What are your temp readings?
I would say anything past 230F you shouldnt run the car hard. If it gets past 250 i would be concerned about the water seals. If your running mostly water Over 240ish is dangerous. I think a higher PSI cap is a good upgrade. I run a 16 psi cap and keep my temp between 180- 220.

I wonder why you have the fans come on at such a low temp. The thermostat doesn't open until about 82C. It isn't fully open until 95C. If you are adding more cooling to the rad with the fans at 85C, all you are really doing is keeping the thermostat from opening completely. Less coolant flow through the engine means less heat transfer and higher possibility of local hot spots in the engine. Seems to me that the range between 83C and 95C would be considered normal operating temps and the "best" temperature to operate at would be 95C. That would be the lowest temp possible with maximal coolant flow (at least with the stock thermostat).
A car running consistently at 85C (climbing to 87C if I really get on it for 30 minutes) is a hell of a long way from hotspot issues.Remember, assuming that an engine is in its operating range, cooler temperatures will mean more horsepower and less wear on the engine (and less chance of knock). The FD (and most modern cars) run hotter temperatures for emissions reasons - hotter engines produce fewer emissions.

the turbos should be okay. they still have oil flowing through them and many turbos are oil cooled only. Of course i wouldnt run much boost until your car is at operating temperature anyways.
so if I took my AC out would me turning the AC button on turn my fans on??? That would be pretty cool if it worked like that.

Today in 95F weather, stop and go traffic, with the AC on, the car ran at 203F (92C). Without AC, the car ran at 194F (90C). Temps read off Power FC.

PS. I don't know how some of you guys live without AC.

But you dont even need to "take out" your AC. Go to the front of you engine bay where the relax box is and pull out the AC relay. Go back in your car, turn the AC button on and crank the **** to 2 for low speed or 4 for high speed and there you have it, instant fan action to make the heat go away
This was my second mod when i first got my fd lol. Been doing it for over 4 years. I try to be conservative with the fans though since i dont wanna blow the fan motors but sometimes you have to, and replacing them is cheap insurance anyway.
I rather replace fan motors than my actual motor LOL
