Before Dodge even showed the wild Challenger SRT Demon to the world, Texas tuner John Hennessey promised he had something that would beat it. This is it: a 1000-horsepower Camaro ZL1 dubbed The Exorcist, which promises sub-10 second quarter mile times.
On a recent dyno test, Hennessey measured the Exorcist as making 959 horsepower to the rear wheels. That's a lot of power—plenty more than the Dodge Demon, which needs 100--octane race gas to achieve its max power output of 840 horsepower at the crank.
But horsepower isn't the only fighting point between the Demon and the Exorcist. The Demon brings giant drag radials, adaptive dampers designed to maximize weight transfer to the rear, and a trans brake, all in the name of launching hard off the line. That's how the Dodge, with "only" 840 horses, can run a 9.54-second quarter-mile. Will Hennessey's Demon-buster be able to generate similar grip to hook up and rocket down the drag strip? We'll just have to wait and see.
Of course, the Demon comes with a full warranty from Dodge, whereas the Exorcist comes with just a two-year/24,000-mile limited warranty from Hennessey. In any case, we'll need to see a real drag race before we can declare a definitive winner here.
