Dragtimes went out and dynoed a stock 2008 Dodge Viper ACR with only 1,350 miles on the clock and found out some impressive results. They managed to get the Viper ACR to lay down 546 horsepower and 510lb-ft of torque which means 642 horspower and 600lb-ft of torque after you factor in a 15% driveline loss. That's quite a bit of power that Dodge forgot to put out in its press material and enough to justify the unofficial Nürburgring lap as legit.

So, is the Viper ACR really faster than the current American horsepower powerhouse, the 2009 Corvette ZR1? We'll have to get these two out to a track to really know for sure (Hello? Chrysler? GM? Are you listening?). Until that happens, take a look at the video above and the dynograph below to see who really is the king of the American power wars.

This is inverse to the two vehicles' Nurburgring laps, where the ACR managed a ZR1-defeating 7:22 lap record; the GT-R’s time is only 7:29.

So how does a 480 HP car weighing 3,814 Lbs accelerate faster than a car with 600 HP that weighs only 3,408 Lbs? We’re guessing the warranty-voiding launch control has something to do with it. [via Autoblog.nl]
