We’d go so far as to say that it’s even encroaching on supercar territory thanks to its quoted output figures of 580 horsepower at 6,000 rpm and 556 pound-feet of torque at 4,200 rpm.
However, the guys at Hennessey, which recently celebrated their company’s 20th anniversary with another special edition Camaro, aren’t holding back with Chevrolet’s latest, today announcing a range of performance upgrades that will see the car develop as much as 1,026 horsepower.
Yes, you read that correctly. Hennessey is offering a ‘HPE1000 Twin Turbo’ upgrade for the ZL1 that will deliver some 1,021 horsepower.
The upgrade is quite an intensive one, requiring the removal of the supercharged LSA engine and the installation of a 7.0-liter LSX unit with a custom twin-turbocharging kit. Unique features of the mega powerplant will include forged internals, high-flow cylinder heads, upgraded fuel injectors, an electronic boost controller and dual wastegates, an air-to-air intercooler, and a stainless steel exhaust system.
Note, interested customers will need to be able to drive a manual car as it’s only available with a heavy-duty dual friction clutch, and no, it won’t be legal in the state of California.
Fortunately, Hennessey will also be running some milder tunes on the new Camaro ZL1, starting with a base HPE600 package offering 610 horsepower, as well as HPE650, 700 and 800 packages with varying output figures being dialed up.
It looks like the horsepower wars are far from over…
