Early in April Hennessey Performance rolled out a new tuner car that was meant to directly attack the Dodge Demon street/strip car. The Exorcist is a Chevy Camaro ZL1 that has been massaged to make a lot more power than Chevy ever intended from the factory. The rating Hennessey gave is 1000hp.
The Hennessey folks have taken The Exorcist to their in-house dyno to prove exactly how much power the car makes. The result is a 959 rear wheel horsepower rating for The Exorcist proving the 1000hp claim for the car.
Hennessey will build you your very own Exorcist on your existing car for $55,000 on top of the price of the car. You can buy the vehicle turn key as well. If your ZL1 has an automatic transmission, add another $9950 to the price to cover upgrades to the transmission.
