That's about what I trap in the 1/8, but I am usually a lower ET. I typically run a 7.8 - 7.9 in the 1/8 at 98mph, then do 11.6 - 11.8 in the 1/4 at 126mph.
I am guessing you would be faster than me from a roll, because if my ET is lower that means I'm probably getting better traction than you. And if I'm getting better traction, but we're trapping the same....then you are probably faster than me (accelerating at WOT for less time), even if I could get a better ET at the 1/4.
