VMS Temps
After completing an 1100 mile trip to Nac today, was curious what everyone considered normal for temperatures.  About the highest ambient temp we encountered was 95.

Retarder - 185 to 190
Trans Temp - 180 to 190
Coolant - 178 to 188
Manifold - 85 to...

This look OK Mark,  Coolant is in the range, transmission about + 10 degrees from that, retarder another +5 degrees.  Volts are good.

Retarder can easily go much higher when it gets used.  I like to try to keep mine at 235 or less when I can.  On...

What is high for manifold temp. I was reading in the Silverleaf pamflet that the manifold temperature can tell a lot on how hot
the engine is. I need to know as it doesn't look like there is exhaust temperatures.

My intake manifold temp consistently runs about 20 degrees above ambient which I believe is considered normal. Have never driven in temperatures below ~40 degrees so can't comment on what that might look like.

High intake manifold temp would...

My intake air temp runs 10-15 degrees over ambient air temp

I missed Manifold temp.  That is incoming air temp after it goes through the turbo and then the charge air cooler and is going into the engine. About 10 degrees above ambient is good.  I have seen it higher than that but only on really hot days. ...

I know this is a "temp" topic, but on my trip this past weekend, my VMS was showing oil pressure at 19-20 PSI when idling at a stop light (in the yellow).  I checked the oil and it was full.  Is that a normal idle oil PSI?

Mine showed 15-18 psi at idle it's fine

19-20 PSI when idling

And the book on my 97 8.3, for example, lists the minimum acceptable idle pressure as 10.

I had last winter driving up a long hill in around freezing weather on the dash a high manifold alarm, as soon as I took my foot
of the throttle the light went away. I had just started the engine below the hill so as Steve said the fans would...

Thanks all, the numbers are reassuring.  Special thanks to Roger for setting me up with the VMS. After having and using the System, I can't imagine myself without it, and yes Roger, I like being able to just glance at the greenlights.
The guys at...

I think the key with VMS is that the moment something goes awry you have a chance of seeing it.  If your oil pressure is suddenly 32psi instead of 36psi while cruising down the highway it's a good bet that something is horribly wrong.
