Need More Power? Hennessey has you covered!

Not satisfied with the 455 horsepower on the standard 2014 Corvette Stingray?

Then you might want to talk to the folks at Hennessey Performance, who are offering two performance upgrades for the new C7.

The Hennessey Performance C7 Corvette Stingray HPE500, appropriately enough, raises the horsepower to 500, thanks to a new computer calibration and an upgraded exhaust system with steel long-tube headers, high-flow cats, and midpipes. Hennessey is making only 500 of these units, with a price of $4,995 installed.

You can up that horsepower figure to 600 by opting for the HPE600 that requires 93-octane premium gas and uses a special hydraulic roller camshaft, along with porting and polishing of the factory cylinder heads, to add another 140-hp to the stock motor. Cost of this package is $10,950 installed.

It’s not all about the engine, though. The HPE cars look tougher, too, with Hennessey H10 forged monoblock wheels that cut 19 pounds off the unsprung weight, a special Carbon Aero body kit with a deep front splitter, a notched rear wing, and carbon-fiber door sills.

You also get a 3-year/36,000-mile powertrain warranty from Hennessey Performance.

And, if that’s still not enough performance for you, word is that Hennessey is working on supercharger and twin-turbo systems that crank out 1,000-hp.
