What are the design critia for bell mouths. I assume any radius helps, but there seems to be a wide range of shapes out there from  little circular radius bellmouths like these to larger more
gradual and epilliptical ones. When I made a set for Brian Trubee, I just took the dimensions he wanted and modified from circular to elliptical because it seemed more logical from an airflow
perspective. It was a fun project, but way too much work on a little 7X chinese lathe CNC conversion. Made heaps of swarf :)

I would guess this topic much have been explored at great depth by the racing community. May be Archie has a definative word for us?

Those are beautiful Mark. How much money do you charge? 

Do they fit 2 inch OD .065 wall tubing?

How does one fasten them to the tube?
