Now George if you are over 70 I for give you. That is the first thing
that goes.

George,
I think you missed one point, my single rotor is based on 12A parts. I
extrapolated to 13B you are looking at around 150hp at 7500RPM.

Thanks Richard!
Ah, 150 hp that's better. I was getting worried my  single development
wasn't going to achieve a desirable outcome, you have reassured me that I
will attain sufficient hp for the application. It would be nice to achieve
150 hp but not expected - 115 to 125 hp would do me fine.

I am using some 12 A parts myself (end housings). There are early 13B rotor
housings available to suit, without the seal groove - like the RX8 housings.

However if I had my time again, and had I thought of it, I might try to make
those thin walled chrome molley (Powersport development) end housings.
However putting in seal grooves, would be a serious other issue.

My apologies for my confusion.
