I have some miserable videos of one racing this past weekend.
I have nothing but respect for the guys that mod Vipers, though. I saw a 1300hp twin-turbo setup in one once. It might have been more, but that was as high as the dyno could measure. Impressive!
Not many exist, I was just stating the fact that he didn't keep up with a regular Viper. He stayed even with a Viper that was trapping 133mph at the time. Which now I believe it's made a run of mid 9's @ 150mph.
