Paul,

I've been receiving the newsletter for a short time now, and have found it quite
informative.  I've also been going to many of the sites you have links to and finding
a wealth of information about the Mazda rotaries.  I'm planning on purchasing the
Twinstarr gyroplane kit and using a 13B as the powerplant, instead of the recommended
Lycoming O-320.  I will be moving to Colorado and therefore will want to be
turbocharging the engine in order receive near sea-level power up to around 15,000
feet density altitude.

My question is - do you know of anyone who has successfully matched a turbocharger
and control to normalize the 13B for a maximum 160 - 170 hp up to a critical altitude
of 15,000 feet DA?

(In "Turbochargers", by Hugh MacInnes, the author indicates that aneroid-operated
waste gates are most often used for turbocharger control for what I'm thinking of
doing.  Do you have any experience with these?)

Inquisitive in Phoenix,
Scott Speirer

I know of several that have flown turbo charger but so far nobody has uploaded
the high altitude performance. What you suggest however looks quite feasible.
Hugh MacInnnes's book is the best there is IMHO. You might also buy Corky Bell's
book called Maximum Boost.
