That gif file(s) is awesome. Now I know what MilesB has been talking about with port scavenging etc.
And how important it is to get the waves to match up.
Thing is, this is very specific isn't it. Like specific RPM (piston timing), very specific cam (when the ports open/close).
So you'd really have to define an RPM band that you want it to be in the sweet spot (intake/exhaust tuned for) then build it ALL to be at that point.
How wide would the RPM band be for the sweet spot? Are we talking 100/200 rpm and a bell curve away from it?
