If your craving more power from your Lightning or Harley truck, Whipple has the answer. Get the industries most efficient and latest designed twin-screw supercharger. The new Whipple 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 bolt-on system comes with all the necessary parts for 12lbs of boost including, 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 system accommodates both factory and aftermarket throttle bodies and there’s no need to clearance the firewall or hood in anyway.  Using a clean sheet design, Whipple used the rear axial entry design vs the factory axial/radial version that sacrificed drastic performance. The Whipple axial entry reaches nearly 99% VE during its operation, significantly outperforming the stock supercharger.

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.
