Gauge Range suggestions Temp/Oil Pressure

[garner]

I'm shopping for gauges and I wonder what range I want for Water temp and Oil Pressure

 

What is normal operating Temp?

 

What is normal operating Oil Pressure?

 

Basically, I'd like to pick ranges that keep the needle somewhere in the middle during normal operation

 

thanks in advance for the advice

 

btw, we're talking EA82T here

I have an Autometer oil pressure gauge, the gauge goes from 0 psi to 100 psi, 25 psi increments when cold the gauge will read 75psi and drop to 10psi while idleing, (warm). A general rule for oil pressure, that I have heard, you should get 10 psi for ever 1000 rpm so at crusing speed I am right on with rpm 2500 with 25 psi. So the gauge reads to the left of center at crusing. but if you want it to read in the center just drive around at like 5000 rpm. just kidding, I had a vdo vaccum gauge that was pretty good jsut incase you want something other than autometer

Thanks Subi81,

 

So the 0-100psi aught to do it...

 

Another question, I understand that mechanical gauges, especially for Oil pressure are more reliable and accurate.

 

Can I use a mechanical oil pressure gauge and maintain the stock oil pressure idiot light. I love idiot lights, there just my style

The EA82 pump has two ports. One is used for the anolog guage and the other is used for the digital guage. You could probably use the extra one for the aftermarket unit.

I'm running mechanical oil and temp guages made by auto gauge. My '86 wagon is a GL and I have a stock oil press guage, no light. I ended up tapping out the threads for the idot light in the oil pump to accept the aftermarket guage fitting (1/8 NPT). You could do the same and run a "T" fitting for both guage and light. I'm running 60 psi at 3000rpm and the temp sits at bout 205

F. Good luck.
