The Dodge Challenger Demon 170 may be one of the most ridiculous road-legal muscle cars ever produced but that’s not enough for the folks over at Hennessey Performance. They have just revealed more details about their plans to create a 1,700 horsepower version of it following last night’s revelation.
This special model will be produced by the newly-formed Hennessey Special Operations (HSO) department which will produce just 15 to 20 vehicles per year for the firm’s most discerning customers. Production of Hennessey’s Demon 170 will be capped at just 12 units with prices for the upgrades to set customers back approximately $200,000, excluding the cost of the car itself.

While Hennessey usually upgrades OEM engines, that’s not what it will do with the Demon 1700 Twin-Turbo. Instead, it will replace the original 6.2-liter supercharged V8 with a new V8 built in-house with a pair of massive turbochargers.
This new engine will produce 1,700 hp, a huge increase from the 1,025 hp of the standard Demon 170 and enough to propel it down the quarter-mile in an estimated 7.9 seconds at 175 mph (281 km/h). That’s a whole second faster than the stock Demon 170 (8.91 seconds).
Hennessey has not yet confirmed the full list of modifications that it will make to the Dodge Demon 170 but has said that the original engines that it does remove will be shrink-wrapped and placed in a crate for safekeeping, meaning owners will be able to revert their vehicles back to stock should they choose.

“The transition to becoming a manufacturer with a factory producing lots of vehicles meant that we had to shift some of our resources away from the high horsepower vehicles that have kept the Hennessey name in the automotive headlines for the past 33 years,” John Hennessey said.
“We are happy to announce that we’ve created a new division within the company that allows us to build mega-powerful vehicles in small production runs. Taking my new Dodge Demon 170, removing the blower, adding a pair of turbos, and increasing power from 1,025 to 1,700 horsepower was exactly what we’ve been wanting to do.”
