Paul,

<<1.  My  oil temps ran 250+ (red line) until I did the following--I put
a naca scoop in the center of my top cowling with a 3 inch flex tube to
the oil cooler and closed the 3 inch hole behind # 3 cylinder.  My temps
now are 185 to 190.>>

What impact did fix number 1 have on CHTs in cruise for the various
cylinders (@ full throttle and leaned for best power)?
Chris
