Fluctuating oil pressure

[Purple Venom]

Been watching my videos from Putnam and noticed that my oil pressure was fluctuating, especially on left hand turns. The pressure would drop from 45-50 to 25-30. When at 25-30, I was off the gas, and entering a turn. As I rolled in to the throttle through the turn, the pressure came back up. Anything to worry about?

Tim,
The reduced pressure may have been caused by the pickup sucking a little air, but I bet it was more because the oil was heated and and would naturally drop pressure as the RPM declined. Some of the guys put in AccuSump type reservoirs to deal with reduced pressures due to cornering and rapid RPM change.

As long as you were showing 15-20 psi at the lowest, you should be good. I am assuming once RPM was restored, it climbed back up?

Does your motor oil pan have an increased sump or is it a stock pan? Is the pan trapped and sumped for road racing, drag racing or street driving - all are different. How many qts? Is there a windage tray installed? Was the motor block relieved / coated to improve oil return flow path? Lot of things that are normally passed over for street motors.

Motors like nice, constant, steady load. Doubt that was anywhere near Putnam last weekend.

I have a Canton Race Pan with baffles and trap doors where the pickup is. It's almost impossible for the pickup to not have oil due the the construction of the pan. It's a front sump pan which is T'd, holds 7 qt's. There is a tray built in to the pan, but not a windage tray with scrapers for the crank.

If your normal idle oil pressure is at 25-30 and your acceleration pressure is at 40-50 everything is fine. Your pump doesn't know you are in a corner. The up and down of your pressure is normal - as long as it's not too low.
