What computer are you running ?? Check that you temp gauge output is setup properly.

I don't want to start a debate on that but from my personal experience I had better temp running a fmic at the track then the water to air as it would heat soak like crazy between session. Only the first session of the day would benefit from the water to air setup.

When installing the fmic did you try and save the oem "ducking" for the rad or was it destroyed in the process

Oh !! One other thing ... Get a oil temps and pressure gauge !!!!!!!

 

Thermostat I need to check out to see if it is stuck in anyway.

I'm running aem v2, temp gauge settings were never touched. I don't have any of the ducts for the radiator but I'm thinking of creating a duct scoop to bring air to it

 

Have you recent done anything with the coolant? Drain, flush or replace? Installed the koyo prior to the track day?

 

I realized I had a few air bubbles so I bled it while at the track. It helped a bit but I still had heat issues after a few hot laps. I am running water + water wetter.

 

Aren't aem temp values off from oem ???

 

This.

Unless you have a proper gauge to monitor oil temps, you're likely killing your oil prematurely.


OP, do the following:
- flush your coolant, do distilled water and a bottle of water wetter. This will help with coolant temps.
- add an oil cooler. You could also run heavier oil to help with oil temps. Lower oil temps will help with lowering coolant temps as well.

I'd also add some monitoring... find out what your oil and water temps are.

 

Before I ran my oil cooler i would beat on the car with 25-30 minute sessions and only go to 4 bars near the very end. Ambient temps 95+. You shouldn't be getting that hot. This was with a stock radiator too. (this was running pump. Running e85 i would never get hot on track no matter how long the session)

If everything checks out i would look at the OEM serpentine belt and tensioner. I had a buddy with all you same symptoms only getting hot at wot. turned out his water pump was slipping on the belt. He had let it go some time and it was very stretched.

 

IMO i don't think your system was fully bled, it takes forever to bleed these cars

The car has oil temp, trans temp, diff temp. intake air temps pre and post intercooler, egt's etc monitored via motec.
Oil temp peak over 20 minutes 255F. coolant peak 175F. ducting is very thorough. ambient 77f. post intercooler peak 92F.
transmission 194f, diff 240f (died next session). collector egt 820c.

 

How is your ducting set up?
