Who needs a Shelby GT500 anyway?
Ford recently pulled the wraps off of the 2020 Shelby GT500, the most powerful Mustang ever produced from the factory courtesy of a 5.2-liter 700 horsepower supercharged V8. Although pricing hasn't been released yet for the GT500, expect a significant increase over the Shelby GT350's price tag of $59,140.
Alas, the GT500 won't have a manual option. However, if you want a 700-hp Mustang but can't stomach the idea of letting a computer shift gears for you, Ford now has an alternative solution. Roush is offering its factory-backed supercharger kit for the 2018 and 2019 model year Mustang GT.
The stock 5.0-liter Coyote V8 already produces a healthy 460 hp and 420 lb-ft of torque going to the rear wheels through a six-speed manual or 10-speed automatic at a cost of $35,355. If you are willing to spend $7,699 on top of that, you can add a Roush TVS2650 2.65-liter supercharger to bring the output up to 700 hp and 610 lb-ft of torque (on 91-octane fuel). The kit is compatible with both manual and automatic GT models and also includes new ports, intercooler, radiator, fuel rails, and a bigger throttle body.
Perhaps most impressively, this kit retains the three-year/36,000-mile factory warranty when installed by a Ford dealership or ASE-certified technician. There will undoubtedly be some labor costs involved but you can essentially get a 700 hp Mustang for around $43,000 (before labor). You simply need to find someone to handle the 12-hour install.
Roush says the kit is compliant in all 50 states but there is one small caveat - the kit is only compatible with 2018 and 2019 GT models, not the special edition Bullitt. The other big disadvantage we see here is that the kit doesn't do anything to upgrade the suspension or brakes. Opting for a base Mustang without one of the optional Performance Packages and pumping it up 700 hp sounds like a recipe for an accident. We suggest opting for at least the Performance Pack 1, which may slightly ruin the value proposition.
