It was possible, we thought. But now we know.

You already know that the Dodge Challenger SRT Demon does not have top speed. Dodge repeatedly stressed that the Demon was a drag-racer throughout the Demon’s teaser campaign as well as the months after its debut. The Demon’s maximum horsepower of 840 HP (626 kilowatts), is geared towards maximum acceleration. As we can see from the max performance run at Hennessey, the Demon accelerates to its factory-limited speed of 168 mph (or, as Hennessey observed, 164 mph) with great haste. This was without the Demon Crate’s special PCM. We now know that the car can do more.

Johnny Bohmer Proving Grounds had a 2018 Demon. had the racing fuel module, and they pointed it down 2.3 miles unobstructed runway. To see what happened. Jalopnik spoke to the team behind this speed run that took place in Florida on February 10. Apart from all the Demon Crate updates they also learned that the drag radials had been replaced with Pirelli P Zero rubber at each corner. The PCM upgrade that unlocks the 840 horses also removes the electronic speed limiter so you can run at full speed.

Johnny Bohmer set up his helmets and started rolling the cameras. He didn’t stop until the speedometer read 203 mph (326 km/h). Technically, the speed was recorded using Tag Heuer equipment according to the YouTube description. However, 203 mph is fast for any vehicle, not even a Dodge Challenger. There was still some speed left, so it is possible to improve on this figure, provided that there’s enough room. That number is still the Challenger Demon record.

Now, please confirm that the Demon will turn a quarter-mile in 9.6 seconds.
