Here is a mean Viper powered 2011 Dodge Challenger testing at Byron Raceway couple of years ago. This factory drag pak beast rocks a 512 cubic inch V10 Viper engine plus few shots of Nitrous and scores pretty good at the 1/4 mile. Not sure exactly how many horses is this Mopar capable of, but it runs 8.54 seconds @ 153 mph which is not bad at all.

Check out the video our friend James Hrovat filmed at the strip to see this bad boy.
