Hi Dave,

OK, one revolution of the e-shaft is 1/3 revolution of the rotors. So
each rotor has had one intake event.  Each face has a calculated
displacement of about 650 cc.  Two X 650 cc = 1.3L.  If you can explain
why it's 2.6L, maybe I can send Paul an apology.  Or are you just
trying to get my goat? :)

I'm not trying to create a big discussion on the displacement of the
rotary, I just want to understand where that 2.6L per revolution number
is comming from.  I haven't been able to see it.  I think Paul gets it
from comparing to a piston engine, and I agree that the 13B compares
closest to a 2.6L 4 cycle 4 cylinder engine.

Monty, Glad to have you and you know you will always be welcome here.
However, you are wrong and 'he' is right about the displacement of the 13B.
It is 2.6L or 159.6 cubic inches to be more exact.
 That is the volume of intake on one revolution of the e-shaft.
 But I think you knew that, you were just trying to get his goat. ;-)
