When switching to 5W-30, I understand that you still got pressure drops at high RPM's. Makes sense as 5W-30 doesn't have a significantly higher cSt value above 212F (something around 1 cSt). But did you notice the pressure start to drop at slightly higher temperatures, or was it fairly identical to the use of 0W-20? What I'm trying to say is, if you had pressure drops starting around 212F on 0W-20, did you now see a change to something like 220F with 5W-30, or was it still at around the same temperature? This question may be a bit too specific and I don't know if you compiled such data.
I am mainly becoming curious at what oil flow cSt value the pressures start to drop on our platform (that is if it is fairly consistent or within a certain range). From this I could potentially start to make some correlation as to what temperatures this would occur at depending on the oil weight being used. In addition, an approximate limit of oil temperature can be determined to be ideal prior to oil pressure drops.

It was a long time ago I ran 5-30, I want to say it was similar I don't remember.
I notice the pressure drop pretty much at operating temp or above.
