Paul,

Wonder if you have dimension / drawing of 13B Rotor, I want to price
it out for Si-Al Alloy to reduce weight. Thought it might benefit
all those who want a lighter weight engine.

Jeff has the dwgs. He has been working on a titanium version.

What is the working temperature of Si Al?

The rotors run 500 F in some places.

I understand that melting point is over 500C. I notice that they are used
to cast pistons used in combustion engines.

Henry


Worth a try. CW did some work on ally rotors.

You will need some steel inserts to hold the apex seals.
