Last year I flushed the coolant system installed a new WP, low temp thermostat, and a center radiator. I have found that below 75° F the coolant temperature never exceeds 180° C (82° C), however over 75° F it will start to get into the 100-110° C range (the zero in 180 or past it), mostly in traffic or around town.
I have found turning off the AC helps it cool down. And I drive with the AC diagnostic menu up to keep any eye on the coolant temp, you can find that here:
CB-Racing, 986 AC Diagnostics I am currently looking into wiring a switch to manually trigger the engine compartment fan and the high speed radiator fans. My next step will be adjusting the mix in my coolant from 50/50, to 60/40 coolant/water.
