The APR Supercharger Pulley Upgrades dramatically increase horsepower and torque by increasing the rotational speed of the factory supercharger. APRs Supercharger Drive Pulley decreases the diameter of the factory supercharger 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.
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.
