Hennessey's Supercharged Shelby Mustang GT350 R Sounds Seriously Brutal in Chattanooga, TN

The team at Hennessey Performance just can't seem to stop hot-rodding America's newest muscle cars. They've tuned Hellcats and ZL1s to their absolute limits, and now, they've finally gotten their hands on a Ford Mustang Shelby GT350 R. Spoiler alert: it's already making over 800 horsepower. From the factory, the GT350 makes a respectable 526 horsepower and 429 lb.-ft. from its naturally aspirated 5.2-liter flat-plane crank V8. Clearly, that wasn't enough for the folks at Hennessey, because they went ahead and threw a supercharger on it. Hennessey put the forced-induction GT350 R on the dyno to see just how much power it could make, and managed a serious number: 787 horsepower to the wheels. Factoring
