Default Boost control for turbonormalizing.

Howdy,

Given that there are now a few pseudo constant speed props available
for engines ~100 bhp, I was interested in looking at how a
turbonormalizer would work in engines of this range.

Has anybody here looked at the Rajay system or another of the
turbonormalizer kits? How do they regulate boost control? Is the waste
gate barometrically controlled, or is does it measure manifold pressure
or what?


-Thanks!
-Matt

Default Boost control for turbonormalizing.

Not ALL Rajay turbo installations used a manual wastegate - just the
affordable ones!

And that is NOT turbonormalizing, which aims to keep the manifold
pressure at some nominal "Sea Level" pressure regardless of altitude.

They do it with a wastegate that measures manifold pressure, and
compares it against a sealed reference standard "pill". Some
installations allow you to set the "Sea Level" manifold pressure you
want, and it handles the rest.

But as Bill noted, everything affects manifold pressure. The system
I've described, while less prone to pilot induced engine meltdowns, is
far from foolproof. Making it more foolproof costs even more money and
weight.

When Peter Garrison wanted better wanted better high altitude
performance from his original Melmoth, he weighed all the options, and
went with longer wings.

a few.

More cubes are just a better solution.
