In February of last year, Hennessey Performance Engineering promised us they would produce a twin-turbocharged 2014 Corvette Stingray with 1,000 horsepower. HPE hasn’t quite filled that tall order yet, but they are well on their way with the completion of the HPE700 twin-turbo kit for the C7 Corvette.
Hennessey’s HPE700 Corvette is producing 608 horsepower and 568 lb-ft of torque at the rear wheels, with an estimated 708 horsepower at the crank. That might not seem like a huge improvement over the stock C7’s 450 horsepower output, but bear in mind that the HPE700 has completely stock internals. It’s also running relatively low boost, only 7 psi, due to the LT1’s high compression ratio.
HPE says it will only produce 24 twin-turbo C7 Corvettes for 2014, so prospective buyers should act now. Unfortunately, California residents will have to look elsewhere, as the HPE700 is not yet CARB certified.

So if I live in California can I register this car in another state and bring it to California?
Cost the one thing I hate about these performance articles is they don’t include what a total package price will cost!
Does this setup come with a warranty? Does this void the new cars warranty?
This voids the factory warranty. HPE offers a 1 year, 12,000 mile warranty with the package. I cant speak for all but most companies require you to give them a call for pricing.
So why would someone do this right out of the box with a new car?
Is there a mile restriction to do this mod on a car? In other words will they not warrant a car with x number of miles on it? Because a old engine won’t handle the new power!
