Now, a few years ago I bought a fairly expensive tool to balance my EDFs that uses a kind of strobe light and pressure sensors. I haven't gotten around to trying that out yet either.
What I can say for certain is that most of the volume increase you guys are experiencing when over-volting or upgrading motors is only indirectly a result of the higher rpm. It's directly a result of those flywheels being ever so slightly out of balance. It should sound smooth like a jet engine, not like a buzz-saw the way it does in Coop's latest videos. More then that though, I would expect a modest increase in performance both in terms of top dart speed and in post-shot flywheel rpm recovery time.
Please, someone do this and document it so I don't have to. Pretty please.
