With an extra 44 percent horsepower and 37 percent torque, Hennessey’s H700 package “erases” her Z06. Aftermarket specialists say it has far more power than the 670 hp and 460 lb-ft (624 Nm) that the Z06’s flat-crank 5.5-liter ‘LT6’ delivers. Additional power was achieved by installing a high-flow centrifugal supercharger, a custom intake system with an air-to-water intercooler and an optional cat-back exhaust.
Hennessey has developed a comprehensive upgrade package for the regular Chevrolet Corvette C8, significantly boosting the V8’s performance. His mid-mounted 6.2-liter engine, naturally aspirated, puts him out 490 horsepower and 465 lb-ft (630 Newton-meters) of torque, but those numbers increased significantly after he installed the supercharger. . His turbocharged LT2 puts out a whopping 708 hp and 638 lb-ft (865 Nm).
A tuner in need of horsepower, he charges $49,950 for his H700 kit tailored to the Corvette C8. He also has a set of lightweight wheels (19-inch front, 20-inch rear) in three different finishes: Satin Black, Brushed Aluminum and Graphite. These body graphics are available in red, silver, white, black, or blue.
John Hennessey has called the H700 “the most valuable high-performance supercar in the world” and offers good value for your hard-earned money. There are no changes to the standard 8-speed dual-clutch transmission, as the Tremec automatic transmission can handle the extra load.
If you want the extra power with no other modifications, a supercharger kit sells for under $34,950 on his. Hennessy adds the ‘H700’ emblem and individually numbered plates. Customers can take advantage of his 3 year/36,000 mile warranty and this kit is compatible with his 2020-2022 Corvette Coupe.
If you want his all-wheel-drive C8, the bowtie-badged company has one with his 2024 E-Ray Hybrid. As General Motors president Mark Reuss announced last year, an all-electric version based on GM’s Ultium platform is coming soon.
