Hennessey will turn your Camaro ZL1 convertible into an Exorcist, too

Just before Dodge unveiled its 840-horsepower Challenger SRT Demon, American tuner Hennessey Performance preemptively revealed a competitor called the Exorcist. The Exorcist is an upgraded Chevrolet Camaro ZL1 making a whopping 1,000 horsepower thanks to a bigger supercharger, upgraded camshaft and intercooler, ported head, new headers, and a tuned ECU.
