Hennessey Performance has announced their range of upgrades for the Chevrolet Camaro ZL1. Hennessey’s Camaro ZL1 is available in four versions: HPE650, developing 658 bhp at 6,200 rpm, HPE700 with 707 bhp at 6,300 rpm, and HPE800 with 800 bhp at 6,200 rpm.
The top of the range Hennessey Camaro ZL1 is the HPE1000, which outputs no less than 1,021 bhp at 6,400 rpm. Take that Veyron! The HPE1000 is powered by a 427 cid LSX engine, featuring forged crank, pistons and rods, as well as other modifications. The Hennessey Chevrolet Camaro ZL1 HPE1000 also features an upgraded fuel system, twin ball bearing turbochargers, dual wastegates and an electronic boost controller. An air-to-air intercooler and a high-flow K&N air filter are also required. The standard transmission of the Chevrolet Camaro ZL1 can not take the 1,000 hp of the HPE1000, so Hennessey has to replace the original clutch with a Centerforce Dual Friction one.
Apart from the incredible power increase, Hennessey’s HPE1000 package for the ZL1 also includes various badges and serial-numbered plaques on the dashboard and engine. The HPE1000 kit for the Chevy Camaro ZL1 comes with professional installation, engine calibration, and a 1 Year / 12,000 Mile Limited Warranty.
Hennessey did not disclose the price of their HPE1000 upgrade for the Chevrolet Camaro ZL1.
