Vortech 8-Rib Supercharger Drive Pulley; 3.60-Inch

Increase Or Decrease Supercharger Boost Levels. An underdrive pulley is a quick and effective means of increasing or decreasing your supercharger’s boost production in relation to engine RPMs, changing the speed at which the supercharger’s impeller spins. A smaller pulley tends to generate more boost, spinning faster at the same engine RPMs, while a larger pulley produces less boost, requiring more movement to make a full rotation of the impeller. If you’re looking to alter the boost level produced by your Vortech supercharger, consider swapping out your Supercharger Drive Pulley. 

Increase Your Supercharger’s Efficiency. The key to making reliable power with any centrifugal supercharger system is to ensure a stable connection between the crank and the supercharger drive pulley. With a drive belt that’s unable to hold up to the power demands of your application, you may experience belt-slip at higher RPMs, a condition in which the drive belt skips across the supercharger drive pulley due to lack of adequate grip. If your Supercharged Charger is facing a power-robbing belt slip, consider upgrading your drive system to a higher rib count using this Vortech 8-Rib Supercharger Drive Pulley, accompanied by an 8-rib drive belt and the supporting accessory pulleys. 

Durable Construction. Vortech supercharger drive pulleys feature a premium, CNC-machined 6061 T-6 billet aluminum construction for maximum strength and reliability even in the most demanding applications. In addition, the 8-rib grooves help promote greater surface traction to reduce premature wear over use. 

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

Application. This Vortech Charger 8-Rib Supercharger Drive Pulley is a universal-fit product applicable to 2011-2023 Dodge Chargers equipped with a Vortech supercharger system.
