Great in theory. I cannot help but wonder, however, if you could get more
"bang" for your effort if we instead concentrated on ensuring the
propering
ducting of the radiator(s). Never forget that the oncoming airstream has
only about 0.1 to 0.2 psi available to shove the air through the radiator.
That isn't much, and every little obstruction hurts.

I have to agree, about the exhaust augmenter. Why not make the ducts right,
and put an electric fan in behind the radiator, ala many/all front wheel
drive cars. at your speeds, the drag should be low.
