I agree. As one pulse travels through the collector it's inertia causes a low
pressure pulse in the other pipe which of course increases the exhaust flow out
of the other rotor 180 degrees out of phase.

Russell Kent interjected:

You mean 60 degrees out of phase.  :-)

Paul Lamar responded:

One pulse per 360 degrees of e-shaft rotation from each rotor.
The rotors are located on the e-shaft 180 degrees apart.
There fore the pulses are 180 degrees out of phase.

Agreed.  You were talking about rotors, so I made the presumption that you were talking
about rotor phase, not e-shaft phase.  My bad, apparently.
