    I read part of the installation instructions and it looks like a buyer should wait until after installing the supercharger before replacing the stock camshafts to see if the new camshafts are compatible, is that right?

    • A supercharged engine will have special requirements from a cam, so a supercharger cam would perform best. Final cam selection will depend on your overall build and intended usage.

    What keeps this kit from being compatible with a 2009 mustang gt?

    • The 09 GT used a different charging system than the 05-08 Mustangs. This change makes for fitment differences between the previous years.

    Do You have to use the Diablo sport tuner with this? What if you already have a tune from Bama Performance?

    • Unfortunately, Bama cannot tune for this Supercharger. You will have to use the DiabloSport Predator Tuner that is supplied in this kit.

    If you buy this Vortech Supercharger, is it possible to add an intercooler at a later date? Also will this work with a few mods such as FRPP Manifold, 62mm throttle body and shorty headers? Thanks for your help

    • yes you can! and it would go great with the mods you have on the car, and with long tube headers even better since these engines breath with them, you should make good power with this a intercooler and some other mods and the current ones you have as well, I would recommend and dyno tune for best performance

    Does this include any air-air or air-water

    • This Kit does not include an air to air or air to water intercooler. You can always add one after the kit has been installed. It may require some modifications in order for a proper install.

      If you want something that will go when given the pedal, but remain subtle when you want it to... THIS IS WHAT YOU WANT. The power is EXTREMELY noticeable, I would definitely recommend this over any bolt-ons. The install was very detailed and straightforward as well, nothing too over the top. However, this is something you would not want to rush... So take your time and enjoy the transformation of your very own 3 Valve before your own eyes!
