Tired of belts slipping, breaking or simply being thrown off your Whipple supercharged Mustang when pushing it to the limit? Those days are now over!

Steeda's Belt Drive System for Whipple Supercharger was designed to prevent any such belt problems that are all too common during competition or just hardcore use of your Mustang. Steeda designed this belt drive package to relocate the supercharger drive off the factory 6-rib system, making it a dedicated 10-rib belt system, which drives the supercharger and nothing else. Removing the supercharger drive from the primary accessory drive serves to eliminate any and all slippage problems that can occur, including both on the initial tip in and under full load.

The standard accessories are driven by a Steeda underdrive pulley for even more power and reduced accessory load. Our 10-rib system is available in boost levels of approximately 11psi to 17psi on a Gen 1 Whipple system and approximately 13 to 19psi on a Gen 2 Whipple system with no slippage under any conditions, and no throwing or breakage of the supercharger belt.

The package includes a new supercharger snout, billet pulleys, billet mounting plates, 2 new belts, and a heavy-duty belt tensioner. Although we recommend a Steeda hood, it only takes a minor modification to fit the system under your stock hood. Full installation instructions, including to the procedure for measuring stock hood clearance, are included.

Already own a Steeda Belt Drive and want to change boost levels? Take a look at our separate lower boost pulley kits.

Important Note: Stated boost levels are estimates only based on GEN 2 Whipple superchargers and will vary widely depending on numerous factors including but not limited to: Exhaust configuration, cylinder heads port configuration, camshafts, geographic elevation, engine compression, throttle body size, boost gauge accuracy, and other factors beyond the control of Steeda Autosports. Use numbers provided for guidance only.

In general, cars with large cams, cylinder heads, etc will have slightly lower boost levels.
