    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

    The stage 1 has 355 HP and 220 TQ but, the stage 2 has 345 HP and 220 TQ so what's the difference from the two superchargers and why is the stage 2 more than stage 1 but has less HP?

    Anon

    Is this the gen 3 top end (compressor) or the gen 2?

      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.
