Honestly can't tell you times. I don't remember the date, but should be on the viper truck site. The vipers were running mid to low 12's all day. I was running consistently mid 12.5's back to back. The copper one was hitting the 11's after a while. Yep, it was pretty much driver advantage disadvantage however you want to look at it. I know I could put one of the vipers deep into the 11's. I don't mark my slips, I guess that would be a good idea. I had no clue this video was around. I believe the event was in Jan or Feb of this year. This bit is info is food for thought. I had raced them before pulley and dr's in december and no matter how far out I was they would catch me. Same with the vid against the cls63. Once I was pullied the midrange improved and it was all about reaction time on heads up.
