Turbo Lance II opinions

I found some readings that said the Turbo Lance has a fixed wastegate and
that there are other systems out there that have a manual wastegate that
allows the pilot to better control the turbo.

How much of this is really a factor and should I really care?

You could interpret a manual wastegate as something that you have more
control over or you could say that it just provides more workload :-). The
Turbo Lance wastegate is attacked to the throttle linkage and works pretty
well. The best system is a compensated automatic wastegate but that is
considerably more expensive and complex.

On cars, the waste gate is basically a variable rate spring inside a
metered valve. As the pressure increases, the valve opens...as it
decreases, the valve closes. The valve releases excessive pressure within
the turbo, thusly preventing overboost. On cars, they are simplistic. I'm
not sure how much is different between a waste gate on a car and a waste
gate on a plane.

Having said all that, I'm 100% sure I would not own a turbocharged
anything that did not have an automatic wastegate on it.

The difference is that the airplane wastegate should compensate for
different altitudes.

As should also add, I would imagine that a turbo-normalized engine has a
much more complex wastegate. That's obviously a guess on my part.

For my money, I'd care. There is a series of 6 articles on turbocharging by John
Deakin at avweb.com. Here's a link to the index of John's Pelican Perch articles:

Scan down the list to the "Those Fire-Breathing Turbos" articles.
