The Hennessey-possessed Demon 170 will get the custom-built engine with a pair of precision 7576 turbos instead of the supercharged HEMI installed by Dodge’s Special Racing Technology gang.

With over 1,000 horsepower, the Dodge Challenger Demon 170 is already a handful. So, naturally, you'd want to chop the roof off and make it even tougher to manhadle, right?

The Demon was born out of Dodge’s idea for a new production sports car. The company wanted a front-engined, rear-wheel-drive model that would occupy a place in the lineup just below the Viper.

Dodge’s 1,025 hp Challenger Demon 170 can fire down the quarter-mile in a remarkable 8.91 seconds, putting both supercars and hypercars to shame. However, Hennessey is making it even faster.
