That's what I'm think too... As soon as the reeds close it's because the piston is pressurizing the case above atmospheric psi. At that very point the air is no longer being drawn in, and pressure rises sharply until the transfers open and gasses excape into the combustion chamber.
Now that moment after the transfers open while the piston is still traveling downwards the question is can that case actually depressurize fast enough that any pulling force (if the timing of it is even there to match up) in the exhaust could bring the crankcase psi lower than atmospheric psi in that fraction of an 80th of a second before the piston meets bdc and starts flying up again...
Somehow I'm not seeing it working well enough for that effect to be noticed or even existant... I understand where the train of thought is but in that small moment of time and all that turbulence you'd have to have impeccable timing to pull anything off... I really wish he had some kind of animation that could describe this wave that is capable of pulling g the already pressurized expanding exhaust gasses so strongly is can "pull" air though a carburetor on the complete other side of the motor, and it needs to be significant enough too so that it can produce a venturi effect.
It's starting to sound like a boost bottle, except instead of excess pressure at the intake it's a lack of pressure in the exhaust, both need to be extreme enough to work properly and even then the tolerances are so tight that unless you've got a lot of time to tinker you won't be able to get good results...
My method at more power: bigger motor...
