Infamous due to strong encryption, the GM Global B E99 engine control module was cracked open by Trifecta Performance last year, thus opening the floodgates to high-output mods for the eighth-generation Corvette Stingray. The peeps at HP Tuners followed suit in 2023, which is why an increasing number of C8s are getting supercharger kits for a few more ponies.
Hennessey Performance Engineering, the Texas-based company that developed a 1,817-horsepower beast of a V8 with the same 104.8-millimeter cylinder bore as the LS7 small block, is much obliged to improve your Stingray to 708 horsepower. The so-called H700 package is priced at $34,950 (including a three-year warranty, installation, and testing).
Pictured in 70th Anniversary Edition flavor, the C8 in the video below is the perfect example of how your car will sound after getting the very same upgrades. Hennessey also listed it for sale, with pricing information available on request. It's not hard to guesstimate how much this fellow costs, though.
First and foremost, we're dealing with a 2023 model year 3LT Coupe (original MSRP listed by General Motors at $76,450) 70th Anniversary Edition ($5,995). Add $34,950 to the tally, and we're looking at $117,395 at the very least for this exact vehicle.
Showing 365 miles (587 kilometers) on the clock for a brief moment in the featured clip, the 70th Anniversary Edition is finished in a paint color dubbed White Pearl Metallic Tricoat. Referred to as G1W in the order guide, said color is joined by red brake calipers and anniversary badges in black and red. The black wheels with H caps are lightweight alloys measuring 19 and 20 inches, respectively.
Upholstered in a combination of black and white with red contrast stitching and a red 12 o'clock insert on the steering wheel, the H700-infused 'Vette rocks a 2.65-liter supercharging kit, a Roots-type blower that Eaton advertises under the TVS R2650 moniker.
It pushes the 6.2-liter V8 of the Stingray from the factory 465 pound-feet (630 Nm) or 470 pound-feet (637 Nm) with the optional sports exhaust system to a whopping 638 pound-feet (865 Nm) at 5,000 revolutions per minute. Let that sink in for a minute, then remember that General Motors quoted 650 pound-feet (881 Nm) for the C7-generation Z06.
The H700 package further includes high-flow induction, an air-to-water intercooler, and specific ECU calibration. This particular vehicle also sports an AWE exhaust suite, which is nearly $3,000 at press time. In other words, the car you're looking at is more than $120,000 with said exhaust upgrades.
If the Hennessey supercharged C8 Corvette Stingray doesn't pique your interest, fret not because a more powerful 'Vette is on the horizon. General Motors is currently putting the finishing touches on the all-new ZR1, which is due in 2024 for the 2025 model year.
Codenamed LT7, its engine is best described as the LT6 of the Z06 with a couple of turbos for good measure. Estimated peak horsepower? Given that the Z06 makes 670, maybe 800 ponies or more?
After a 1:43 scale model of a Ferrari 250 GTO sparked Mircea's interest for cars when he was a kid, an early internship at Top Gear sealed his career path. He's most interested in muscle cars and American trucks, but he takes a passing interest in quirky kei cars as well. Full profile
