E85 bolt on 600 rwhp GTR's can run 9's. I don't think I've ever seen a stock Viper come anywhere close to that. I call major BS!!Having a hard time believing that a 600 awhp GTR loses to 470hp viper. Anyone in the tri state area have a 08+ viper ? Bc my GTR just happens to make 600hp and i DESTROY bolted Z06s.
