Hennessey Upgrades Monster Corvette Z06

Testing Z06’s Power: Dyno Run for 1,000+ HP Project

Hennessey Performance have seized control of a Chevrolet Corvette Z06 and are striving to force as much potential out of the US sports vehicle. The modification business located in Texas has already initiated performance testing the current dominant ‘Vette, commencing with a dynamometer run to form the grounds.

Hennessey is quite familiar with tuning the C8, having now unleashed a 70th-anniversary Corvette enhanced with an amazing supercharged powertrain providing 758 horsepower. Although, this will be their very first venture in extending their expertise to the more powerful Z06 version.

The Chevrolet Corvette C8 Z06 flaunts an impressive 670 hp and 480 lb-ft from its 5.5-liter NA V8. Employing two overhead camshafts in conjunction with a flat-plane crankshaft as well as a dry sump lubrication system, this machine puts out considerable levels of power.

The foundation test run observed in the video indicates that the Z06 produces a little shy of 600 horsepower and 406 lb-ft at the tires, resembling earlier dyno outcomes from a third party. The findings similarly depict a slight torque augmentation in the lower cycles; something the tuning firm could rectify with the car’s concluding calibration.

One may be curious to know what sort of output could be drawn from the Corvette Z06. If we look at the company’s previous achievements, our guesses point to somewhere around a thousand horsepower. Although it is quite a challenge, Hennessey has accomplished this feat through their iconic H1000 upgrade on the Cadillac CT5-V Blackwing.

The tuners at Cadillac modified the super sedan by fitting it with a bigger supercharger, as well as revamping some of its internals to accommodate the amplified force. This alteration enabled the newly-tuned CT5-V Blackwing to accelerate from 0 to 60 mph in only 2.5 seconds and attain a maximum velocity higher than 200 mph.

The LT6 in the Z06 is an entirely different animal, primarily due to its highly-strung, naturally-aspirated powertrain. It may not be as easily enhanced with a supercharger as other Chevrolet models originally built for forced induction.

More specifics concerning the next installment of Hennessey’s Corvette Z06 upgrade will be made available shortly, and possibly even a drag race face-off against their other signature 1,000 horsepower models.
