I am trying to get a general idea of what size tube people are using for
their intake manifolds. I will uses these numbers for a starting point
and modify them for my design using tuning equations and such.  

1. Runner diameter 
2. Runner length 
3. Plenum diameter
4. Plenum length
5. Location of fuel injector

Speaking of tuning equations I am looking for the tuning equations of
rotary engines. Could someone point me to a location that has them or
send them to me. 

Thank You 
Alex Madsen
