Hennessey Performance Engineering (HPE) revealed its aftermarket solution to the factory powerhouse of a muscle car, introducing the Exorcist Chevrolet Camaro ZL1. HPE added a larger supercharger to the Camaro ZL1’s 6.2-liter LT4 supercharged V8 engine and dials the boost up to 14 psi. The Exorcist Camaro is also assisted by ported factory cylinder heads, long-tube stainless steel headers, a camshaft upgrade, a high-flow air induction system, and a customer engine management calibration from HPE. HPE plans to build 100 Exorcist Camaros, but they haven’t revealed how many will be coupes and how many will be drop tops.
