Vortech 10-Rib Supercharger Pulley; 3.33-Inch

Upgrade Your Supercharger’s Drive Belt System. The factory 4-6-rib supercharger drive belt system included with your Mustang’s Vortech supercharger is a reliable and efficient system for mild to moderate power production. However, it may be insufficient in high-horsepower, high boost applications. Unfortunately, when the drive belt system is overwhelmed, belt slippage occurs between the supercharger drive pulley and the drive belt, causing a loss of energy transfer from the crankshaft to the supercharger head unit. This energy loss translates to lower compressor speed, reduced boost, and limited power. If you’ve been experiencing power-robbing belt slip, consider upgrading your supercharger drive belt system with the help of this Vortech 10-Rib Supercharger Pulley. A 10-rib drive belt system drastically reduces belt slip with double the surface area, allowing for efficient supercharger operation. 

Alter Your Mustang’s Boost Curve. Centrifugal superchargers are mechanically-driven, relying on the motion of the crankshaft to rotate the supercharger drive pulley/impeller and create boost. They’re also effortless to fine-tune for this reason, with a quick supercharger drive pulley swap drastically altering the boost curve. With a smaller diameter pulley, boost comes on quicker and harder at low RPMs, though the rotational torque applied to the supercharger compressor is far lower. The inverse also applies to a larger pulley: rotational torque is increased, while boost is lowered across the RPM range. 

Durable Construction. Vortech’s Supercharger Drive Pulleys feature durable, CNC-machined, 6061 T-6 billet aluminum construction for superior durability and strength. Additionally, the CNC machining process creates precise grooves, engaging perfectly with the supercharger drive belt’s ribs for increased friction and reduced belt slip. 

Warranty. A 3-year warranty protects this product from manufacturing defects. 

Application. This Vortech Mustang 10-Rib Supercharger Pulley fits all Ford Mustangs.
