Generally speaking, the Dodge Challenger SRT Demon is a car that doesn't need any extra help to go really fast. With up to 840 horsepower on tap and a suspension designed for brutal launches at the drag strip, it's capable of running quarter-mile times under 10 seconds straight from the factory. But that's the thing about speed – once you reach a certain level, you always want to go a bit faster.
The Challenger SRT Demon featured in this video from MotorTube is a perfect example. The clip already captures our attention simply by featuring an SRT Demon, as these are rare with only 3,300 built during its short production run. Then we get to the real eye-opener for this muscle machine, and it's not the bright green finish. Instead of going for a pulley and tune to make more power from the supercharged Hellcat V8 engine, this Demon ditches the blower in favor of two turbochargers.
