Supercharger Overdrive Pulleys
Overdrive pulleys allow you to adjust the amount of boost your RB Innovations nitro supercharger produces. The stock pulley that comes with each supercharger provides a 30% overdrive. The 50% overdrive pulley will increase the speed at which the turbo impeller spins. When the speed of the turbo impeller is increased, the amount of boost produced by the supercharger is also increased.
