Kelly,
After reading Al's post, I need to make a clarification on my previous oil temp information.  The 245* temps were after the cooler, at the oil filter pad, so who knows what they were coming out of the engine. 

Mark; It’s likely that the temps in the pan weren’t a lot higher, because the reason the temps after the cooler were so high is that the cooler was ineffective – meaning that the temp drop across the cooler was only 10-15 degrees.

 Over the last year I've instrumented my oil & water cooling systems so many different ways that I sometimes get confused as to what I'm reading on the EFIS & EM-2.   Presently, I'm taking oil temp readings after the first oil/air cooler, then after the oil/water exchanger (as the oil enters the engine).  I do this to monitor how well each of the oil coolers are working.  Sorry for the confusion.

Tell me more about your oil/coolant exchanger setup.  In series or parallel on each side?  Coolant side on return leg after radiator?  Typical temps before and after each cooler?  Dimensions of the cooler?

Thanks,

Al
