Went over to Island today for sunday T&T. Got there at about 12:30, sat in tech line till 1:15, then in line till after 2:20 for my first run. The place was PACKED with cars.
Run 1:
1.640 60'
4.939 330'
7.609 @ 93.97 1/8
9.870 1000'
11.800 @ 117.14 1/4
~23psi steady boost, no knock, mid 11's a/f, 13 to 15* timing.
Launch rpm was 6200, but I didn't get on the 2step until the last light so I left with pretty much no boost/free rev. it still came out smooth and fairly quick. I lifted the 1-2 shift and made it way early at 6800rpm /ubbthreads/images/graemlins/banghead.gif
Youtube video of first run
My wife & kids left after the first run, my boys are only 4 and 2 years old, the big loud racecars & smoke were a little too much for them. Island also seems to have a nasty yellow jacket bee problem in the stands. So I only have video of my first run. They waited over 2 hours to see me make one pass, which musta sucked.
Second run:
1.656 60'
4.837 330'
7.418 @ 96.82 1/8
9.626 1000'
11.509 @ 120.21
Boost hit 28psi and start a steady decline to 24psi by 7500rpm. /ubbthreads/images/graemlins/dunno.gif
raised timing 1*, but saw some knock (less than 8counts) in 3rd and 4th.
NLTS all gear shifts, but I let out in first gear right after the launch. I let the clutch slip just a bit too much and it kept slipping after the pedal came up, so I blipped the throttle in first to let it grab.
Third run:
1.621 60'
4.776 330'
7.344 @ 97.40
9.541 1000'
11.410 @ 120.96
same tune/boost setting, still dropping from 28 to 24psi. /ubbthreads/images/graemlins/bawling.gif
I did the same damn thing in first gear again...letting clutch out too slow, it doesn't feel like it grabs 100% and I lift throttle out of instinct for just a bit. Either way, a decent pass I think, but the 60' could be better when I stop being a pansy and just drop the clutch faster. /ubbthreads/images/graemlins/rofl.gif
Saw knock counts of 13-14 in 4th gear, which pulled the timing down to 9*.
air temps were about 93* on the line and hit 121*F in 4th gear/ubbthreads/images/graemlins/noes.gif
A/F was still mid to high 11's, but I think I should try a little richer and less timing in the map so it stays off knock all together (or a little squirt of meth).
So I'm pretty happy with an 11.4 @ 121 on pumpgas, park the car and load up my tools, reinstall the headlight. Go to leave and the car wont start. after some investigating: no fuel pressure on gauge.
Check the pump, I have power at the plug. Pull out the sending unit and jumper the pump to the battery: it only turns on after getting whacked with a ratchet and was intermittent.
So supra pump died and left me stranded in the pits waiting for a tow truck. /ubbthreads/images/graemlins/rofl.gif
(Iphone pics are not so wonderful quality, but that's all I had with me)
