HELP High Oil Temperatures
I am going to post this in a couple places on here but any help is appreciated. I have a 2003 Z06 that I bought last year. It has 24k miles on it. I am tracking this car and before I took it out(I did drive it back from Baton Rouge to Omaha and oil was just fine), I had a DRM external oil cooler and tranny cooler installed. Both are sitting in front of A/C condenser. I ran Amsoil 10W30 racing oil most of last year and my temps with a 20 minute session would get up to 270 to 280 degrees in 80 to 90 degree weather. So that is very high for having that set up. Over the winter, I went ahead and left in the external, and added the DRM radiator with integrated oil cooler. I took it out last weekend on a 80 degree day and still hit 268 in the afternoon. I am very perplexed. I noticed after I got home, my air dam was a little loose, so I fixed that. My other thoughts are move tranny cooler to the rear and center oil cooler, switch to 15W50 oil and just deal with temps, or spend another $1k and get louvered hood. Thoughts? I know everybody else here that talks about either setup runs 240, let alone having both. Thank you for your help

Check the coolant level in the overflow tank. If you have a crack in the nipple that the hose connects to you may be losing coolant causing the increase in temp. Any chance you changed coolant recently and may need to burp it?
Run some high pressure water through the radiator and check for debri that gets caught up in it and verify fans are working.

Based on responses I am getting on my other thread, I may be asking for too much. I am running this weekend and I fixed my airdam and I have some water wetter. So will try each one one day and see how each one effects it. Problem is temps are only supposed to be a high of 70.
