Bit of a bummer to be honest.
Last session of the day I turned the heat on full and vented it out the passenger side, and my coolant temp didn't go above 240. I was able to run a full session like that, but I'm obviously uncomfortable with this amount of heat.
As an observation; a new Civic type R was also having heat issues, but that's nothing new. None of the other factory turbo'd cars at the track were doing limpy laps other than an STI.
I *thought* the dual radiator kit would work well but I'm wondering if it was a mistake to purchase it instead of the standalone oil cooler.
I'm looking for any ideas on how to reduce engine oil and coolant temps. I've thought about:
- venting the hood, but I'm trying to keep the car pretty low key exterior wise, and I'm doubtful it would make a big enough difference to be worth it
- changing coolant
- switching to a JR standalone oil cooler
- wrapping the stock header, not sure if this is even possible? I haven't looked at it yet, but usually oem headers don't have a lot of clearance for wrapping. I still have the oem heatshield so it would have to come off - not sure what decrease in temp I'd get
Overall I feel that there likely isn't one solution here and its probably going to be a combination of multiple fixes to get the temperature down, I'd also like some feedback if I'm going to put a ton of effort/time/money into trying to solve this issue and it might not actually be solvable.

I'm also dealing with very high oil and coolant temps. I'm running the dedicated JR oil cooler with the setup integrated with the intercooler and rotrex cooler.
I saw 262F oil temps during a similarly hot track day this weekend. Really frustrating as I though I'd be rock solid in terms of heat management.
