Hennessey's 'The Exorcist' is a 1000bhp Chevrolet Camaro

Hennessey drops the church mic with 1000bhp Camaro 'The Exorcist' to be shown off in Houston on April 5

Texan tuning company Hennessey, famous for its crack at the ‘worlds fastest car’ title with the Venom supercar, has been busy developing a factory supported tuning kit for the new Chevrolet Camaro ZL1. Dubbed ‘The Exorcist’, the mad Camaro probably won't go down too well in America’s bible belt. Bu that's not really the target market for this testosterone-fuelled, pumped-up supercar.

Not a subtle car to begin with, the ZL1 already has a maximum output of 640bhp from a supercharged 6.2-litre LT4 V8 when it leaves the factory, so the numbers for this upgrade were never going to be small. Thanks in part to a larger, higher flowing supercharger and intercooler system with a max boost pressure of 14 psi, The Exorcist hits the magic 1000bhp mark. To stop the engine falling to pieces, Hennessey also add ported cylinder heads, an upgraded camshaft, stainless steel exhaust headers and a re-engineered intake system. 

Hennessey will offer The Exorcist with either a 6-speed manual or the new 10-speed automatic transmission co-developed with Ford. It is also offering an optional Drag Pack, uprating the driveshaft and adding 315 section radial drag tyres, leaving no doubt as to Hennessey’s target customer. With this package fitted, the Exorcist is claimed to do 60mph in less than three seconds and run the quarter in under 10 seconds.

Company founder John Hennessey insists that this is no one trick pony too, ensuring that the work Chevrolet has done in improving the standard Camaro ZL1’s on road dynamics has not been affected. Visually, The Exorcist is surprisingly restrained, with only a graphics pack letting the game away.

Available with an optional drag strip delivery – literally, the car is delivered to you at a drag strip – The Exorcist will be shown off at the Houston Motor Show on April 5, with only 100 units being produced every year. On top of the Camaro ZL1’s £49,000 purchase price, the Hennessey upgrade will cost a further £44,000 (or £51,000 for the auto) so heavenly salvation won’t come cheap.
