cant wait till track opens to try again ,Im hoping to be in the 11s without much changing but then Im after Eds times . he set a good bar with that 11.37 , seems like an impossible amount of tiime ill need to cut from a high 11 but will be coming off a brake , with an open dump, maybe a bigger I/C , slicks (26"), skinny fronts and less weight

times are from the last day of the season
thru the mufflers (hooker cat back), stock dutt I/C ,race weight 3670 (3/4 tank), MT et street radials (DR's) 255/50-16, motor is at 132K as it was shipped by GM back in november of 1987 with only valvesprings and a timing chain , heads and intake have never been touched or unbolted , as for the rest of whats bolted onto the motor, welll it aint stock except for the exhaust manifolds,crossover and of course turbo with stock bell (quick port to inlet and outlet )

timing was 27(max of my current chip)/23 (erics marshall's chip of course )
boost was 27-28 1-2 and then 25 in third (using bstc elc boost controll to drop it)
spaying straight meth (razors) through a single m15 nozzle (set at 12:00-1:00) turn on moved to 9# , initial adjusted just a bit
launch was off footbrake holding just under stall at 2750 (zero boost ) and car still flat on ground , then on second amber light flashing converter to 4000 (4.2 tps) and let go (3750 to 4000 seems to be the ticket)
locked converter at the line (switch in console), trans left in D not OD

Ds shows things arent quite right i have a miss (o2 drop) , could be a cam lobe ,still havent opened her up to take a look
egts are 15 mid to 1600, af is high 9s low 10s only seeing mid high tens near end of run
I added even more fuel toward the end of the day (+3%) and egt went up to 1600 but hurt spoolup a little and 2-3 shift wasnt as crisp , signs of just a little too much fuel/alky

dont ask what my scanmaster shows for O2 , you would pull out looking at those numbers but no Kr
i have DS files of almost every pass made this year
