Ever since there have been Vipers, John Hennessey has been tuning them. Sometimes, it seems like his tuned cars are on the street before the production cars, if that's at all possible. And they were always incredibly bonkers.
And now, for the new SRT Viper, there are already two versions waiting in the wings: The Venom 700R and 1000 Twin Turbo. As you'd expect, they're packing a ton of powwwwwerrrrrrrrrrr.
