Hi Tommy,

I mispoke (senior moment) about = my cowl=20 exit area, I measured it today and it is 4.5x28" which gives me close to = a 1.7=20 ratio not counting the louvers.

Ed, If your flap outlet = area is=20 3x20=3D60sq" . Your oil cooler inlet is ~24sq" and (at 1:1 = ratio) that=20 would leave only ~36sq"/2=3D18sq" for each rad inlet. = Since they=20 seem larger than that, how do you get by with the relatively small = inlet to=20 outlet ratio, that is less that 1:1?

Does this question make = sense? I'm=20 trying to redesign my oulet size to a total of something larger than = inlet=20 area which I estimate at a total ~90sq"
