The Dodge Challenger SRT Demon’s standard drag radials can only handle a top speed of 168 mph, but the car can go faster. When you install the Powertrain Control Module (PCM) that comes in the optional Demon Crate, however, that speed limiter is removed. Swap in a set of tires like the Pirelli P Zeroes that come on the Challenger Hellcat Widebody and you can go very, very fast in a Demon.

Jalopnik reports that’s what happened at the Johnny Bohmer Proving Ground in Florida. A Demon owner took their car up to 203 mph on the proving ground’s 2.3-mile runway, as verified by Tag Heuer professional-grade timing equipment. The car was equipped with P Zero tires, and was using the Demon Crate PCM, which in addition to removing the speed limiter, allows for the use of 100-octane fuel, unlocking the V8’s full 840 hp.
A caveat, though. While 203 mph is quite fast, it’s worth noting that Dodge quotes a 199-mph top speed for the regular Challenger SRT Hellcat. So, 137 horsepower nets a gain of 4 mph. This 203-mph run is still impressive though, considering Dodge didn’t build the Demon for this sort of thing.
