It's a pretty fresh rebuild (< 5K miles but almost 6 years ago.), 3 or 4 track events; but I don't drive it much anymore (sadly) and it has shown it is a true Porsche air-cooled motor (an ever so slight leak at the oil return tube). Unfortunately, it set idle for a while during my mom's hospitalization.
Oh, and I have a massive MOCAL mounted in front (not fender) that keeps oil < 210 at track temps. Generally right at the 186 mark when thermostat opens. So no oil temp issues here.
