Why "shake down round 2"? ... because after the first two passes, we just changed the rear tires.
Went from 28" Hoosier slicks to some warn out "shop loaner" 26" BFGs
First pass - BFGs at 10psi ... because I was too lazy to put more air in them.

Now, both passes the previous weekend (different track), the car hazed the entire track and no one gave me a second look. Yes, this thing is pushing oil out the breather and creating a nice cloud behind it.
This time, we had removed the breather and rigged a "coke bottle" catch can. A track official stopped me on the return lane to make sure nothing was broken or seriously leaking. The hose had blown out of the coke bottle. They did a quick review of the track condition and racing resumed.
Second pass ... or lack there of.
I did my burnout and was staging the car when Jason jumped out in front of the car and waved me off because the car was "pouring oil". -- Took it back to the pits and found out the oil dipstick tube had been blown out of the block. Fixed that and strapped the tube down to everything I could find. (There's no EGR on this thing so there's no bolt for it anymore. )
Okay, actual second pass. -- Had some time while I was fixing the dipstick -- BFGs at 15psi.

Again, the car hazed the track. I was happy with the pass so I just went back to the pits... Where I was informed that the car hadn't just hazed this time. Opened the hood to find out the catch can was GONE.
What we learned:
1) This thing has some major crank case pressure issues right now (at 10psi). I'm looking into (a) a better catch can setup, (b) a vaccum pump setup to solve the problem.
2) I've maxed out the factory MAF - Gotta get that replaced/rigged up, figured out.
3) This stock 2000-2400 stall sucks... stock 3.23s suck.
/end overall good day
Additional ... - New best!
*update
We also found out that the low/reverse clutches in the trans were shot. That has been fixed, the car is now sporting an ATI Treemaster converter, the boost has been upped to ... not really sure, but we're going to max a D1SC if the numbers are correct. - The car has been waiting for tuning for a while now, little things keep coming up.
