   Paul,
      What is the size of the radiator in this drawing.

   TIM Holt

   The core frontal area is 470 square inches. If it is 2 inches thick
   it would give a core volume of 940 cubic inches. About right for
   a 300 HP 3 rotor. If you want to go to a 360 HP p-port 3 rotor you
   night have to increase the height of the rad to about 20 inches
   from the 16 inches shown which I think should still fit in
   the stock cowl. An RV10 with 360 HP at sea level would be
   a real nice 250 HP cruiser at 12,000 feet.

   Make sure you plan for cowl flaps.

I gather the airflow would be outboard-->inboard through the heat
exchanger.  And then where does the air go?  Down and then out?

Looks good.  Interesting asymmetry.


Matt-

It has been done that way but the best way is from the inside out IMHO.
Less back pressure on the rad and the diffuser duct insulates the rad
from the under the cowl warm air.
