another oil temp question ... Options

[SirAndy]

sooooo, i decided today to hook up the stock oil-temp gauge (the little one without numbers).

i tested the gauge (werks fine), i tested the wire all the way back to the sender, werks fine too.
i could NOT test the sender itself (duh, it's *IN* the engine right now).

then i took her for a drive, ran some errands, just around town, for about 30 minutes, no freeway or otherwise particular hard driving.

my question is:
what kind of oil temp should i see on a 80 deg. day after 30 minutes cruising around town ???
anyone here who can give me any references? (IMG:style_emoticons/default/confused24.gif)


the needle barely made it about 5mm to the right of the first white stripe.
that would indicate the engine wasn't even up to operating temps.
can this be right??? oh, forgot to mention, the thermostat is removed, full airflow to the oil-cooler at all times.

thanks,

My experience...

Converted a 911 dual gauge to read in deg F, so I made a new face that went to 300deg F, matches the 150deg C that the factory gauge had.

Bought a new VDO 300 deg sensor that fit our taco plate, think it was 14m thread.

First time I ran the motor, the direct reading gauge on the motor (dipstick) was reading 50deg less than the panel gauge (IMG:style_emoticons/default/confused24.gif)

Called mainley who makes the direct gauge and he said its simple to test, put it in boiling water. I did and it checked out perfect at 212 deg F.

VDO tech said that their newer 300deg sender has different ohm rating than the older one used by porsche. He said they actually make 3 different 300 deg senders, all with different calibrations. We are kind of stuck with the one that fits our plate.


So I calibrated the electric gauge to match the direct gauge and now they seem to agree.
