The folks at Hennessey Performance Engineering have been very busy of late. The company has just announced that C6 upgrade packages are available for all 2008 – 2011 LS3 Corvette Models. They have been showing off a supercharged 2011 Corvette Grand Sport with an HFE600 upgrade. Packages to 650 and 700hp are also available. Ratings are based on 93 octane fuel and manual transmission.

Dyno testing shows the entry level package to produce 610 bhp @ 6,300 rpm, resulting in sterling performance numbers for 0-60 mph of 3.4 seconds and 1320 results of 11.4 @ 126 mph, according to the company.

The HPE600 Supercharged Upgrade includes the TVS2300 Supercharger System with a high flow air induction system, as well as fuel system upgrades, a 160 degree thermostat, all necessary gaskets, fluids and hardware.

HPE’s professional installation includes HPE engine management calibration, dyno tuning and road testing. Hennessey exterior badges, serialized dash and engine plaques and Hennessey premium floormats are part of the deal as well.

All parts and labor are covered by the company’s 3 Year / 36,000-mile Limited Warranty. Package pricing has not been announced at the moment.
