I cannot for the life of me (and an
engineering degree) figure out why a turbo normalizer would be any
easier on an engine than a regular turbo. [...]
Running an engine at 30MP when outside is 20" is just as much
pressure difference as running at 40MP when outside is 30".

I don't do turbo (I like to fly low anyway) but my understanding from
ground school is that it is not the pressure -difference- that makes the
difference. It is the pressure for which the engine was designed.

A turbo normalizer merely makes up the difference between where you are
(high) and sea level, so the engine can develop as much horsepower at
altitude as it could at sea level. The engine was =designed= for that
much horsepower, so all is well.

A turbo supercharger pumps more air into the engine than even sea level
pressure would give it, allowing more fuel to be burned, and more power
to be generated, than the engine was originally designed for. This is
hard on the engine.

Or something like that.
