I liked your comments very much. Im still quite new with rotary engine
concepts, so my observations might be helpful here.
1. It would help a lot to see pictures of the side and p-port layout as
early as possible in the discussion here, then differentiate between
their advantages/disadvantages.
2. One concept that might help your "air pump" analogy is that it takes
energy (pressure) to overcome turbulence caused by bends, ridges,
restrictions, etc, in the air path. An efficient motor is an easy
breathing motor.
3. Explain that the peak torque generally falls where air flow
(abdiabatic efficiency) peaks.
4. One thing was not clear to me- why we need to tune these motors for
peak HP (8000+ rpm) when most of us never exceed 7000 rpm in real life
situations, and mostly stay between 5-6K. Why is the 4-port
disadvantaged? It is already optimized/tuned for 6-7K, and unless I
misread the situation, a bit easier to fabricate intakes for.
5. Ive read through your web pages several times and am always
impressed there; I have seen many references to p-porting there, but not
found anything listed there on how to achieve it (as in general
instructions). I'd be completely lost if it were not for some of the
pictures attached to several of the e-mails. Im still not completely
clear what is involved, other than a tube needs to be welded/glued into
a hole bored in the engine. I assume the old side ports need to be
filled? It would help to see concise instructions, sizes, etc, ready
to follow like the dumbass I am. I love theory, but frankly, I dont
want to screw something expensive up along the way.
6. FWIW, I really like your schertz beam layout for a motor mount- far
better than Crooks block spacer imho. Id very much like to see detailed
drawings for the beam and related oil pan alterations posted in the
engine area.
7. Im very interested in your turbo compounding experiment- how's it
comming? Havn't read much about it lately...

Thanks for the suggestions on the web site. I am always
updating it on almost a daily basis. I will add drawings on
the Schertz beam.
Have you seen this part of the web site Mike? Lots of pictures on
this subject.

The turbo compound project is not coming along as fast as I like
as my wife has me working on a major redecoration our house.
I am also a little short of money as I spent $7000 so far on
the TC and I am waiting a bit until my bank account has some
money in it from SS :)
I am also working with Peter Garrison who writes a monthly column
for Flying magazine. Peter is writing a Technicalities column on
turbo compounding. I can hardly wait to read it :)
