Yes, the blower wooould have lost some of its power compared to sea
level,
but what I would propose is turbo normalizing, so the increased power is
of
no use at sea level. Of course, it could be used to provide a boost for
take off and such.

Now, for all of the "IF"s !!! Not that many induction systems
would
take the added pressure without modification.

But Jim. . . If the engine is just returned to sea level conditions, where
is the pressure? At your given example of 8000', the manifold pressure
would
still be less than atmospheric pressure, would it not?

I don't see what you don't see.

If there is an effective boost on the engine, the manifold pressure at WOT
will be the same at 8,000 ft as it is at sea level at WOT. An engine at
cruise at sea level will usually run a couple inches less than atmospheric
pressure. A normalized engine would run that same number at altitude, vs.
an un-normalized engine running the atmospheric pressure at that altitude
minus a couple inches pressure.

What was it we were discussing? g
