Description
Enhanced Supercharger Drive System. The 8-Rib Supercharger Drive Upgrade significantly improves belt traction and stability, enabling higher boost levels and increased horsepower. It is designed to replace the factory drive system without compromising the automatic belt tensioner, ensuring reliable performance for boosted Mustang GT engines. This upgrade is essential for enthusiasts aiming to maximize their vehicle’s power output while maintaining system durability.
Construction and Appearance. The upgrade kit includes precision-machined pulleys, spacers, and hardware crafted from high-quality materials to withstand increased loads and heat. Components feature a machined, durable finish designed to maintain integrity under high-stress conditions typical of forced induction applications.
Installation. Installation requires specialized tools such as a 17mm hex impact driver and a crankshaft damper puller/installer. The process involves removing OEM pulleys and requires moderate mechanical skill, but no drilling or permanent modifications to the engine are necessary.
Application. Specifically engineered to fit Mustang GT models from 2018 through 2023, this upgrade is not emissions legal for street use and requires complementary modifications including custom ECM tuning and fuel system enhancements.
