John,

In flight Oil temp 195 F /91 C  24 inHG 2550 RPM  I'm showing 46 psi.
I have the stiffer spring and 5/8 insulated oil lines. I am taking oil
pressure
from position 7.1 and oil temperature from position 7.2.

On ground OAT 89 F / 32 C 900 RPM oil temp 110 F /43 C just before
takeoff, oil pressure reads 38 psi increases to 53psi mid takeoff roll.
After
that point , eyes out the window no more monitoring, sorry : )

Hopes this helps.
