So 24 psig in our area would be 24 + 14.4 = 38.4 psi.
At 4,000 rpm your lowest oil pressure was about 47 psi at I believe 212F oil temp's from your other thread on the subject:
You obviously meant using absolute oil pressure as a joke didn't you....it's a good one.
It's gauge that moves the oil around, and gauge that reliefs operate at.
To introduce absolute pressure is remotely relevant to the discussion is either intentional obfuscation (look over there, a bunny), an absolute demonstration that you don't get it, or humour.
If it's not humour, then....
LoL, +1 ... if he was talking about turbo boost pressure, then yeah.
PSIG (or just PSI) is gauge oil pressure in this case. 0 means zero oil pressure, and 30 means 30 PSI of oil pressure. No need to complicate it.
