Based on the new 2017 Chevrolet Camaro ZL1, the Hennessey has increased the Chevy’s LT4 V8 engine’s power from stock 640 hp and 640lb ft of torque to massive 1000 hp at 6,400 rpm and 966 lb-ft of torque at 4,400 rpm. To get this extra ponies, the tuner has made a series of modifications, including a larger, higher flowing supercharger and intercooler system producing 14 psi of boost pressure. The factory cylinder heads have also been ported and camshaft has been upgraded. There’s also high-flow air induction system, long-tube stainless steel headers and custom engine management calibration. All of that combined with drag radial tires will enable the Exorcist to run from 0-60 mph in under 3 seconds and the 1/4 mile in less than 10 seconds.6
The base cost for the Exorcist upgrade plus graphics is $55,000. However, if you don’t have a ZL1, you can buy a base Exorcist for $119,000. Hennessey is also offering and the two optional packages.
