Spinning the supercharger faster yields increased boost pressure throughout the RPM range, resulting in increased horsepower and torque throughout the powerband when paired with Stage 2 Performance Software. 034Motorsport's Supercharger Pulley Upgrade is meant for use with Stage 2 Performance Software, and is engineered to keep the Eaton TVS 1320 Supercharger within its maximum recommended supercharger speed with a 7,200 RPM redline.
