Well you're right, there is no skill involved with racing from 80mph.
You can't really quantify how quick a car is 80-115. I've only been to the track once, and ran 7.98 at 88 in the 1/8 on my fourth pass ever. On that day it was the quickest of nine n/a 5.0s at the track and nearly all of them had tunes and exhaust. It was also quicker than the two supercharged 3-valve GTs there. I think I can back up my claim. What have you run?
