Hennessey performance recently took a 2020 Ford Mustang Shelby GT500 onto its dyno while also putting it to the test along its racetrack.
Ford claims that the supercharged 5.2-liter V8 engine of the Shelby GT500 is good for 760 hp and 625 lb-ft (847 Nm) of torque at the crankshaft. Running at full steam on Hennessey’s dyno, the gorgeous blue car pumps out 708 hp at roughly 7,300 rpm and 589.5 lb-ft (799 Nm) of torque at 4,100 rpm at the rear wheels.
The driver hits a speed of around 146 mph on a straight section of track, which he says is already on par with many of Hennessey’s top modified vehicles. For what it’s worth, Ford limits the GT500’s top speed to 180 mph.
Hennessey is currently working on a series of upgrade packages for the Shelby GT500 that will be offered in 850 hp, 1,000 hp, and 1,200 hp guises. Among the modifications Hennessey will use to achieve these figures is a new 3.0-liter supercharger (larger than the 2.65-liter unit found standard), high-flow catalytic converters, a new pulley and belt, upgraded fuel delivery system, new air induction system, an intercooler upgrade, New pistons and connecting rods, as well as a strengthened seven-speed dual-clutch transmission.
