OK this will be my data post.

60', 1/8, MPH, 1/4, MPH

2.188 / 8.067 / 102.31mph / 11.894 / 130.20mph - VIDEO HERE
first pass, i suck at everything, running 11psi. I check tire pressure and drop it a little.

1.958 / 7.677 / 103.43mph / 11.446 / 133.37mph
do everything a tad better, might have tried adding boost (going about it slowly because settings on dyno and street are different, and i dont want to go too high)

1.913 / 7.574 / 103.80mph / 11.336 / 133.90mph
same thing. think i dropped tire pressure a couple more psi

1.858 / 10.876 / 54.24mph / 18.448 / 63.06mph
i turned up the boost and made about 11.5. I also got the tires heated up a little better and it gripped more, causing me to bog. But still got better 60' that previous. Unfortunately when the boost came on the extra power was enough to light up the rear tires. I got locked out of 2nd and drove nice the rest of the way. After this pass I went into the boost controller and set the boost by speed to keep the boost level below 60mph to about 10.5psi and leave it there the rest of the night.

2.049 / 7.607 / 103.65mph / 11.308 / 133.41mph - VIDEO HERE
nothing to see here really. decent pass with crappy launch. Raced a vette. This vette and I had indentical 60' and 1/8 numbers, but his RT was .5 quicker which is why he started out ahead. For some reason he let partly off just before the 1000' otherwise i probably wouldnt have passed him... his numbers on other runs were very close to mine. Notice that I ran out of gear just before the end and didnt have time to shift into 5th. So the 28s with stock final drive was not able to keep me from topping out 4th before the end. Probably cost me a tenth.

2.045 / 7.572 / 104.61mph / 11.323 / 123.59mph
im picking up mph as i slowly bring up the boost... between my crappy 60' and a little more boost (i think i hit 11.7psi this run) i gain too much mph and i run out of 4th well before the end and attempt to get into 5th but miss and coast.

1.896 / 7.502 / 102.33mph / 11.226 / 133.78mph - VIDEO HERE
A mediocre launch, good enough to bring the ET down a little. I take too long getting into second. I see that my time hardly dropped despite the run feeling cleaner. I check the peek hold and my boost was lower on this pass. I turn up the boost a couple notches trying to get the damn thing to run my 12psi.

1.891 / 8.126 / 73.94mph / 14.828 63.04mph
This is where my clutch problem becomes obvious. The engine is just climbing to redline but the car isnt coming with starting in 2nd gear.

1.719 / 7.327 / 100.45mph / 12.708 / 66.31mph - VIDEO HERE
And this is the run that would have been it... a low 1.7 60'... my 1/8 mile time, despite slipping and staying in it, is 2 tenths faster than all my other 1/8 miles... and 2 tenths was what i needed. The better launch brought my MPH down so I should have been OK to finish in 4th. GRRRR the car just stops pulling towards the top of 3rd so i let out and touch the brakes... and yup drove through a 12.7 LOL.

I let the car cool down for about a hour and try again. No luck. I make 2 passes and its worthless. I lost one of the timeslips but one of them was:

1.847 / 7.598 / 93.43mph / 12.649 / 83.21

And the car has trouble driving up the trailer with the clutch slipping so bad.
