    Will this fit a coyote swapped 1999 mustang? If it cant, what supercharger will be able to fit?

    XavierC

    • This Whipple Stage 2 Supercharger Kit will work on the coyote swapped mustang as long as the 5.0L is from the 15-17 models. You may also need to get a larger hood to allow for clearance.

    Whipple stage 2 has 245HP and whipple stage 1has 355HP. Why is the stage 2 more expensive but putting out less HP??

    Anon

    • While checking with Whipple, we did discover that the Stage 1 supercharger will give your car 650 HP to your rear wheels. The stage 2 will give you 680 HP to the rear wheels.

    Is there a way to get the stage 2 kit with a color finish?

    BrettD

    Is a fuel pump voltage booster required with the stage 2 kit?

    BrettD

    So, I've been told that the Roush S/C Phase 2 is "not recommended" for use in cars with adaptive cruise control. That blew my mind (its like we're back in 1970 where people tell you you can't have power windows or a/c if you are going to have a performance car). WHY would that be the case. So, if Roush is going to disable my ACC, is this the same case on the whipple, because, I'm not giving up ACC. Period.

      Whipple stage 2 performance

      I got the kit that is described here and put it on my 2015 Mustang GT only to find that the tune that they provided for some reason has a dead spot in it I have spent countless dollars trying to figure out what the problem is why it has a sputter and when calling Whipple Factory itself it seems that nobody wants to help me solve my issue. At a price of $14,500 Canadian for the Whipple stage 2 going on a brand new car I was kind of let down so buyer beware.
