Oil Cooler for 0235 C-1

I have a RV3 with 0235 and the standard rear baffle mounted Vans oil cooler.
When I installed engine and oil cooler I just drilled a series of 1/2 inch holes
to let air into the oil cooler and keep the rear baffle strong expecting to enlarge inlet if needed. I also went with a spring and plunger instead of
vernitherm. I am now wondering if i need a oil cooler at all. On a warm day
(temp in 80's) I barely get 175 and only during a long flight. I put a total block on the rear of oil cooler and on a slightly cooler day (around 70) get only about 180 to 185. Does anyone have any experience/advice who have
had a RV3 with the 108/115hp 0235's.

Thanks

Sounds like you have found a good setup, how long has it been flying like this?

I have 22 hours since I put engine on a engineless 200 hour airframe. My
concern is too low of oil temp not burning off water that condenses in engine.
During hot summer days which i haven't flown in yet may be about right. If
I could remove oil cooler and get a 200-210 absolute maxium I would consider it.

You could put a sliding shutter in front of the cooler, inside the baffle.

Would be a pretty simple project, and then you will have control of temp if you get someplace hot.
