The car has ran 11.34@120mph in evening air(cooler)spinning off the line.Traction problems solved,wasn,t heating them up enough.Duh.
As you may know, when you spin your MPH does pick up, so thats where the 120 came from, you abviously spun because the car picked up once the sun went down, i feel you can do it the way the car is now in "good" air with plenty of bite, because you should pick up ET & MPH even though you may only pick up .3 -.4 on the 60ft. in cool air, i normally lost a solid .2 & 2 from fall too summer with no jet/timing changes "dead" hooking, 60ft. would be 1.60 -1.62 in the heat, 1.57 - 1.58 in good air, low-mid 10.9s fall, high 11.0s in summer, as bad as low 11.teens, but my MPH was 122-123 in good air, 120-121 in the heat & crappy suspention all the time :angry7:, i should have been in the 10.7s easy, If you do decide to try out the 4.30s, run the 28" slick, this may give you the MPH & put you in the 10s.
I don't know what your trapping with the 26s & 3.91s, i'm sure its alot, when i ran a 26" slicks & 4.11s (not much diff. from 3.91s), i ran out of steam "bad" around the 1000 ft., get this lol, car ran 11.98 @ 98 :-D, ALL i did was install some 28" slicks & my 1st. pass the car ran 11.21 @ 119 8), all from just a tire change, & beleive it or not, my 60fts. "dropped" with the taller tire even though the car was hooking decent with the 26s, go figure :munky2:
