 Rather than a flippant remark,  how about trying to address the aerodynamic
issues?
 
 A simple hypothesis as to why forcing the air into a high speed (high drag)
low volume plenum reduces overall cooling drag for the aircraft - - would be a
logical starting point.

 PS.  I am rather familiar with Darryl's system as he has brought to Ada on a
previous occasion and has sought our advice on how to set the engine up in
pursuit of his Reno racing runs.
