How much cooling assistance from an oil cooler

I have a Griffin Radiator that is supposed to be good for up to 600 HP, and I have a stock shroud \ high flow metal fan with all associated hood to cowl and hood to radiator core seals. I flushed the crap out of my engine (with the bottom block plugs out) until it ran clear. I have a 180 degree high flow thermostat (no difference over a stock one). Also a Milodon high flow water pump. On a cool day, everything is fine. Using an IR thermometer, it runs at about 195 on a cool day. On a hot day with the AC on, it runs at about 205 - 210. It never actually spews antifreeze, but that is a bit warm. It runs great, but the temp is frustrating.

The issue I see is that for what you have, even in the dog days of summer, your temp should be within 10*'s of the t-stat. And stay there. I wouldn't say it's overheating, but that system should be able to cool much closer to ambient than what you are getting.
