I'll  take it a step further. If I were Power Sport I would scrap
the current set up, use the stock cowl  and copy Engineair's cooling
system designs. EngineAir came in second again this year in the NC to OSH
race at something over 300 MPH as I recall.

Unfortunately there is no room under the Power Sport engine due to the
internal spur gear reduction PSRU lowering the engine for a single radiator.

Don't even think of running the rotary upside down :-)
