WHAT is MORE IMPORTANT OIL PRESSURE OR OIL TEMP or i am comparing apples and oranges?? What i am trying to do it not to ruin a bearing or damage anything due to oil. I am putting on a 951 S oil cooler along with the current oil cooler.

I think it is a little apple/orange, lack of pressure will do almost immediate damage as you know, I've been told to add an extra 1/2 qt. to these cars for the bearing issues.

Yeah that i do. The thing is now iam going to be doing some DE's and i dont want to run into trouble with something that can easily be mont. and prevented. i would put both however i only have space for one more gauge.

JonH

I with you, in the same situation. Everybody I've talked to says other than opening up the bottom end for crank or pickup mods, a little extra oil is about all you can do to help. As for gauges, I would run a pressure gauge first, again to prevent those immediate problems that pressure drops would cause! If you add an extra cooler I would just let it do it's job, your doing about everything you can do for a street/DE car.

Both are important.

Since the factory provided you with an oil pressure gauge, I would say that the Porsche engineers feel that oil pressure is more important and I would agree. So if you are looking to add a gauge, I say add the oil temp gauge.

You can kind of tell that your oil temps are high from the pressure gauge, as the oil pressure will drop when the oil temps get high. But this is not the best method to determine if the oil is too hot and breaking down. Typically oil temps that exceed 210-220 degrees, will cause the oil to break down.

This is what I will be putting in the M3 since I only want one gauge but would like to know both Oil Temp/Oil Press:

Is the factory gauge accurate like the boost gauge???

When my oil temperature went up, the oil pressure went down, especially at idle.

Interesting but digital i have to sleep on that one only because the only digital guage i have is the narrow band. However your guage is growing on me as we speak.

It is accurate enough to let you know when you are in trouble. Not accurate enough to watch bearing clearances open up, but then who needs that level of accuracy.

Meant to post this better pic.

How do you like? How was installation?
