Hennessey readies 1,200-hp, twin-turbo upgrade for the C8 Chevy Corvette


While it’s safe to assume Chevrolet is planning its own balls-to-the-wall successor to the C7 Corvette ZR1 based on the new mid-engine C8 Corvette, the car’s arrival is almost certain to be several years away.

For those who can’t wait for a big-power C8, Hennessey Performance Engineering will offer a solution. The performance car builder from Sealy, Texas, on Tuesday announced plans for a 1,200-horsepower version of the base Corvette Stingray.

The new ‘Vette reaches dealers in February and Hennessey said it will start modifying them later in 2020.

Starting with the LT2 6.2-liter V-8 that powers the Corvette Stingray, Hennessey will add a custom twin-turbocharging system and beefed-up internals to more than double the stock output of 495 hp. Specific mods mentioned by the company include forged aluminum pistons (10.0:1 compression ratio), forged steel connecting rods, and an reinforced version of the stock 8-speed dual-clutch transmission.

There will be milder powertrain upgrades, too, with Hennessey promising a stainless-steel exhaust system to improve the sound and lift power slightly. A supercharger upgrade with around 700 hp is also in the works.

Beyond the powertrain goodies, Hennessey will offer upgrades for the brakes, wheels, suspension, and styling, including body parts made from carbon fiber. Shown here are new items such as an extended front splitter, chunky side skirts, a roof-mounted scoop, and a huge rear wing.

“We are very excited about the new C8 Corvette and have big plans for it,” said John Hennessey, CEO and founder of Hennessey. “From mild to wild, we plan to offer a wide variety of track-tested parts and upgrades that come with a warranty.”

For the truly power hungry, Hennessey is also readying its own hypercar. To be called the Venom F5, the beast will come with a bespoke twin-turbo V-8 tested to over 1,800 hp and a promised top speed of more than 300 mph.

Hennessey, SEMA

The 1,200-hp, $200,000 Hennessey Resurrection Chevy Camaro ZL1 1LE worships at the church of speed


As the 2019 SEMA show kicks off in Las Vegas this week, John Hennessey has found religion.

The follow-up to The Exorcist—a 1,000-horsepower Chevrolet Camaro ZL1—The Resurrection has more power from a different engine, and is based on the current Camaro ZL1 1LE.

On E85, The Resurrection produces 1,200 hp at 6,800 rpm and 1,000 pound-feet of torque at 4,500 rpm. To get there, Hennessey’s team dropped the Camaro ZL1 1LE’s factory 650-horsepower supercharged LT4 6.2-liter V-8 and bolted in a 755-horsepower supercharged LT5 6.2-liter V-8 from the C7 Corvette ZR1. From there, The Resurrection breathes better with a high-flow air induction system and 112-mm CNC billet throttle body, while the factory 2.65-liter supercharger and cylinder heads are CNC ported and attached to an upgraded pulley. A larger intercooler double-times in The Resurrection, while the camshaft, pushrods, and valvetrain receive upgrades to handle more power.

The power is sent to the rear wheels through a 6-speed manual transmission with an upgraded Centerforce clutch and flywheel or a 10-speed automatic transmission with upgraded clutch packs and torque converter.

All of this translates to a 0-60 mph spring of less than 2.3 seconds on its way to a a 9.3-second quarter mile at 150 mph and top speed of more than 220 mph, according to Hennessey.

To feed the beast, the fuel system has been upgraded, engine management system has been recalibrated, and the engine received a tune.

It’s likely The Resurrection will be heard long before it’s seen thanks to its 1 7/8-inch long-tube stainless steel headers, stainless steel midpipes, and high-flow catalytic converters.

Each of The Resurrection Camaro ZL1 1LEs will come with a 1-year/12,000-mile warranty along with a serialized dash plaque.

Hennessey said it will only build 24 examples of The Resurrection and each will cost $200,000, which includes the cost of a Chevrolet Camaro ZL1 1LE.
