Last year I was seeing 220-225F max on coolant temps which I was okay with. This year went E85. Since last year I moved my oil cooler to give it cleaner flow but it is center of my radiator right in the opening. My oil temps have been good, about 210-220F, much lower then before. My water temps where hitting 240F at around 85F ambient. Went to a Koyorad, still seeing 230F and sometimes still approaching 240F water temps during longer sessions 80-85F ambient. I am thinking more hood ducting and moving my oil cooler over to behind one of the fog lights. I haven't really heard too many complaints about water temps NA so I am kind of surprised by this. Again, other suggestions welcome.

Something is wrong.

Are ***all*** factory shrouding pieces present? Age of the car?
