Hennessey Performance (HPE) has released another weapon for those determined to outgun all other vehicles on the road. This one is called the HPE700 Twin-Turbo Corvette Stingray - and predictably, it goes like stink.

While the stock, naturally aspirated 6.2-liter LT1 V8 under the hood of the Chevrolet is good for a healthy 455 horsepower and 450 pound-feet of torque, the good folks in Texas have moved the game on considerably by bolting on a pair of 62-mm turbochargers and cranking boost pressure up to 7 psi. With dual turbo wastegates, twin blow-off valves and intercooling to reduce the charge temperature, HPE has massaged the engine to produce 707 horsepower and 661 pound-feet of torque. Against a stopwatch, Hennessey says its HPE700 Twin-Turbo Corvette Stingray will hit the 60 mph benchmark in 2.9 seconds (factory stock is 3.8 seconds) and punch through the quarter mile in 10.5 seconds at 135.4 mph. Its top speed is estimated at more than 210 mph.

The turnkey price of an HPE700 Twin-Turbo Corvette Stingray is about $120,000 (including the donor Corvette with the 3LT and Z51 package), and buyers are able to choose whether they want a six-speed automatic or seven-speed manual gearbox and a host of other upgrades including HPE forged monobloc wheels and aerodynamics to provide additional stability at speed. The company expects to build just two-dozen examples, so you might not get to see one for yourself out on the streets if you can't make it to the car's Boca Raton Concours reveal. We've got the next-best thing, though - a burnout video - which you can watch by scrolling below.Continue reading Hennessey reveals HPE700 Twin-Turbo Corvette Stingray [w/video]
