Why turbo normalizer?

In addition, mountain flying is less dangerous. Ground speeds are still
higher, and the prop can't convert the horsepower to quite as much thrust
as it would at sea-level. But it's not nearly as much a reduction as I'd
get without the turbocharger. Acceleration, even at max gross, is good as
is the climb rate (handy when you are surrounded by high terrain ).


Actually a constant speed prop converts HP into thrust about the same at all
(reasonable) altitudes. That is one of the great advantages of a CS prop.

Really? I just assumed that with air density lower, the prop (CS or
otherwise) had less air available to move, and thus could not produce
sea-level thrust.

I guess in that case, my longer take-off runs are solely due to the higher
true speed required. Still, that's a significant effect. I just don't want
anyone thinking that a turbocharger makes high-altitude takeoffs just like
sea-level.

The CS prop simply changes its angle of attack in response to the lower
density..

Some of them.

In the Bonanza conversions, you would need a new prop or else your engine is
placarded to limit MP.
