRs Supercharger Drive and Crank Pulley Upgrades dramatically increase horsepower and torque by increasing the rotational speed of the factory supercharger. APRs Stage II 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 Supercharger and Crank pulleys are sold separately, allowing for multiple levels of performance, each of which builds upon the other.
