BTW the six port intake manifold flanges are done and I will pick
them up in an hour or so. I will bring at least one to OSH
for show and tell.

I'm interested in one of those intake flanges, is Tracy going to
be selling them?

Yep! They look great. Will take a picture and upload it later when
Robin gets home with the camera.

Also, on the subject of direct-drive rotary, I don't think it's
possible to run the Mazda at 3000 RPM direct and get sufficient
torque and power, maybe a severly handicapped three-rotor - I
think Terf was doing something along those lines?  I suppose
engine life would be much increased, like really astronomical TBOs?

You need to pump it up at that RPM with a small turbo.

There was a related discussion awhile back on your list, and I got
the impression if you were designing a new rotary engine
specifically for 2500-3000 RPM operation, it would be larger in
diameter - larger rotors, larger charge volume etc.

Absolutely. There is no replacement for displacement.

(except for turbo chargers :-))
