There’s no question that the 2020 Ford Mustang Shelby GT500 is the most powerful and quickest production Mustang that the automaker has ever concocted. Its supercharged 5.2L “Predator” V8 produces 760 horsepower and 625 pound feet of torque, nearly 100 more than the previous generation Shelby. The new Tremec 7-speed dual-clutch transmission is a first for the Mustang as well, helping the GT500 run an estimated 0-60 mph time of about 3.5 seconds and a quarter-mile in less than 11 seconds according to Ford. While the 2020 Shelby is the most extreme Mustang you can buy with a warranty, the extensive aftermarket for the famed pony car means that there are some monster Mustangs roaming the streets and strip. Thanks to a youtube clip posted by BigKlieb34, we get to see what a heavily modified previous generation GT500 is capable of at the dragway.
From the factory, the 2013-2014 Ford Mustang Shelby GT500 produced 662 hp and 631 lb-ft of torque from its 5.8 supercharged V8 engine. A Tremec TR6060 6-speed manual was the sole transmission offered for the 2013-2014 GT500, despite it’s obvious drag racing intentions. That is still a lot of power even in this age of 700 horsepower muscle cars, though it wasn’t quite enough for the GT500 owner in question.
Under the hood of this Grabber Blue GT500 sits a L&M Engines built version of the 5.8L V8, though now a 76mm Precision Turbo sits in place of the factory blower. A custom tune from Lund Racing helps to make the most of the built motor, all while allowing the GT500 to retain its factory computer. Total output is a ludicrous 2,000 horsepower at the crank, or about 1,700 horsepower at the rear wheels. That 4-digit power figure is routed through a TH400 automatic transmission that replaces the factory 6-speed, as well as a built Fab Ford 9-inch rear end out back. If it wasn’t obvious that this car is utterly nutty, the parachute hanging off the rear bumper might hint at what it is capable of.
Despite trying to replicate a NASA launch on its first pass in the video, the Shelby is able to run a 7.72 second 1/4 mile pass at 178 mph, all while picking up the nose off the launch. With how hard this muscle car leaves the line, we can’t believe it hasn’t been fit with a wheelie bar. The 2020 Ford Mustang Shelby GT500 might be a ridiculously fast car, but it would downright tame making a pass next to this high-flying speed machine.
