Had a good time out at Crandall. Good to meet a few of y'all. Here are a few vids from today. First pass was on my street tune and it went 11.29@122. Second pass was my race tune and I was using the 2-step. For some reason at the 1-2 shift and fell on it's face and never really did recover. I thought maybe it loaded up too much on fuel or something. 3rd pass was off the footbrake on the race tune and it went 10.86@127.9. Glad to finally have some decent vids of my car and also some DATALOGS! I discovered from the logs a few interesting things. 1) My car doesn't make as much boost as I thought. It made 9 on the street tune and just under 12 on the race tune. 2) The car is definitely on the edge as far as the fuel system on the race tune. The last 500rpm of the pass the a/f went from 11.2 to about 12.0 and the fuel pressure actually dropped a couple of pounds. I don't guess I'll beat on it too much more until I get that addressed.

I haven't driven the car but once since my last trip to the track above. I think I found out why my boost levels were reading lower than I expected. I found a large vacuum cap that had dry rotted and was bleeding boost. It's the large (3/8" or so) line coming off of the drivers side on the bottom of the upper intake. I touched that cap I put on there and it fell off in my hand. I knew my boost readings were a little lower than I usually see, but it was my first log. I think once I get that fixed, and get my fuel system sorted out, I should see some 130's....
