The star of the Shelby GT500 show is a 2.65-liter, roots-type supercharger bolted to the recently overhauled 5.2-liter V8 engine Ford uses in the Shelby GT350. The supercharger is nestled into the valley between the V8’s cylinder banks to keep the GT500’s center of gravity as low as is possible, and is fed by an air-to-liquid intercooler and a redesigned front end that maximizes the amount of atmosphere making its way into the engine bay.
Power is prodigious, amounting to 760 horsepower at 7,300 rpm and 625 lb.-ft. of torque at 5,000 rpm. The engine’s redline is a lofty 7,500 rpm. That’s 234 more horses and 196 lb.-ft. more torque than the Shelby GT350 makes.
Ford says the new Mustang Shelby GT500 accelerates to 60 mph in 3.3 seconds, runs the quarter-mile in 10.7 seconds, and is governed to a top speed of 180 mph.
