27.4 69 48
34.9 69 48
36.9 70 46
46.3 65 48
59.8 66 49
67.7 68 47
70.6 65 35
So they look pretty consistent until the last
flight.
I haven’t checked the sender.
I did do a rewire of sender wiring. I will check
this however the pressure at Take off was within the range of
previous temps (Lowest of the previous readings)
Can anyone comment on the reasons and their
probability for lower oil pressure?
I believe the Renesis 4 port has only one oil
pressure regulation valve.

Hi guys
I’ve just noticed that my oil pressure on the last
flight dropped lower than ever before.
At takeoff 7000 rpm with an oil temp of 71C (160F) it
peeks at 65 psi (according to the sender) then drops off
as Oil temp peeked at 100C (212F) with a pressure of 35
psi.
During the flight as the oil temp dropped to 86C (187F)
the oil pressure was then 55 psi.
Pressure appears independent of rpm and closely tracks
oil temp.
I can’t recall the weight of the oil I’m presently
using.
Engine is a standard unmodified Renesis 4 port except
the mod to replace the thermal pellet in the e shaft.
Would appreciate your thoughts and numbers.
