    More Horsepower! The stock Coyote powered GT Mustang came with an awesome 435 Horsepower and 400 lb/ft of Torque from the factory, but after installation a ProCharger-equipped 5.0L S550 Mustang can make 65-70% or more horsepower at the flywheel. Thanks to the industry's coolest charge air temperatures, the unmatched power gains are delivered with maximum reliability and everyday drivability.

    High Capacity Intercooler. If you have the desire to continue modding your Mustang even after adding a ProCharger Supercharger, then this is the kit for you. The air-to-air intercooler included with the Stage II Kit has a higher capacity than the High Output (HO) Kit. This Stage II kit will accommodate additional modifications as you continue to transform your Mustang into the highest horsepower beast possible.

    Complete Kit. The ProCharger Stage II Intercooled System comes 100% complete and includes ProCharger self-contained supercharger, air-to-air intercooler, Deatschwerks 95 lb/hr (1000cc) Fuel Injectors, JMS PowerMax Fuel Pump Booster, intercooler tubing, brackets and a nGauge handheld tuner.

    Application. This ProCharger Stage II Intercooled Supercharger System is specifically designed for use on the 2015-2017 GT Mustang equipped with the 4V 5.0L Coyote V8 engine.

    Technical Note. This Complete Supercharger Kit is designed to be used on stock applications, as Procharger will only provide a tune for the stock motor with stock exhaust or most aftermarket axle-back and cat-back exhaust systems. If your vehicle is no longer stock and has been upgraded with an aftermarket throttle body, cold air intake, headers, off-road mid-pipe, etc..., Procharger will not be able to provide a tune for your modifications. For modified vehicles, it would be best to purchase a Tuner Supercharger Kit so you can have a local Dyno Shop custom tune your vehicle with your aftermarket upgrades.

    Please Note. Procharger Supercharger Systems are built to order for our customers and accordingly, we require you to submit additional information about your vehicle using this form. Because of this there is a 14 day lead time on orders once your information is received.

    Once the Customer Information Form is filled out, please email it to with your Order Number in the Subject line, so the order can be processed.

    How much hp/tq can I actually expect to see to the ground. The only other thing I have is the borla catback exhaust. And also what else could I purchase to make even more power?


    • Depending on the head unit, you'll put down 600-750. If you do the direct bolt on, it will be a 9psi system making in the area of 675 to the flywheel. Custom tunes and a head unit swap can get you more. You have to get the head unit upgrades direct from ProCharger. The head units will ramp up your PSI... but anywhere above 10 PSI and without engine mods, you'll be playing with a hand grenade if you don't know what you're doing.

    Your staff have given 3 varying answers on hp gain as well as contradictory statements on whether this kit is helical. Can someone knowledgeable provide an accurate answer to both of these questions?

      Procharger Stage 2 install

      I installed the stage 2 kit in my garage by myself in a day and a half. I took my time and it went smooth with no issues. The instructions are very easy to follow and the kit fit perfect as advertised. The driveability under normal conditions is factory smooth but hit the throttle hard and the car has amazing power. I'm very happy with the Procharger

      Best for Daily

      (2015 Roush Stage 2) I bought his kit when it was more that $1000 less (must have been a sale or something) so it was an amazing deal. I really wanted a 2.9L Whipple but this is seems to be better for a daily driver and you can still tune and pulley it up to Whipple HP numbers, if you want. Only complaint was a bent MAF extension cable pin. I did a lot of supporting mods before this and I would say at a minimum you need: 800 hp half shafts (DSS or FP), billet OPG and crank sprocket, and I also went with a ATI Super Damper and Procharger ATI pulley. That's minimum, but I did a bunch of other stuff too and continue to upgrade (clutch, drive shaft, etc.). I would also highly recommend the UPR dual valve oil catch can made for this setup. Happy tire roasting!
