Quick Question.

Installed the temp probe of my Quad Adrenaline into the oil filter housing for engine oil temperature, just wondering what everyone else was seeing for oil temperatures. I dont imagine a lot of you have engine oil temp guages, but just wondering what the bench mark was. Mine runs about 10-15 degrees hotter than the water temperature at operating temps, or about 195 degrees when the water is at about 185.

I had an oil temp gauge for awhile and got the same readings as you, constant 15° above water temp. I found the gauge to be very boring as it didn't change much and since my gauge read from zero to 300° ended up installing the probe in the the air horn for air intake temp.
Much more interesting...

That's interesting. I've thought about installing an engine oil temp gauge before. But did the oil temps. fluctuate with the water temps?

wcb,

To answer your question, very little. Once it reaches the mid 190's it pretty much stays there and thats it.

Infidel,

I like your approach to finding entertainment on long road trips. So what kinda temps do you see in the air horn? Do you ever worry about high "HEGT" ( Horn Exhaust Gas Temps)

Generally I see about 20-30° over the outside temp unless I'm pushing boost over 20psi. Highest intake temp I've seen is in the low 200s pulling loads over mountain passes with egts nearing 1200°.
My main concern here in Montana is too low of intake temps in the winter. This wasn't a concern until I had the gauge and saw intake temps as low as 10°F. What I've learned from reading is the optimum intake temps for a diesel engine is 50-90F. I've noticed a definite difference in engine sound when the intake temp drops below 30 or so, never checked if it lowers mpgs but my bet is that it does.
What I've done to combat the low temps that works excellent is I've have a 3" tube that connects to the vent intake at the base of the windshield in warm weather. In the winter I move the tube's intake right next to the turbo. This usually gives me the 50-90° I desire, even when the outside temp is minus 20 or lower.

Thanks for the info. Good to know.

Very interesting, so I should "adjust" my S&B so its not sucking the REALLY cold air at -40.

Thats a pretty cool idea, would be interesting to know how the mpg's are affected, knowing that the colder the air the denser the oxygen. I would imagine that there is a threshold in there some where where cold become too cold and reverses the effects of dense air.
