Supercharger Pulleys
Supercharger pulleys control the rotor speed of the supercharger relative to the engine crankshaft. Smaller drive pulleys or larger idler pulleys increase rotor speed, raising boost pressure and power output. Supercharger pulley upgrades are one of the most cost-effective modifications for factory supercharged vehicles. Popular Supercharger Pulley Upgrades Popular supercharger pulley upgrades include overdrive supercharger nose pulleys that directly drive the rotor faster, idler pulley upgrades that add tension and accommodate belt routing for larger pulley configurations, underdrive crankshaft pulley kits that reduce accessory drive parasitic drag, and complete pulley kit packages that include the supercharger nose pulley, idler, belt, and all required hardware for a complete swap. How much boost does a smaller supercharger pulley add? The boost increase from a smaller supercharger nose pulley depends on the size reduction and the base rotor speed of the supercharger. Typically, re...
