Oil Pressure Range

[protpibe]

Pretty much bang on with what I see. Where did you install the pressure and temp probes ?

@Dezoris Can you get a video going through the RPMs once warm and post it here?

I'm thinking I will update the first post soon with everyones data so that it can be found quicker for people looking for this answer.

Oil gallery plug.

I have a pseudo install video and more detail coming, just been buried trying to get car back together this week.

Oil pressure always correlates with oil temp.

I have the pressure gauge hooked up where the stock oil pressure switch is at and I see slightly higher pressure than that. At 198F (after commuting) I see right at 14psi. This is with Eneos Sustina 0w-20.

Went to the track today. My oil temp reached 127C (260F). At that temperature, oil pressure was always less than 3.0 bar across the rev range till redline. I set my oil pressure gauge to beep when pressure drops below 3 bar. It was beeping almost the whole time while lapping. It would sometimes drop to 2.5 bar (36 psi) during gear changes or at the corners. Definitely not good. I'm already running 5w30.

I ran I to the exact same thing, which is why I have an FBM oil cooler on the way. I I have a track day on June 6th and I'll post up the difference it makes in temp and pressure

I already have a Perrin oil cooler and Koyo radiator. Imagine what the oil temp and pressure might have been if I didn't have an oil cooler. My car is also supercharged, which undoubtedly contributes to the high oil temp

Oh I didn't even realize. What was the ambient temperature ??

This is the issue we don't really have much data on whether or not this is normal. With the car running 0w20 from factory we already know oil temp ranges run from 190 to 225 on the street for a stock car. Spirted driving you can expect 230 easily which means preasures would always benin the 40-60 psi range based on your data.

Either this is by design or oversight. But I have to say when I had my 2-3 hour track session oil peaked at 265 with cooler, UOA was perfect.
So I can assume pressures were as low as your and no wear materials in oil.

We just need to get more people involved again. Maybe guys like CSG, Robi and Evasive. I know @Dave-ROR had logged pressures as well. Lets see if we can get a bunch of data and make a FAQ post.

I got my gauge installed yesterday. I noticed my pressures tend to be higher than what most are reporting here so far.

They are definately higher until you get plenty of heat in the oil.
When my oil is around 170F pressures are still like 50-60 at 2000rpm.

Hmmm. Alright. I'll just have to do more testing and see.

Ambient temp was 36-38C (98-100F). It was really hot.

I also watched the oil pressure gauge during the 110km drive home. With oil temp at 92C (197F) and cruising at 2700 rpm in 6th, oil pressure was around 4.0 bar (58 psi) with the 5w30 oil.
