From the factory, the Dodge Challenger SRT Demon is speed-limited to 168 mph. That's because the drag radial tires equipped from the factory aren't designed to go any faster. But, when you remove the speed limiter using the car's second power control module from the Demon Crate and swap on some more high-speed capable tires, it can go faster. Much faster. 

This was first tested in February 2018, when a Demon owner took their car all the way to 203 mph at a Johnny Bohmer Proving Grounds event in Florida. Recently, a different Demon attempted another top speed, and it went even faster, hitting a top speed of 211.227 mph:

This record was also achieved on the 2.7-mile-long Johnny Bohmer Proving Grounds runway. Despite its big blocky fascia, massive air scoop, and heavy curb weight, the Demon pulls hard all the way from start to finish. That supercharged V-8 has something to do with it. In addition to removing the speed limiter, the power control module from the Demon crate allows the this 6.2-liter motor to run on 100-octane race gas, bringing output from 808 horsepower to 840. It's only towards the end of the run that Demon stops accelerating hard, but if the car were given enough room, we bet it could squeeze out another mph or two.

After seeing runs like this, it's clear the Demon is more than just a quarter-mile hero.
