2013 SRT Viper GTS dyno'd by Edmunds

First-time dynamometer runs for any production car are interesting business, at least for those with "car nerd" in their resumes. And the virgin public dyno testing of a new supercar like the SRT Viper GTS, well, that's just a bit o' heaven right there. So, when we heard that the number crunchers at Edmunds had gotten the new Viper into the test facility, we were hooked right away.

We won't spoil the video for you by blowing the ending right here, but suffice it to say that the SRT 8.4-litre V10, rated at 640 horsepower and 600 pound-feet of torque at the crank, is still pretty super by the time the power makes its way to those wide rear tires.
