The all-new 2014 Chevrolet Corvette C7 Stingray hasn't even arrived in showrooms, but that minor speed bump hasn't slowed Hennessey Performance (HPE) from introducing a full suite of packaged (and à la carte) upgrades to the highly anticipated American sports car that will undoubtedly trump even the factory's future high-performance Z06 and ZR1 models.

In base form, the C7's new 6.2-liter V8 will be rated at 455 horsepower. While that's a strong start, Hennessey's first two packages bolt on a TVS2300 supercharger system and other miscellaneous upgrades to find upwards of 150 additional horses (both come with a 3 Year/36,000-mile warranty). The more aggressive packages start with an HPE custom balanced and forged engine that is accompanied by two ball-bearing turbochargers, forged pistons and plenty of other go-fast hardware to deliver up to 1,000 horsepower (both come with a 1 Year/12,000-mile warranty).

The company has announced four different upgrade programs (prices include professional installation):

  • HPE600 Supercharged ($12,495) 600 hp @ 6,300 rpm
  • HPE700 Supercharged ($18,450) 700 hp @ 6,300 rpm
  • HPE800 Twin-Turbo ($54,950) 800 hp @ 6,300 rpm
  • HPE1000 Twin-Turbo ($67,950) 1,100 hp @ 6,300 rpm
John Hennessey told Autoblog that his company has been planning the C7 upgrades "for over a year" and that his team is "confident that we will be able to adapt the same types of upgrades that we have been doing for the C6 models over the past several years." While he was unable to offer any performance estimates, Hennessey reminded us that his HPE700 upgrade on the C6 Grand Sport ran 0-60 in 3.3 sec. and 10.7 sec. @ 128 mph. "I would expect similar performance on the C7 or possibly a bit quicker," he said. "We prefer to be cautious on performance estimates and promises until we know for a fact what the numbers are." Hennessey Performance plans to have the first cars in customer's hands by the end of the year.
