I thought I would post this file I have been working on. The housing shape was made by points and a line created in Unigraphics using the epichloidal formulas. It looks as if there is an offset from that formula to the real housing dimensions. I have not had a chance to do many checks so this is extremely rough. Also the corners that are shown are the corners of the irons. I came up with the port shapes using rubbings. Like I said its rough but I will hopefully be working on them as I have time. I figured if I got something started maybe the forum could help pull a whole setup of stock port drawings and also street, race, bridge, j ports that could be developed from the drawings. I believe another good step would be to create the rotor profile at different angles so that the corner and side seal sweeps could be added for making the ports. Let me know what you think.
