The curtain has dropped, the fat lady belted out her final note, yet an encore is called for. Although Dodge fulfilled its Last Call performance with several high-powered, unique versions of the Challenger and Charger, one car is returning for another round. The Dodge Challenger SRT Demon 170 receives the Hennessey treatment, taking its horsepower figures to insane heights, providing this amazing muscle car with one final moment in the spotlight.

John Hennessey's Demon 170 will be the first to receive the Demon 1700 Twin Turbo treatment.

A new Hennessey division takes on the Dodge Challenger SRT Demon 170 as its first project

Hennessey Performance Engineering (HPE) is well known for improving already impressive performance cars with upgraded equipment and high-tuned features. HPE created a new division called Hennessey Special Operations (HSO), which sounds much more like a secret part of the military than a car tuner.

This new division takes on the Demon 170 as its first project. This team will take the power of this high-powered Challenger to 1,700 horsepower, a figure never thought possible from the Hemi engine under the hood. Unfortunately, the 6.2-liter supercharged Hemi V8 won’t be part of the final product.

What engine does HSO drop into this Demon?

The HSO team pulls the stock engine, which produces 1,025 horsepower, and stores it. Maybe this engine could be used for a future project; who knows? The now-empty engine bay receives a specially built engine and transmission with two Precision 7576 turbocharges instead of a supercharger. This setup can achieve 1,700 horsepower while using E85 fuel.

How fast is the Hennessey Demon 1700 Twin Turbo?

With the old engine removed and a new, more powerful unit in its place, the Demon 170 receives a new name. This change tells us a little about the car named Demon 1700 Twin Turbo. Hennessey claims this car should be a full second faster in the quarter-mile than the stock Dodge Challenger SRT Demon 170, which finishes the run in 8.91 seconds at 151.17 mph. This new Hennessey Demon 1700 Twin Turbo should finish the sprint in 7.9 seconds at 175 mph, making it faster than the Rimac Nevera’s 8.25 seconds.

This speed and power doesn’t come cheap

Hennessey limits the new Demon 1700 Twin Turbo upgrade package to only 12 units. This first HSO project requires owners to first buy the Demon 170. Then they must toss in another $200,000 to receive the full package of Hennessey upgrades for this tuned-up car.

Hennessey puts its money where its mouth is

This new Hennessey division marks the third arm of the company. The HSO team will build 15-20 vehicles per year. This maintains a low volume of ultra-high-powered vehicles that provide more power and performance than their traditional counterparts.

The first of the 12 cars to receive the Demon 1700 Twin Turbo upgrade is John Hennessey’s personal Dodge Challenger SRT Demon 170. After that, the team will focus on building customer cars and starting new projects.

We can’t wait to see the next creation from the Hennessey Special Operations team.
