100 degree heat with an air cooled engine

Popgun, I believe Trail Tech offers three different sensor sizes. I think the the middle size should work best, but to be sure, get the smallest. Where talking about the "size" of a copper bar - attached to a thermalcouple and cable back to the display unit - that wedges in between the fins on the cooler. The "size" is referring to the width of the bar, not the thickness or length, You want the size to be a tight fit, but not so tight that it overly stretches apart the fins inside the cooler. It might even be a good idea to order all three sizes so you can find the ideal size to use. 10mm may be a bit too large for our oil cooler fins.

The sensor comes with tube of silicon rubber compound to fill in the space around the copper bar wedged in between the fins and helps the sensor stay in place as well as insulating it from the "cooling effect" of residual air flow in that location of the cooler.

Instead of pressing the copper bar in between fins, I devised a way to anchor it down "ON TOP" of the flat surface of the cooler. However, it is important even more so to "shield" the sensor in that location from the air stream. Regardless of where you mount it, you want it to be in direct contact with a high temperature surface area of the oil cooler, and which ever way you go, to be well insulated from outside air as much as possible.

If you get this device, please post your observations to the forum. I'm sure some others here will be interested. Thanks!
