Twinvipers have you won any of the viper drag racing series, i think not however Roof has won three or four. It's easy to lay down a time under test and tune because there is no pressure on you like cutting a good light etc. Your car is fast however it has yet to beat Roofs ET or MPH. If you race long enough you will break its all part of the game as they say if you don't break you are not pushing the envelop. Good luck to both of you but twinviper give the man his dues he has earned it whether we like him or not.
