Paul,

I am a new "member" of your newsletter service and am most
intrigued with what I have gleaned thus-far from your elegant articulation of the
benefits- superiority - of the Wankel-cycle vs reciprocating
piston/crankshaft heat engine technology; additionally your discussion
of turbo-compounded engine technology has attracted my attention.

I am MOST INTERESTED in engine turbo-compounding technology and wonder
if someone in your "group" is able to supply or would be setting up
to manufacture units for the 2 and 3 rotor Mazda?

Where are you located ? I travel extensively in the US and perhaps, if
invited, could drop by your offices for a cup of coffee...

Thank You for a most interesting website and newsletter.

They are in mass production by Detroit Diesel. Look up DD15

There is a company in Colorado that offered  enough money could be
talked into
building a production turbo compound for a rotary.

I don't have the money or the time in my life to start another biz.

I am building a turbo compound 3 rotor but strictly for dyno testing to
prove the concept.

I am in Santa Paula CA.

Paul,

Thanks for your feedback to my earlier comments/inquiries (below).

I will be most interested in the results of your investigations re:
yourturbo compound integration of the DD15-Mazda rotary engine. Also Most
Interesting - your rotary-DD15 system photos - Thanks.

What is the factory’s part/assembly number for the DD15 turbo compound
unit; proper rotation for Mazda; do you have an approximate cost for
theDD15 turbo-compounding unit from Detroit Diesel?


You wrote in “*TURBO COMPOUNDING THE ROTARY*” that the ROOTS BLOWER
typeturbo compound system “
remains however as the simplest and easiest turbo
compound engine to build as all parts are off the shelf.”

For non-aviation genset applications, could ROOTS BLOWER-based
configurations be an appropriate alternate vs the DD15 platform?
Relativesizes ? Efficiencies? Costs?

And finally, for today at least, you mentioned a Colorado firm possibly
interested in production of turbo compounded rotary engine systems –
whowould these folks be and could you please provide me their contact
information?

Thank you, again, Paul; I am enjoying your newsletter immensely.

It is a series of part numbers but I lost the paper work.
Get with a DD15 dealer parts department and they can look them
up. The cost is $2500 to $3000.

The big question is will the roots blower take the heat?
I doubt it.

I forgot the name it was a spin off of Woodward Governor.
I'll have to search the inbox. Hang on.

Here it is.

Mostly vapor ware so far. At least I am building some hard ware :)

Also if you are not working with the rotary or a diesel  you are
asking for exhaust valve failure :)

Paul,

Do you have a frequently asked questions list somewhere?  Maybe you could
send it out when someone first subscribes to the list.  On the other hand, maybe this idea
has already been discussed a couple of dozen times, and it's in a frequently asked questions
list somewhere...

Not so far. Answers evolve in 15 years. New materials and parts appear.

Paul,

If Mr. F Parker is interested in manufacturing a 2 or 3 rotor he should talk to Larry Childs at Designit Proto type.

His number is 707-753-0702.
