    Can I still use my tower brace? I have a 2008 Bullitt, will this supercharger fit under the stock tower brace? Can I use the cold air intake that came with the Bullitt or do I need to change it with the one in the kit?

    Cams, tune and hood fit Will this unit work with the Comp Cams Mother Thumper 2 cams or would I have to go back to the stock cams? Does tis unit come with a tuner and tune or would I need a to use my SCT and tune from American Muscle? Does this unit fit under the stock hood?


    • Yes it can be tuned to work with Mother Thumper 2 Cams. Yes it's equipped with a tuner package deal and No unless you prefer to use your preowned tuner and work it out with AM. Yes it will fit under stock hood easily.

    Have a 2010 GT Manual. Upgrated from stock i have a C L Cold Air Filter, Ford Racing throttle body, and ford racing Intake manifold. On the exhaust i have kooks long tube headers and kooks offload x pipe with magna flow racing mufflers will this supercharger work with the above? I'm sure the intake section might have to be removed. everything else is stock, will i have to get other parts to support the horsepower gains?


    • The Whipple Intercooled Supercharger Kit will be able to reuse all of your parts with the exception of the cold air intake.

    Can i use with stock cam ?


    • The Whipple Intercooled Supercharger Kit can be used with stock cams, however a set of cams designed for use with superchargers (blower cams) will provide significant performance increases over your stock cams.

      Incredible S/C kit

      This is an amazing mod. HUGE horsepower gains will have you well over 450 at the rear wheels. The kit is very complete and high quality. All went together very well. AmericanMuscle notes (even after I brought it to their attention) that the kit comes with a flash programmer, which is incorrect. After several calls to AM and Ford Racing I ended up having to send my PCM to Whipple. No big deal, but it'd be nice if AM would list it correctly so you know what you're getting (especially since this issue has been brought to their attention...). In any case, this thing sounds GREAT, very loud whine. It feels great and pulls like crazy. It looks great and everything fit my GT as it was supposed to. Highly recommended
