Description

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.

650 RWHP out the Box

It's genuinely a totally different car when you press down on that peddle. Drives like stock when cruising, but when you go, you goooooo. I ran 3 Dyno pulls post install and was at 635,640,and 650rwhp with the Whipple Tune. If you want instant power this is the way to go, just expect on buying some new tires to avoid spinning.

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.
