If your craving more power from your Shelby GT500, Whipple has the answer. Get the industries latest, most efficient twin-screw supercharger. The new Whipple W175HPR can produce incredible power levels with stock 5.4L Shelby GT500 engines as well as highly modified engines. The revolutionary new W175HPR compressors have the ability to run nearly 25psi of boost (engine modifications required) for unheralded performance. A simple pulley change in minutes will allow you to step up or down for street or race applications allowing customers the ability to dial in their Shelby.


This direct bolt-on replacement system gives you the ability to run far higher boost levels than the factory 122ci roots-type supercharger while dramatically lowering supercharger discharge temperatures and power consumption (hp).

The Whipple Shelby GT500 kit not only offers a better supercharger, but the potential to have one of the fastest, most powerful street machines on the road today.

  • 3.25" Supercharger Pulley (17 psi)
