The hunk of sweet Mopar goodness known as the 2013 SRT Viper GTS is all set to hit dealerships and the streets at the control of civilians. Before this can happen, all of us experts had to run it through the ringer and Edmunds sure got a good long look at the new snake. During this testing process, Edmunds somehow managed to get SRT’s permission to put the SRT Viper on the dyno – something that a surprising number of automakers would never allow out of fear of huge horsepower loss through the drivetrain.

As we all now, the Viper GTS has been dubbed the “most powerful Viper ever,” thanks to its 8.4-liter V-10 engine that pumps out 640 horsepower and 600 pound-feet of torque. While stated output is all well and good, what really matters is how much of that power actually makes it to those monstrous rear tires.

With the Viper on the dyno, Edmunds lets us know what to expect from the resurrected serpent. Wanna know the results? You’ll have to check out the video to find out…
