1999-2000 Ford F-150 SVT Lightning / Harley-Davidson Whipple W140AX 2.3L Competition Supercharger Kit

This Whipple axial-entry W140AX 2.3L twin-screw supercharger system is purpose-built for the 1999-2000 Ford F-150 SVT Lightning / Harley-Davidson, delivering up to roughly 175 horsepower over the factory Eaton roots-type supercharger, with boost ranging roughly 8-25 psi depending on the pulley selected. 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 axial-entry W140AX 2.3L twin-screw compressor is built to add up to roughly 175 horsepower over the factory Eaton roots blower, with a large-mouth inlet and an S&B True Flow 9" filter. An oversized bypass valve manages boost across a roughly 8-25 psi range depending on the pulley selected. Internally lubricated — no oil pan tap required.

Competition/race use only, not street legal. Boost level and output depend on the pulley chosen and the supporting build.

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. It does not include injectors, a tuning device, or PCM calibration — it's built for customers running their own custom fueling and tuning setup.
