Gerard,
From what I've told (Advanced Pilots Course) aluminum has lost a significnat
amount of its strength at the CHTs you are showing on Cyl 4 during climb
out. I use 380F as a target, 400F as my limit, and start making drastic
changes if a CHT gets to 410F. I would not only look at more cooling air to
number 4 but also more fuel. You didn't mention whether you were climbing at
full rich, or had started leaning.

Since installing an EDM 700 I notice my cylinders running around the 380 to
415 deg C

Number 1       380 deg C
Number 2       380-398 deg C

Number 3       380-395 deg C
Number 4       415 deg C

Number 4 reaches 430-450 in the climb out at 130 KIAS

I am thinking of putting 2 NACA ducts in the top cowl to address
particularly NO 3 & 4 temps

What say ya'll

Gerard
