Observed Oil Pressure with a gauge

Rusty

As the title says. There has been a lot of talk on oil pressure lately. So the more info we can get. The better informed we will be. So post up. The more info, the better.

Gauge - SpeedHut 0 to 150 psi.
Sensor location - Tee'd with the factory sensor. Different location will give different reading.
Oil - Mobil 1 0w40. Different weight oil may give a different reading.
Oil Cooler - Z1 34 row.
Oil Temp when warm - 180F.
Engine temp when warm - 185F.

These are are the oil pressures at different rpms that I observed. Using 3rd gear. Giving the throttle just enough to get to the rpm and hold it there for about one minute.

Cold Start - 65F outside temp. 104 psi dropping to 48 psi after about 3 minutes
Cold Start - 82F outside temp. 93psi dropping to 48 psi after about 3 minutes.
Warm Idle - 38 psi
2,000 rpm - 75 psi
3,000 rpm - 87 psi
4,000 rpm - 93 psi
5,000 rpm - Goes to 102 psi then drops to 93 psi
6,000 rpm - Goes to 104 psi then drops to 93 psi
7,000 rpm - Goes to 105 psi then drops to 93 psi
7,500 rpm - Goes to 105 psi then drops to 92 psi
