The talks circle back to the piston sucking fuel charge into the cylinder so here is a mind twister to kick around. If the piston is responsible for filling the cylinder what if we increase the size of the intake valve or have 2 or 4 valves per cylinder? If the bore diameter is 4 inch what if the the intake valve was 5 inch in diameter?

If the intake valve was not restricting flow or creating a pressure differential on each side of the valve when opened would the cylinder still get filled if the is no SUCTION? ( bore is 4 " and intake valve is 5 " and very high ramp angle)
