W140AX 2.3L Twin-Screw Supercharger Tuner Kit

The Whipple WK-2001TB is a premium supercharger tuner kit engineered for the 2001-2004 Ford F-150 Lightning and Harley SVT trucks equipped with the 5.4L engine. This kit showcases Whipple's W140AX 2.3L twin-screw supercharger, recognized as the largest and most efficient unit available for these applications. It's designed to deliver substantial power increases, suitable for stock configurations and heavily modified engines, with the capability to achieve up to 25lbs of boost when complemented by necessary engine modifications. This direct bolt-on system significantly reduces supercharger air temperatures and parasitic horsepower draw compared to factory Eaton roots-type superchargers. The tuner kit includes essential components for 11-13 lbs of boost, such as a large-mouth inlet casting and a high-flow cold-air intake system featuring an S&B True Flow filter. It accommodates both factory and aftermarket throttle bodies, requiring no modifications to the firewall or hood for installation. The kit is 50-state emissions legal and emphasizes OEM quality and appearance. Key specifications include an 8-25 psi boost range, depending on the crank pulley used (7.5" or 9"). It features a billet oversized bypass valve and is internally lubricated, eliminating the need to tap the oil pan. This system does not include a fuel system, programmer, or tuning; a custom tune performed locally is required after installation. The kit comes complete with all necessary parts and hardware for a straightforward installation, and its top-mount design ensures cooler operation.
