I think 140 on the climb is very slow, Tom. I suggest you set your climb speed at 165. That should still allow 1500 to 1800 fpm vertical at least to about FL 180.  The bonus is that CHT should be a lot cooler.

I have been fighting for over a year to try to keep the #2 CHT below 400 dg on the climb. It has hit as high as 430. I leave it full rich and climb at 140kts. When I level off, I then LOP and then #1 cools off. I have the Lancair baffles and RTV the gaps with the engine and have a good baffle seal. I even covered my 3rd intercooler and that only helped a little. Behind the prop the baffle seals up to the top cowl but not down to the bottom. I have seen it the reverse of that as well. If close the oil cooler door the CHT will drop 5dg at times. This was a factory new engine. Any suggestions?
