The Chevrolet Corvette C8 Stingray, a mid-engine marvel, has already captured the hearts of sports car enthusiasts across America. Known for its impressive performance straight from the factory, the C8 delivers a thrilling driving experience. However, for those craving even more power, Hennessey Performance, a renowned Texas-based tuner and hypercar manufacturer, has answered the call with their supercharged ‘H700’ upgrade package. This upgrade significantly elevates the Corvette C8 Horsepower, pushing it into a realm previously occupied by exotic supercars and even surpassing Chevrolet’s own high-performance C8 Z06 in terms of raw power.
In its stock configuration, the Corvette C8 Stingray hard top convertible (HTC) boasts a potent 6.2-liter LT2 V8 engine. This naturally aspirated powerplant produces a respectable 490 horsepower and 465 lb-ft of torque. While certainly exhilarating, Hennessey recognized the untapped potential within this American V8. To unlock this hidden power, Hennessey’s expert team meticulously engineered and installed a high-performance supercharger system. This system, designed to fit snugly within the C8’s engine bay, is complemented by an air induction system featuring an air-to-water intercooler. An enhanced cat-back exhaust system is also integrated to further optimize engine performance and deliver a more aggressive V8 soundtrack.
The result of these carefully selected and expertly installed upgrades is a staggering increase in Corvette C8 horsepower. The Hennessey ‘H700’ package elevates the engine’s output to an explosive 708 bhp and 638 lb-ft of torque. This represents a remarkable 44 percent increase in horsepower and a 37 percent increase in torque compared to the factory specifications. This power surge catapults the Hennessey supercharged C8 Stingray beyond the performance figures of even the highly acclaimed Chevrolet Corvette C8 Z06. While the Z06 is lauded for its track-focused capabilities and high-revving naturally aspirated 5.5-liter LT6 flat-plane crank V8, it produces a factory-rated 670 bhp and 460 lb-ft of torque – less horsepower and significantly less torque than the Hennessey H700.
John Hennessey, the founder and CEO of Hennessey Performance, aptly summarizes the impact of this upgrade: “Our supercharged C8 Convertible boosts America’s favorite sports car to extraordinary performance levels. We’ve unleashed the power that Chevrolet left on the table, boosting output by more than 200 bhp. Few cars, especially at this price, can deliver this level of power, acceleration, and engaging open-air driving experience alongside the Corvette’s distinctive V8 roar.”
The Hennessey Supercharged ‘H700’ Corvette C8 Stingray upgrade package is comprehensive, including not only the supercharger and intercooler but also a high-flow air induction system, upgraded fuel system components, cat-back exhaust, and expertly calibrated engine and transmission software. All necessary gaskets, fluids, and professional installation are also part of the package. For those seeking further personalization, optional upgrades such as an active-valve exhaust system, lightweight forged 19-inch alloy wheels, and the signature ‘Hennessey C8 Heritage Livery’ are available. The wheels can be finished in gloss black, matte gunmetal, or satin silver, and the livery comes in Blue, White, Black, Silver, or Red. Each Hennessey ‘H700’ Corvette is distinguished by ‘Hennessey’ and ‘H700’ badging and a unique serial numbered plaque, ensuring exclusivity.
The Hennessey ‘H700’ Corvette upgrade is compatible with all 2020-2024 Chevrolet C8 Corvette Stingray Coupes and HTC models. Backed by a 3-year / 36,000-mile limited warranty, the ‘H700’ package can be ordered through authorized Corvette retailers or directly from Hennessey Performance. For those looking to maximize their Corvette C8 horsepower and overall performance, the Hennessey ‘H700’ supercharger package presents an undeniably compelling option.
