It occurred to me that the problem with the Type 3 cooling air system 
(if there IS a problem) may be the length and size (conductance) of 
the cooling air intake channels. They may just be too small (too much 
pressure drop) for a much larger engine. The pressure drop would 
actually be fairly easy to measure. Might be interesting, and then it 
could be compared to a beetle and a Type 4.
