        Much needed replacement

        Thanks guys! This water pump fit perfectly, a little costly but it prevented my Mustang from overheating! Had to downgrade to the 3.0 version, ( I have a 5.0) but it works great!

      What’s the difference between Whipple supercharger stage 1 and stage 2? How does stage 2 make more power than stage 1?

      • The items included in the stage 2 kit would be different than this kit here. The stage 2 would have an upgraded throttle body, fuel pump, and a different size pulley than this kit here. With those added parts and the tune for this kit, the performance gains will be more.

      Under features and description....what do you mean by expert installation? Will this kit void the original factory warranty of my vehicle?

      • With the expert installation, we advise having a shop do the install. In regards to the warranty on the vehicle. More than likely it will void the warranty, but we highly recommend checking with your dealership to confirm.

      Can the stage 1 be tuned to run on 91 octane. That's what is most available at our pumps here in Wisconsin as a premium fuel with no ethanol. Will the hp and torque numbers take a hit with 91 octane?

      • Yes, this can be used with 91 octane. Advertised gains will be reduced when using non-93 octane.
