I almost had a heart attack today. I nailed the gas on a little straight away today. I was 2-3 seconds into it and noticed the oil pressure coming up from 30psi to 60psi. I let off of it and it stayed at 55psi. I am thinking what the hell is it doing down around 30 psi anyway, especialy after 2-3 second of high rpm. Stoped car and reved engine and pressure stayed between 50 and 60psi. Dropped it in to gear and hit it again and the pressure dropped to 30 psi and then back up to 60 psi. Lots of things ran through my head and then maybe the g-forces are pulling the oil away from the pickup tube? It is in the middle and not in the back. Checked oil level and found it to be 1 quart low. Added the quart plus a half for good measure and the problem is gone.
The problem with an expensive motor is the worrying.

How did it get a quart low already?

Not really sure. There are a couple of drops hanging from the oil pan but no oil on the floor. It must have been a little low to start with, dripped a pinch, and 5 runs at the track with the motor recently been thorn down and resembled, maybe burned some?

Wait till you feel it go "soft"at 105 mph........

It is not unusual for a new motor to burn a little oil until everything gets "friendly" with each other on the inside.

You were definitely uncovering the pan pickup. If you are using a stock pan, they are marginal when you get to high accel motors. Try to make sure the pickup just touches or is barely above the floor when assembling, and I angle mine towards the back a bit. I build custom pans for my cars with baffles and such for g-forces in all directions.

Do you have some pics of the pans and baffles?
