The sixth-generation Ford Mustang GT is already a quick car, but if you want it to be hair-on-fire-bat-guano-crazy quick, then we would point you toward Hennessey Performance->ke1863 outside of Houston, Texas. Hennessey’s HPE750 upgrade includes a 2.9-liter supercharger and a long list of other go-fast parts that pump the 5.0-liter Coyote V-8’s output up to 785 horsepower at 7,000 rpm and 648 pound-feet of torque and 4,400 rpm.

That’s powerful enough to do 0-60 in 3.4 seconds, the quarter mile in 10.9 seconds and more than enough to break 200 mph. To prove that last part, the Hennessey guys took a HPE750 Supercharged Mustang to the 8.5-mile high-speed oval at Continental Tire’s proving grounds in Uvalde, Texas. With professional driver Brian Smith behind the wheel it hit an incredible top speed of 207.9 mph, making it the first gen-six Mustang->ke428 to exceed 200 mph.

Not bad for car that costs under $70,000, but perhaps the coolest thing about the HPE750 is its sleeper status. Aside from some subtle carbon-fiber aero additions, a vented hood, Hennessey wheels and a few new badges, it’s barely distinguishable from a stock Mustang GT. It also gets 15.1-inch Brembo front brakes to make sure it stop as good as it goes.

As it happens, Jay Leno was on hand to watch it all play out for an episode of Jay Leno’s Garage. Look for it later this year.

This is amazing footage. It just does the heart good, somehow, to see a Mustang go that fast.
