as many suggested ducting is key. my temps went down significant with just a simple under-tray.

so my oil cooler was not not enough,got to 250F oil about 2/3 of the session. the smaller core was fine at a moderate pace, held about 220 ish. I took it up a notch and had to slow twice due to temps. going to relocate it and duct it.

I tracked my turbo'd '95 for years @ around 230whp all over the mid-west with no oil cooler. My oil temps were probably regularly over 300F. Oh well, ignorance is bliss!

I did change my oil after almost every track event because I knew I was cooking the sh*t out of it.

The lesson here is ducting is critical for any sort of cooler. Anyone doing track days should take the time to at least do some simple ducting.
