        5 2018 GT - AlexB Installation Time: Shop Install Installation Cost: $1000+

        Well Worth the $$$

        I purchased this product and I recently had it installed at a shop that specializes in installing superchargers. I completed the install with a Lund Racing tune and my car made 700whp on the dyno. If you're looking for just raw power this is the way way to go.

        5 2018 GT - Joe Installation Time: Weekend

        Worth every penny!

        Most complete kit ever imaginable ( Everything and I mean everything is provided). It took the weekend to install with the help of a very easy to follow set of instructions. For tuning I turned to Lund who provided a base tune and revisions once I provided them with a data log. The car runs amazing! Tons of power and everyday drivability.

        5 2018 GT - DaveR Installation Time: Shop Install Installation Cost: $1000+

        Very excited!

        I knew the kit was "complete" with everything needed for the installation, but it really did pass my expectations! Unbelievable quality and build! Can't wait for the VP 93 to come in so I don't have to run with Illinois winter fuel on the dyno. Initial driving impressions are amazing and really looks factory under the hood. 5star!!!

      5 Top Rated Questions

      Can the GT Performance Pkg Strut tower cross brace still be used after this install? I have a Convertible Premium GT 10 speed auto with Magna-ride and I really want the brace to stay. I'm also considering ProCharger for the same reason.

      • The Stage 2 Whipple W185AX 3.0L Intercooled Supercharger Kit will require the removal of your performance package brace for proper clearance.

      Does this kit include a cold air intake?

      • The Stage 2 Whipple W185AX 3.0L Intercooled Supercharger Kit does not include an aftermarket cold air intake.

      Helpful (9)

      If the rest of the car is kept stock performance wise, besides a tune, what kind of 0-60 numbers can I expect from this on a manual 18 GT?

      • This is hard to determine as it will be based off of available traction, and the driver just as much as the mods done. Even stock there can be a wide range of 0-60 times based on these two factors alone.

      The tomahawk flash that is supplied with the supercharger, is that the same as the Whipple tune?

      • This comes with the Tomahawk tool, and tuning for stock applications.

      About how much hp to the wheels will this supercharger put down with the whipple tune?? Rest of car stock

      • Whipple does not list an estimate in terms of RWHP following the installation and a tune. With that being said this kit has seen gains of at least 815+HP and 640 of torque with use of 93 octane fuel.
