If you're craving more power from your Shelby GT500, Whipple has the answer. The all new bolt-on supercharger system is the first and only 50-state legal supercharger upgrade available today. While the GT500 pumps out an astouding 760HP, the small supercharger, when coupled with the severely undersized intercooler and inlet system lacks ability to safely make more power on 91/93 octane. The massive 3.8L Gen 5 twin-screw supercharger is 43% larger in displacement and features the patented dual core, dual pass intercooler for incredible, uncomparable cooling capacity.

Each system features the billet, 132mm throttle body, Whipples unique 145mm cold air intake system with the oversized air filter for all the air your engine could use. While the air intake system is industry leading, the real magic comes from the patented intercooler system. The discharged air goes through each intercooler two times, giving the system overall double the capacity of the stock IC core. Even better, the Whipple dual cores feature dual 3/4" ID and dual 3/4" outlet for the intercooler water, allowing nearly twice the water flow of the stock IC core. Did we mention, the supercharger lid is made of 6061-T6 billet for added strength while clearing the factory strut tower brace and hood vents.

The industry leading, record breaking 3.8L has dominated in every race class its been legal, destroying the competitions superchargers. With over 2000HP capacity, the GT500 3.8L comfortably makes an astonishing 1035HP on 93 octane fuel with an 100% stock engine and exhaust, with only 15psi of boost. That's a 275HP gain over the stock system, while being 50-state legal!

The Whipple upgrade system includes a HP Tuner RDT flash tool for easy calibration delivery and enhanced data logging capacity, along with the 4 credits required for flashing. Each Whipple system comes with new motor mount brackets to fit under the stock hood, billet idler plate and idler pulleys, intercooler vent system, SC belt and all the necessary hardware for an easy installation.

Sincere thanks to Paul Faessler and all the staff at Paul's Automotive Engineering for all their exceptional and professional knowledge, skill, experience, hard work and dedication. I could not have won the National Championships without you.

Best engine builder bar none for ANY ford is Paul’s Automotive Engineering in Blue Ash, OH. He does tons more than just engine stuff but if you’ve been racing these cars for any sort of time you know Paul and Brian Faessler. If you need a shop for anything Mustang, that’s the place. Been building my engines for over a decade. After several failed attempts from other shops (including names you would know) and consistent failures I went to PAE. I have never been let down from any single engine he’s built yet. My first one lasted well beyond what would be considered a rebuild interval given the abuse I put them through!

I can vouch for Paul and his team. After looking all over the Southeast for someone to upgrade my '15 GT, I found Paul's shop in Cincy and decided to take a chance and ship my car 500 miles to them. I have ZERO regrets. 

Almost 4 years later (time sure flies) the car still runs flawless. I would not hesitate to trade with them again.
