    Been think (always a bad idea in my case) about your concern of heating the air before the radiator (if installed in the outflow area).  While there is no question there would be some heating by such things as the turbo, etc.  I am not certain that it would significantly effect the air temperature, particularly in flight. 
 
Hi Ed,
 
Thanks for the comments.  I think this all boils down to how long the air stays in the cowling.  If we try to slow the air down to minimize drag, the result will be hotter air going into the radiator, so it seems obvious that having the radiator at the outlet of the cowl will never be the best situation.  It might still be perfectly acceptable, but I just can't say.
 
Cheers,
Rusty
