Wait a minute; am I missing something here?  The air coming into

and going through the

     rad is the air from outside.  The rad is not seeing the in-cowl

air, and it should not

     be a factor.  Looks like one of those great insights that is wrong

in hindsight :).

  I misunderstood what Paul said. I thought he was simply noting the
additional under cowl heat contributed by dumping rad exit air into the
cowl and the contribution this may have to overall heat load. It strikes me
as intuitively wrong to dump heated air into the cowl if it can be easily
avoided. Why not dump it overboard? If you want to circulate air in the
cowl why not ambient air? Anyway, that will teach me to reply without
reading more carefully.

  What Paul said is true if the exit is sealed to the cowl and inlet air is
allowed to pass over the engine prior to exiting the cowl through the rad.
Is Powersport still using this approach?

I was wrong Mike. Brain fade. Don't know what I was thinking.

I predict Power Sport will change that configuration very soon or they
are more stubborn (NIH?) than even I think they are :-)
Here is a picture of that config for the new people.
