le 1.5 track time

well we finally did some shake down passes on the car. We ran a couple of times , but the best time was a 12.20 @ 111mph w/ a 1.8 some 60' , not bad w/ that 60' that we got. Its also an auto, and the stall was only giving us about 2,000 rpm off the foot brake . Let me know what ya'll think. thanks josh.

Nice times, a better sixty foot and you may be looking at some high 11s.

Whats the complete list of mods and a complete breakdown of the pass? I trapped 111mph back when I was an auto with a slipping tranny that boucned off the limiter before it shifted and a baby 210/224 cam. It should have more in it.

12.2 looks good, but 111 with a 1.8 doesn't add up (at least to me)

Wonder if the track wasn't measuring trap speeds right. I would expect around a 118 with that 60' to do 12.2

Good either way though.

I ran 12.18 @ 116 w/ a 2.0, a 1.8 and 111 isnt that far off.

Hit the gas from idle. Stalling it up with the footbrake to 2000 rpms might not net you the best 60 foot. I'd drop to 20psi and go of idle on the 3rd yellow. What is your list of supporting mods?
