Dennis, I realize there is one bit of information I don’t have handy on the Renesis.  If you have it, that would be a great help.  I need to know the opening and closing timing for the Renesis intake ports.  That factor is important because as you realize, the total distance required is from the initial opening of one intake port at To to just before closing on the second rotor.

 We know the intake port on the second rotor will open at To + 60 degs as the rotors are 60 deg different in rotation on the two rotors.  But, we also need to know when the intake port closes as the total time for the pulse to travel is roughly To + 60 deg + Closing Deg (- 10 to allow pulse to get there before the port is fully closed).  My calculations were for the old 13Bs and I have no idea if the intake port opening is the same for the Renesis, but if different then it would make a difference.

So do you happen to have the port timing for the 4 port Renesis?
