We already know everything there is to know about the Dodge Challenger SRT Hellcat. We've also seen this utterly powerful muscle car->ke507 perform in plenty of video footage, including a spectacular 10.8-second quarter-mile run, a lap around the Portland International Raceway, and an comprehensive review by automotive connoisseur Jay Leno->ke3731. What we haven't seen yet is the Hellcat put its 707 horsepower to good use on the dyno.

Well, that ends now, as the folks over at K&N Air Filters hosted Motor Trend and the Challenger Hellcat SRT they were testing for a dyno run. Making things more interesting aside from the that awesome supercharged, HEMI V-8 sound, the California-based manufacturer also released the output numbers the Hellcat cranked out on the dyno. So if you were wondering how much of the 707 ponies and 650 pound-feet reach the rear wheels, the answer is 635 horsepower and 591 pound-feet. Not bad at all. At the crank, the Hellcat churned 722 horses and 672 pound-feet, an impressive figure as well.

But that's not all. The video->ke278 becomes a bit more captivating toward the end, when the camera focuses on the car's instrument cluster. The footage shows the Hellcat accelerating through all the gears before redlining into its eighth cog at no less than 202 mph. That's two mph less than what the Charger SRT Hellcat can deliver, but enticing nonetheless. Hit the play button above for yet another awesome Hellcat video.
