First some background on the car;
Currently in Arizona it's 100F ambient. I have seen coolant temps on my display at over 210F and thought that maybe the thermostat was failing so I ordered a Stant (part number 48227) which didn't fit. So I put the original back in. Filled and bled the system (twice) and still have high temps, or at least they seem that way to me. Maybe because I now have a digital readout where before the OEM gauge stayed pretty rock solid. Took a drive and the coolant temp ranged from 192F to 200F, depending upon moving or stopped at a light. Oil temp was between 205F and 220F. Ambient temp was 100F. So some questions and possible fixes;
I'd like to get the car back on the track but I don't trust coolant temps yet. The intake shroud is tight against the radiator and the OEM fan and shroud are in good shape and working. Just wondering if there is something simple and not too expensive to correct this problem. That is, if there even is a problem. I guess i could;
I'd like to get this done sooner than later and with as little money as possible. Looking for Hrant, RYU, Coz and DocJon for some assistance. Thanks in advance.

- SOS WTA intercooler mounted in standard position in front of the lower radiator
- OEM radiator replaced last year with new Koyorad radiator and running Honda Blue Coolant
- Current horsepower is 450 on pump and 525 on E98

So some questions and possible fixes;
- Maybe now that i can see actual readings, don't sweat it. This is normal? What temps do you normally see on a warm day?
- Could the t-stat be stuck partially open? Takes around 8 minutes at idle to warm up to 185F and then settles between 192F and 199F.
- Radiator fan kicks on at 195F. And if the AC is on, the radiator fan remains on, even if the coolant temp drops below 188F. Is this normal?
I'd like to get the car back on the track but I don't trust coolant temps yet. The intake shroud is tight against the radiator and the OEM fan and shroud are in good shape and working. Just wondering if there is something simple and not too expensive to correct this problem. That is, if there even is a problem. I guess i could;
- Move the intercooler farther away from the radiator with spacers to give more room and possible air flow to the radiator
- Replace the thermostat regardless
- Replace the OEM fan and shroud with a twin SPAL fan and shroud with a new 40A fuse
- Replace the relatively new Koyorad with the latest MASIV
- Install an oil cooler
