Hennessey Performance Engineering has been making headlines ever since it first showed off its wild twin-turbocharged Dodge Viper builds. It’s most recent attention grabbing creation is the Hennessey Exorcist Camaro ZL1 – a Dodge Demon-inspired upgrade kit for the sixth-gen Camaro ZL1 that makes more than 1,000 hp at the crank.
HPE recently put one of their Hennessey Exorcist Camaro ZL1s on the dyno to test it for a 93 octane pump gas tune. The Demon can make a little more power on dedicated race gas, but this car is likely going to a customer who plans to use it mainly as a road car – so 93 octane it is.
The result of this dyno test was rather impressive, the Hennessey Exorcist Camaro making a stout 902 hp and 795 lb-ft of torque at the rear wheels. HPE claims the Exorcist is good for 1000 hp and 883 lb-ft torque at the crank, so their numbers seem accurate. The Texas-based tuning company also says the Exorcist Camaro can accelerate from 0-60 mph in around 3.0s, complete a quarter-mile in around 10s and reach a top speed of 217 mph.
HPE applies a range of mods to the Chevy to turn it into an Exorcist, but the biggest upgrade is a new 2.9-liter Whipple supercharger. Other mods include ported factory cylinder heads, a custom camshaft, longtube stainless steel headers, a high-flow induction system and custom engine calibration. The package costs $55,000, not including the cost of the Camaro ZL1 donor vehicle and includes a 2 year/24,000 mile warranty. It may be expensive, but beating Dodge Demon owners at the strip was never going to be cheap.
