      Is this a complete kit, or is it most kits (Procharger D-1) you have to buy lots of other parts to make it functional.

      • This kit will come with everything you need in order to have a proper install. You will not need to purchase any other parts.

      With this kit is it dangerous to the engine itself? Is upgrades such as forged rods and pistons required or just a recommendation?

      • This Whipple Supercharge System will come pre-calibrated for use on a stock motor set-up meaning it is completely safe on a bone stock motor. However, to extend the life of the vehicle and increase overall reliability, It would not be a bad idea to consider upgrading some of the internals of the motor like rods, pistons, rotating assembly, ect.

      Will this work on a 2014 gt? Description says 2011 - 2012

      • The Whipple W140AX 2.3L Supercharger Kit will only work with the 11-12 Mustang GT models that are equipped with the manual transmission. This kit will not work with 13-14 GT models.

      Really Interested, but concerned about drivability, I have a 2011 GT with basic bolt ons(Longtubes, Xpipe, Catback, 355s...) To your knowledge would there be any change required to my set up..

      • This Whipple W140AX 2.3L Supercharger Kit will come with everything require for installation on a stock vehicle. Since you have some aftermarket bolt-ons, this kit will require a custom tune. Additionally, we would highly recommend an upgraded clutch to ensure it can hold up with all the additional torque.

      What strut tower brace works on a 2014 GT with the Whipple Supercharger? How much weight does this unit add? So you offer a kit for a 2014 GT with automatic trans? Thank you for your answer and Merry Xmas!

      • The Ford Boss 302 Strut Tower Brace, item # 53686, ( will be able to clear the Whipple Supercharger. The unit itself will weigh approximately 40 lbs. We do not offer the Whipple Supercharger for an automatic transmission at this time.

      Will a 2004 supercharger off a terminator cobra work on a 2011 gt? Just the blower itself. I pulled it off a cobra in a pick and pull. (Extremely lucky) I can buy all everything else later. Just trying to save money. 1 answer
