Does anyone have a rough idea of the frontal area needed for a 1-1.5 inch
thick oil cooler for a 13b?  The Velocity puts a ducted oil cooler up front
with a NACA duct.  I'm not sure if the airflow would be sufficient or if you
could fit a large enough cooler.  I was thinking of putting something
(properly ducted) more directly in the airflow on the bottom of the nose (in
the area where many mount a landing light).  This is then used for cabin
heat off the duct, and should not interfere with the fixed front nose gear.
Any ideas?

Thanks, Marc

My guess is 25% of the "frontal" area of the rad Marc.
NACA does not recommend using NACA duct's for radiators.
