FINALLY A BETTER OPTION

If your craving more power from your Lightning or Harley truck, Whipple-Ford Racing has the answer. Get the industries largest, most efficient and latest designed twin-screw supercharger. The new Whipple-Ford Racing system can produce incredible power levels with stock 5.4L Lightning engines as well as highly modified engines. The revolutionary new W140ax compressor has the ability to run nearly 25lbs of boost (engine modifications required) for unheralded performance.

This direct bolt-on replacement system dramatically lowers supercharger air temperatures and power consumption (hp) versus the factory Eaton roots-type supercharger. The complete bolt-on system comes with all the necessary parts for 13lbs of boost and includes a large mouth inlet casting, high-flow cold-air intake system with massive S&B True Flow 9” filter and all as the necessary parts for a simple installation. The Whipple-Ford Racing system accommodates both factory and aftermarket throttle bodies and there’s no need to clearance the firewall or hood in anyway.

Other companies make false claims and inaccurate judgments regarding supercharger efficiency and kits. It’s a simple fact that the Whipple Supercharger produces more air per rpm at lower temps and lower parasitic losses.

Up to 175HP gain on Lightning engines. More available with high performance engine modifications.

Largest displacement screw compressor available for Lightning’s and Harley’s.

More air flow at lower compressor speeds when compared to competition
