Stable Oil Temp

[terbang]

Just as a prelim, I just installed an oil cooler to my 1100 EZ. I managed to lay my hands on a GS 550 cooler which is a nice compact unit. I also managed to lay my hands on an oil thermostat. It regulates to 180 F (around 85 Celcius). Inserted a restrictor into the oil gallery that feeds to the filter chamber, reducing it to 4mm and plumbed it all up with 3/8 hydraaulic fittings. Just took it for a local fang and the oil temp came up to exactly half way between the 70 and 100 mark (looks like 85C to me) and remained stable there. Previously it would sit around 100 and often higher..! .
The inlet into the cooler is hot and the outlet is much cooler. YaY at last a stable oil temp in a sensible range...
More to come as I refine it....

Sounds good, but isn't 100 degrees where it starts to boil off the water-based contaminants?
Any idea what the temp is going into the cooler, now that the cooler is installed?

It has been many years (24 or so) since I have run with an oil temp gauge on a bike, and it was a big, water-cooled touring bike, so the numbers would not necessarily correlate. In my 4-wheeled vehicles, I like to run the oil around 220-230 to assure the water is boiled off. (None of them have had a cooler, though.)

He said celsius.:-|

Sorry to have mixed the readings, there. My 220-230 should have been noted in Farenheit, which is 105-110 Centigrade.

The question still remains...why cool the oil to the point where it no longer boils off the condensation?
