There is quite a bit more but here is the key
    
part.   Use an extra 
  
airspeedindicator to measure the pressure at
    
various places around 
  
the heat
exchangers, especially the 'front' side.

    

Tracy, this is just such a way cool idea!!  It
wouldn't take much work at all to run a bunch of
temporary 1/4" ID platic tubes to points all over
the plane and cowl, with the ends all terminating in
a nice row on a block of wood.  With a brass insert
fitted to a piece of tube coming out of the AI that
would allow the AI to be switched between any of the
various ends, a survey of relative pressure across
and within the entire ship can be made in a single
flight.
