This is just for information purposes. 108k miles on stock oil pump, idle vs 1500ish

This is the same time and test but with the oil control valve turned off.

[bishopts]

2500rpm with the valve turned off it will hit 60psi. The question I've been wondering is if i left it turned off would the higher pressures break things?

No, but it will wear quicker since the engine oil wont be filtered anymore.
The Bypass in the oil filter opens. So don't do that.

This is a different bypass valve. Its the oil pressure regulator valve in the oil pump. Its what limits oil pressure on our engines

Yes, but if your oil pressure is too high then the oil filter stops filtering.
Oil pump sucks oil from pan -> high pressure through the water to oil cooler I believe and then through the oil filter which will bypass if the pressure is too high.

Ah i see what you mean. I need to find that pressure limit.
The pressure is regulated for fuel economy. Less parasitic draw from the pump, kinda like how the alternator turns off for reducing unnecessary drag.

Gotta find that balance to stay under that threshold. But first figure out what it is.

Oil pressure has to have a differential of like 16 psi between before and after the filter element to open the bypass. That can happen on stock pressure ranges if the filter flow rate can't keep up at higher rpm or cold flow. So uping oil pressure isn't really going to affect that aspect any more than temperature will or filter age or rpms.
If your flow path is pump>cooler>filter>oil galley>bearings/lifters and your bearings have more restriction than your filter , the pressure differential between before and after the element will be minimal if anything at all.
The only way it will bypass is if the filter cant flow what the bearings need. Which would be a problem that needs to be addressed on its own. If the pump is putting out more than the filter can flow it will still flow what the bearings need. Otherwise the stock pressure would be limiting the bearings too.

For myself I would not mess with it, you probably will increase wear of the stock pump and if you already have 50 psi at 1700 I would not try to spin to 6k.
I am 99% sure Oil gets unfiltered. You are literally creating a high rpm WOT scenario but are just at like 2k rpm in terms of oil pressure.

If you did not know you can slightly lower the High pressure RPM threshold with HPTuners so you really have more oil pressure sooner and when you actually benefit from it.

Yea that's what I've been looking into. "What would you gain? "
More stable lifter operations , especially if it's a DoD system.
Tighter oil layer in the cam and crank bearings
Less slop in the vvt system.

But then the drawbacks are there too.
More strain on the pump control valves.
Oil coolers seals could develop leaks sooner.
Rapid changes in throttle are more likely to make the filter bypass.

The whole reason i even started thinking about this was, i watched my idle oil pressure drop lower than off idle pressure. I know that's a pretty normal thing, but with a electronically controlled oil control valve you would think you could have a constant oil pressure no matter the rpm. Basically a wastegate style control for oil pressure.
