Brenspeed Breathes 650 HP into High-Mileage 2009 Ford Mustang Shelby GT500
Since Ford shared how much power the 2020 Shelby GT500 Mustang will make, in addition to how much it will cost you, owners of the previous generation GT500 might feel it’s a good time to make some upgrades.
But what if your car has more than 100,000 miles on it? Should you really mess with its high-mileage Modular or Trinity?
Brenspeed, the Mod motor Mustang experts located in Indiana, got their hands on a one-owner 2009 Ford Shelby Mustang GT500 with 106,000 miles on it. According to the video, the car received a 2.9-liter Whipple twin-screw supercharger, in addition to a few other performance parts, and made 658 hp to the wheels on 93 octane.
