Anyone out there ever experience oil pressure dropping to about 10 lbs just after the car passes the 330 ft?
I am out of ideas.
Once the pressure drops, I lift and it will recover right away and I can finish the run with 60 lbs pressure.
Oil pressure is 40 lbs hot at idle no problem
After I saw this I pulled the motor, changed the pump and pickup, went back to the track made a pass and the same thing happened.
I added a qt oil, same thing, added another qt. same thing.
7 qt pan and I usually run 6 qts. ( one in the filter)
Changed the guage, same thing happens.
SBC with moroso eliminator pan 8 1/4" sump. using a Melling pump and pickup.
Any ideas out there?
