This was already a couple weeks ago, but things have been busy lately and it took me a while to get the video pieced together. We made it out for the last time of the season 10-18-09 and, unfortunately, left with a big window in the block.
Pass 1:
Off the trailer at ~44psi it rattled the tires, I pedaled it and I thought it was a bad pass so I lifted about 100-150ft early - 8.39 at 158mph on a 1.29x 60'
Pass 2:
Try to add more boost but it doesn't make any more. I need a stiffer wastegate spring. 8.37 at 165mph on a 1.290 60' - new best ET.
Pass 3:
Minor tune change that didn't make any more power. Best ET of the year:
1.294 60'
3.561 330'
5.408 at 133.96 1/8mi
6.997 at 153.06 1000'
8.358 at 164.90 1/4mi
Pass 4:
Try to make an intake cam timing change. Find out the Haltech software won't target negative value in the table. Shook the tires at the top of 1st and shifted while pedaling it so it bogged a little. 8.48 at 164mph on a 1.31 60'
Pass 5:
Lined up with Scott's RWD car. Made a cam timing change. A rod let go at 8600rpm in third gear (~150mph). The catch pan caught everything, so that was good, but our day and season are over.
We're done for the year. I expect it will make more power at more boost, but I need to change the wastegate spring to run more. I thought I had at least 5psi more I could go before it would blow the wastegate open with the 12psi spring but I guess I was wrong on that. It is just now hitting 1:1 backpressure at 43-44psi.
