The Demon is essentially a drag racer based on the Dodge Challenger platform. Dodge made this beast for those people who wanted more from the Challenger Hellcat. A Supercharged V-8 is the appropriate engine of choice for the Challenger. Due to high demand, Dodge built a limited number of Dodge Demon's that took the Hellcat equation and pushed it to a new dimension.

Although the Dodge Challenger SRT Demon has been out of production since 2018 and has since been replaced by the Challenger SRT Hellcat Super Stock, the Demon still remains a drag racing powerhouse. When it was first launched, Dodge claimed that the Demon would run the quarter-mile in 9.65 seconds on drag radial tires, making it the world's fastest car at the time.

Fast forward to today, and the Demon managed to get even faster in the hands of drag racers. He further broke his record by sprinting the quarter-mile in 8.8 seconds at 152 mph in January. 

Demonology set an even faster time in May, setting a new record thanks to a Nitrous-Oxide upgrade. The Demon demolished the quarter-mile in 8.78 seconds, with a trap speed of nearly 157 mph.} The engine has been also modified extensively, and its supercharged 6.2-liter V-8 is well beyond the factory specs.

The 2.7-liter Supercharger that forces air into the 6.2-liter V-8 by itself demands over a hundred horsepower run it. When the Demon runs on high-octane racing fuel, 0-60 mph takes just 2.3 seconds with the standard drag radials installed.

Quarter mile The Demon came with only a driver's seat as standard, and if you wanted to put those passenger seats back, they were available as a one-dollar add-on.

A couple of days ago, Demonology put out a video where the Dodge was fitted with a pair of 24-inch sized Corleone Forged wheels. This Demon now has big-lip rims, similar to those found on high-rises. He then took the car to an NHRA event for some severe rubber-burning and drag racing.

All passenger seats were removed on the Demon to save weight, and it weighed 215 pounds lighter than the Hellcat on which it was based. As we know, in drag racing, the sidewalls of the tires play a crucial role in getting off the line, so what exactly happens when you don't have those sidewalls and have street spec wheels instead?

Well, from the video, we can say that it's not all show and no go. The Demon does look pretty epic pulling up to the Christmas Tree. Despite the tires sliding, this heavily upgraded Demon pulls off an impressive burnout and appears to have set a reasonable time even though the 840 horsepower was deployed just to the rear wheels.

Demonology didn't give a quarter-mile time, however, in the video, Demonology says that there’s a learning curve with these new 24 inch rims and he’ll be getting new tires to eliminate the slipping.
