Sealy, Texas – It was too much to ask that John Hennessey would leave the challenge posed by the upcoming 670kW Dodge Demon (“The fastest street-legal car in America”) unanswered and here, even before the reveal of the Demon at the New York motor show on 14 April, is his reply: the Exorcist.
It’s based on the 2017 Chevrolet Camaro ZL1, its supercharged 6.2-litre LT4 V8 radically upgraded with a bigger, higher-flowing blower running almost one bar of boost, high-flow induction and intercooler plumbing, ported factory cylinder heads, a hot cam and long-tube stainless-steel headers.
Maximum power is up from the standard 478kW and 883Nm to a claimed 735kW at 6400 revs and 1312Nm at 4400rpm – good enough, he says, for 0-100km/h in less than three seconds and a standing quarter mile (402 metres) in less than 10.
Yet he insists that this is not a thinly-veiled drag special but a genuine sports car that’ll perform equally well on the racetrack and can still be driven (legally!) on the street. And he’s happy to build you one with either the six-speed gearbox or GM’s 10-speed auto transmission – although he warns that the slushbox will need almost $10 000 worth of modifications to handle the extra power.
