Review & Installation Video

Unprecedented 90% Increase in Power. The Whipple Stage 2 Supercharged Kit is a comprehensive, high-quality, industry-leading package that runs 10 to 11psi and instantly ramps up your Mustang GT’s power levels by as much as 90%. A huge, low-restriction front-feed twin-screw supercharger design, billet 132mm electronic throttle body, high-flow fuel injectors, air-to-water intercooler, and included OBDII flash tool make this the most powerful system you get that is emissions-legal in all fifty states.

Tuning Required. Once the Whipple Supercharger Kit is fully installed, PCM tuning is needed to ensure that engine performance is optimal. Whipple includes everything needed to install a newly calibrated engine tune so you get the biggest, most-reliable performance gains possible.

Top-Notch Build and Technology. The list of quality components included in the Whipple Supercharger Kit is almost as massive as the performance gains it produces. From the industry-leading 2.9L Whipple supercharger and giant 2L charge-cooling system to the billet 132mm Roval electronic throttle body and 72lb/hr fuel injectors, everything has been engineered to provide reliable, long-lasting power improvements.

Complete Installation Kit. Whipple includes everything needed to install their ultra high-performance supercharger kit and reprogram your Mustang’s engine management to capture every last ounce of power. Installation takes one day and should be performed by a professional or someone with mechanical expertise. The included Flare software also allows for wheel/axle changes.

One-Year Whipple Warranty. Whipple provides a limited one-year warranty on this Supercharger Kit.

Application. The Whipple Stage 2 Supercharged Kit is engineered expressly for Ford Mustang GTs from 2015 to 2017.

What are the recommended parts that should be changed? I know it’s best to swap the factory clutch but what else would increase the longevity of the car? Also what other parts would increase rwhp? 1 answer

To clarify, this is a complete kit so in regards to getting that supercharger to run, Whipple provides everything including the tune. With that being said, to get the rest of your Mustang ready for this installation, a clutch would definitely be necessary to handle those extra horses. Then from here, you can look into getting your suspension ready. I would suggest to look into anti-wheel hop kits, anti-roll kits, and maybe a sway bar depending on what driving you are looking to do. Lastly, getting some bigger tires in the rear so you have more rubber to grab the pavement with all that horsepower would be a good idea.

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.
