Hennessey fires up the Dodge Demon 1700 Twin-Turbo V8 Hemi engine

Last year, Hennessey announced the Dodge Demon 1700 Twin-Turbo. This specially commissioned machine is being built by Hennessey Special Operations (HSO), which caters to customers looking for ultra-exclusive and ultra-high-horsepower vehicles.

The engineers at HSO have been working on the Demon 1700 Twin-Turbo for more than a year. Recently, the bespoke engine was put on a dyno, and here are the results:

The 7.2-liter twin-turbo V8 Hemi delivers a peak output of over 1700 hp, up from 1025 hp, which you get from the stock engine. To achieve such insane figures, Hennessey has replaced the factory supercharger with a pair of turbochargers.

This monster engine began life as a standard Hemi V8 in a brand-new Dodge Demon 170, which is now being transformed into the world’s most powerful Demon 170 ever created.
