Following research and many calculations, two (2) Diffuser Ducts and Nozzles (blue) located under each wing, were designed to cool the Turbo-Intercooler and Water Cooled Engine. 150 mph air enters the diffuser, and is slowed to 25 mph with an increase in static pressure, as it enters the radiator. The warmed air is, then, accelerated to 125 mph before exiting just in front of the mt-propeller, variable-pitch propeller.

A third Oil Cooling Radiator is mounted at the belly mounted NACA Duct’s outlet, as depicted below.
