408 cubic inches is short of the 600 to 750 that are being used
successfully.  I posted my a/c core sizes yesterday - 336.65 cubic inches of
fin area X 2 = 673 cub inches - that will be enough.

Subject: [FlyRotary] radiator


Hi, fellow rotary enthusiasts.....I'm getting ready to order a radiator for
my 13b powered SQ2000 canard pusher.  I talked to Al Wick, and he has a 160
hp Subaru powered Cozy and is cooling it very well with a radiator that is
17" x 7.25" x 3" deep.  Any idea if that size might also cool a rotary?  How
does that seem to compare with two GM evaporator cores?  I was told that if
I can increase the height to 8 inches instead of 7.25, they can put two fans
on it, as well as the built-in Meziere EWP. I can work with the additional
height of 8 inches.  Just don't want to spend $1100.00 for too small a
radiator. If 17x8x3 equates to approximately the same size as two evaporator
cores like Ed Anderson is using, I should be OK. If anyone can compare the
square inches of the two, I would sure appreciate it.  Thanks in advance for
any and all efforts and recommendations.  Paul Conner
