Thanks for the comments. I appreciate it. The water temp only gets above 80c with a full power climb to altitude. Oil temp is in the green but only just. I can block the air intake off of course. I have limited the air intake at the front of the cowl by 50% as that is only air for the cylinders and carbs. (carb temp is about 24c) t I'm going to wait for summer before I make any other alterations. see what its like at 30c

From the photo (on its side) showing cowling/air inlets it looks like you may have overdone the incoming air. What do the top/bottom scoops feed air to?
On my last aircraft, ATEC Zephyr/912ULS, I restricted exit air during the cooler months. I just made up a very light weight aluminium plate that covered about 80% of the exit air hole. Probably went through 3-4 versions (started large & progressively reduced plate) until I was happy with all the temperatures.
Yeh! In Australia we really need to focus on our long hot summers, with some sort of fairly easy winter flying temperature fix.
