If you boost last (as in your climb, gradually and after WOT falls below 30 in
Hg), you're compressing progressively cooler air. The higher you go, the more
boost, but the cooler the ambient air. I don't anticipate totally eliminating
the need for intercooling, but I think my scheme will very substantially reduce
it. And that is very important to me, what with all the other heat rejection
issues I will have.
Just a theory ... Jim S.

With respect to the need for intercoolers, bear in mind that it is the
adiabatic heat of compression that heats the air, so the more boost, the
more heat. whether you use the boost first,last, or in the middle doesn't
seem to matter in my mind, the heat of compression will be the same.
