Hennessey is notorious for taking automakers’ engines and making them insanely powerful. The Texas tuner’s latest project takes the Dodge Challenger SRT Demon 170, which is already insanely powerful with 1,025 horsepower under the hood, and cranks it up to 1,700 hp. Hennessey’s Demon 1700 Twin-Turbo will have, as the name suggests, a twin-turbo system instead of a supercharger.
