The new Hennessey Dodge Challenger SRT Demon

The HPE1000 Demon Upgrade

I love the standard SRT Demon but Hennessey have taken it to another level.
The standard car produces 840bhp and a 1/4 mile of 9.65 seconds at 140mph, which for most people would be plenty.
Like all Hennessey's cars, this is not enough, and they add their own special touch.
This time, producing a SRT Demon that can do the 1/4 mile in 9.14 seconds at 152mph and reduce the 0-60 time by 0.4 seconds to 1.9 seconds.

The upgrade includes replacing the standard 2.7l supercharger with a massive 4.5l one, which increases engine hp to 1035 and 880 at the rear wheel. Torque is also up at 806 Ib-ft.
The SRT Demon production is being limited to 3000, and the Hennessey upgrade to just 50 units.
​All this includes new headers and induction and comes with a 1 year/12,000 mile warranty - which isn't bad for a drag car.
