    Craving More Power? Is your factory Eaton Supercharged Shelby GT500 not making enough power for your needs? Then upgrade to a W175AX 2.9L Twin Screw Whipple Supercharger compressor for big power gains from your DOHC 4-valve 5.4L GT500 Mustang.

    W175AX 2.9L Upgrade Kit. This Whipple W175AX 2.9L Twin Screw compressor is a direct bolt-on replacement that gives you the ability to run far higher boost levels than the factory 2.1L roots-type supercharger will allow, while dramatically lowering supercharger discharge temperatures and power consumption (hp).

    10 - 25 psi. The Whipple 2.9L Supercharger will produce up to 10psi of boost with the factory supercharger pulley and can even handle a maximum 25psi of boost pressure with pulley and intake upgrades for unheralded power and performance.

    50 State Legal. Unlike the competitors, this Ford Racing Supercharger Kit is 50 state emissions legal under CARB EO# D-231-35.

    Required Upgrade. Installation of this Whipple Supercharger upgrade kit will require custom calibration of your vehicles computer (PCM) for operation (not included). AmericanMuscle recommends the use of a Handheld Tuner loaded with custom tunes.

    Application. This Black Whipple 2.9L W175AX Supercharger Upgrade Kit is designed as a direct fit performance upgrade for the 2007 to 2012 Shelby GT500 Mustangs equipped with the Supercharged 5.4L DOHC V-8 engine.

    Please Note: Whipple Supercharger Kits are built to order for our customers. Because of this there can be a 10 to 14 day lead time on orders.
