Thanks Jeff. Your temperature ranges are what I informally had in mind but wasn't really sure. I'll check out the web link.

Hi Ryan, check following link for guidance … http://www.rotaryaviation.com/faq.html

General consensus is maximum oil temperature into engine, after oil cooler is 210F – this is to protect rotor oil seals.
Suggested maximum continuous operation <200F for both oil (inlet) and water (block) temperature.
My suggestion would be 160F to 190F for both as normal cruise operating temps.
