Paul,
I just finished reading your article in Kitplanes about the
turbo compound engines and my interest was aroused as i was
given a Mazda rotary engine?with a Ross redrive, but have not
used it in a plane because of the underpowered nature of that
engine and also because it is extremely loud. Are you or someone
you know working on a turbo compound system for the Mazda
Rotary? If yes, i would be very interested in purchaseing one,
or any info you know of. Last question in the picture of you in
the last page of the article, are you wearing a" Floater" hat
made by Dorfman-Pacific?

Thanks for your time,
Ed Smedley

Nothing wrong with 250 HP but you need the right intake system.

What ratio is the Ross? The 2.85:1 is the best.
The 2.17:1 is not so much HP as it cannot rev much beyond
6000 RPM with a good prop. Besides that the prop rotates in
the wrong direction. Also a thrust bearing must be added
to early Ross PSRU's. Get back to me later on that and
I will show you how to add one.

The engine can be made quite with the right muffler.

I would not hold my breadth on a rotary turbo
compound system as that may be down the road. Especially in the
current economic situation. Things are not looking good for investment,
innovation and hard work :)

Yes on the hat :)
