Turbocharging a 2014 Chevrolet Camaro ZL1 might sound like an insane thing to do — some would call it blasphemous — but the folks over at Hennessey have no issues in replacing the muscle car ’s supercharged V-8 with a larger-displacement eight-pot and a pair of turbos.
The swap comes by way of the tuner’s HPE1000 package, which can also be fitted to the 2014 Corvette Stingray or the SRT Viper . As the name suggests, the upgrade plants no less than 1,000 horsepower under the hood, with all of them fully unleashed at 6,400 rpm.
For that spectacular oomph to become available, Hennessey ditches the ZL1’s supercharged 6.2-liter V-8 in favor of a 7.0-liter LS V-8 and a pair of ball-bearing turbochargers and other key updates that include forged-aluminum pistons, a custom camshaft, high-flow cylinder heads and an upgraded fuel system.
Naturally, the vehicle benefits from the company’s engine management calibration, and goes through a series of dyno and road tests before being delivered to its lucky owner. As seen in the video above, trials also include a few quarter-mile passes, obviously conducted for Hennessey to ensure the ZL1 reaches the parameters the HPE1000 package claims to offer.
We’re not going to spoil the result, but this twin-turbo Camaro ZL1 returned some spectacular figures. Needless to say, Hennessey is about to make yet another customer happy.
