What are nominal CHT's for my O290 on Spezio. I'm running too cold. I've closed the openings on sides of cowl and it helped but I don't think enough?
On a 90 degree day I'm running 375 degrees in 70 mph climb
and 340 in 90 mph cruise @ 2400 rpm. Oil temp settles @ 160
Only official data I've found is 500 degree max.
I suspect I need to modify my outlet? I'll be much too cool in winter?
Thanks, Jack
