EJ251 | 5w30 full syn.

I'm seeing some pretty low oil pressure values at warm idle (<10PSI) and I'm considering trying out a larger pump to ease concerns.

Has anyone using these larger pumps experienced any adverse effects?

Why 11mm and not 10mm or 12mm units? I see that the 10 and 12s have a higher bypass pressure. Perhaps this is a reason to stick with 11mm units?

?

What normal cruising PSI ranges are you seeing? If the bypass pressure is being reached frequently I could see where cavitation concerns might be warranted, no??

Any input or thoughts appreciated.??
