The fluctuation on the brakes is pretty typical. I run an oil accumulator for that very reason. I have ran 3 different pans and have had oil control problems with all 3. I didn't want to have to be concerned if I got on the brakes hard. David is right about the oil running away from the pick up.

You added that you didn't notice it until you lifted getting the car straightened out. Sounds like maybe the oil was moving away from the pick up then. Did you see the pressure drop under power, going straight, at the finish line on another pass?

Yes, I did I started watching it going down track the pressure was getting down to around 20 to 25 psi on every pass. I beleive I made 5 more passes and it droped every time.

Is the oil pick up welded to the pump and does it have a brace from the end of the pick up to the pump?

Maybe it fell off the pump.

Sounds like oil pan issue, trap door, or nothing to keep the oil from running up the back of the pan on acc..

Its a mechanical gauge. The pick up has a bracket on it that bolts to the pump housing I can't remeber if I welded it also.

Re: oil pressure drop
 

A very real possibility.

sounds like I need to pull the pan and check and I may try anther pan as well can you guys recomend a a good pan with a kick out sump an a 7 or 8qt capacity

Moroso with built in screen wiper.

JMO

Zip.

I am also thinking of changing the pump while at it what is your thoughts on this? Should I wait and see if the pan fixes the problem and would switching from 20W50 VR1 to 10W30 make any difference? I know the folks on here have more experence and knowledge than I do. I just want to make sure I cover everything.
