    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.

    What does this kit include other than the head unit? Do i reuse any parts off my original supercharger or does this come with everything i need ie throttle body, cold air intake, ect?

    JohnM

    • The Whipple 2.9L Supercharger Upgrade Kit is a direct bolt on replacement for the stock super charger. You will reuse your stock parts.

    If I put this blower on my 12 GT500, will I have to upgrade anything else besides the tune ?? Or can I just keep the blower on

    Steezydbricks

    • The Whipple 2.9L Supercharger Upgrade Kit will come with everything needed for a complete install with the exception of a custom tune.

    Why can I not find this supercharger in the polished finish instead of black. I have been wanting to buy one but really want the polished look.

    • At this time we would not have the Whipple W175AX 2.9L Supercharger Upgrade Kit in the polished.

    Would you recommend bigger fuel injectors? If so what size? I am running the mono blade throttle body and custom off road exhaust with the 3" pulley how much boost am I looking at running 92 octane.

    05GTHI

    • It is a good idea to upgrade the fuel injectors when installing the Whipple Black Supercharger Upgrade Kit. If you are looking to make a lot of power, we recommend the Injector Dynamics EV14 High Impedance ID1000 Injectors - 96 lb (07-14 GT500), item # 100541, (http://www.americanmuscle.com/injector-dynamics-ev14-96lb-gt500.html). If you are going with something else, you will need a EV14 model injector for your car. The amount of boost you get all depends on other applications on the car.

    Do i need to order any additional parts for a complete install kit other than the handheld tuner?

    Anonymous

    • No, you will not need any other parts in order to install this supercharger on your car. The only required part would be a handheld tuner to optimize performance. Though, upgrading exhaust and intake components will increase power.

      Extremely satisfied!

      The blower went on a 2011 gt500 with only a CAI. With a tune it has 639hp 595tq at 17psi. The blower has much more power to give but with only 91 octane that's the best I got. Still I'm satisfied with the power and with the product maybe later I will install a meth kit and I'll be around 22psi. Once again thanks to American muscle and whipple.
