Do you know what is inside the Canton unit that could allow the oil to heat up to the 170 degree range while idling ? Sounds like there is some type of orifice that they force the oil to go through . GPM through an orifice equals pressure drop equals heat generation ... and in this case , it sounds like a good thing ( here I`m being an anal engineer again).
I went for a drive Sunday ( 80 degree day ) and never got over 160 while cruising . Robert didn`t sound too concerned about being below 180 to 200 degrees on the oil .
I also went to Canton`s web site and couldn`t tell what was in the unit .... however , depending on your outcome , I may have to get one .

Here's what I think was going on with my previous setup and why the canton unit helped. It is true that with an Aluminum motor, its hard to get the oil temps very high. The block is a good natural disipator of heat and the fact that most folks don't paint an aluminum block only helps to improve its ability to disipate heat. The cooler has alot of bare aluminum serface area (fins, top and bottom supports, and the aluminum duct work in the nose) as well as a long set of lines running outside the hot engine bay area. By installing the canton unit inside the engine bay, all of the natural cooling surfaces associated with the oil cooler are bypassed and the thermostat and lines are contained in the engine bay where the surrounding air is not as cool. I think that this explains the higher oil temperatures during prolonged idle.
