If your craving more power from your Shelby GT500, Whipple has the answer. Get the industries biggest twin-screw supercharger. The new Whipple W275HPR can produce incredible power levels with stock 5.8L Shelby GT500 engines as well as highly modified engines. The revolutionary new W275HPR compressors have the ability to run nearly 30psi 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 140ci roots-type supercharger while dramatically lowering supercharger discharge temperatures and power consumption (hp). The W275HPR is available in a “tuner” series, which allows engine builders, custom tuning shops and others to build their masterpiece. If you want the best of the best, the Whipple W275HPR is just that.
