Video: Tuned Corvette hits 322km/h

The Chevrolet Corvette remains one of the most desirable supercars but imagine having a highway closed down for a speed run and hitting over 300km/h in a modified version?

Well Hennessey Performance tuners in Houston, Texas have been “making fast cars since 1991” and live by the rule of “There is no such thing as having too much horsepower.”

Watch the Stingray hit 322km/h VIDEO

Hennessey has put together a performance kit for the 2014 C7 Corvette Stingray. What’s more, you can even mail order your kit from anywhere in the world.

Founder and racer John Hennessey has put one of the tuner's products to test in a controlled run in Texas toll road reaching speeds of more than 300km/h.

The 6.2 V8 naturally aspirated Stingray was fitted with a HPE600 upgrade -Z51 upgrade and MR suspension - pushing out 440kW at 6500rpm (that's 600 horsepower hence the HPE600 moniker) and an extra 75kW from the Nitrous Express kit. The engine is mated to a seven speed manual.

The standard model delivers 340kW and its top speed is rated at 288km/h.

The run took place on the Grand Parkway which on the west side of Houston, Texas in December 2013. Hennessey clocked a verified time of 322.8km/h (200.6mp/h), making it the first Stingray to break the 300km/h barrier.
