2001-2004 Ford F-150 Whipple W175AX 2.9L Competition Supercharger Kit

This Whipple W175AX 2.9L twin-screw supercharger system is purpose-built for the 2001-2004 Ford F-150 (2.9L supercharger swap), delivering up to roughly 250 horsepower over the factory setup, with boost approaching 25 psi given the right supporting modifications. Every system is engineered, machined, and assembled in-house at Whipple's Fresno, California headquarters as a complete, matched package — not an assortment of parts pieced together.

This W175AX 2.9L twin-screw compressor is built to add up to roughly 250 horsepower over the factory setup, with a high-flow intake and a 9" filter. An oversized billet bypass valve manages boost. Internally lubricated — no oil pan tap required.

Competition use only, not street legal.

Race/off-road use only. This kit is not CARB certified and is not legal for street use on pollution-controlled vehicles in any state including California.
