Why would it be an advantage to increase velocity? In my understanding there will be a sacrifice i.e. the vacuum in the runner isolated may be deeper. According to Mr Bernoulli´s formula: Total pressure (constant) = dynamic pressure (velocity) + static pressure. If the dynamic pressure is increased it will mean less static pressure (deeper vacuum) in the runner according to the famous formula?

Same principle with a wing foil or more familiar as in a carburetor were the venturi effect creates the vacuum that sucks the fuel out of the fuel bowl.

Is it an advantage that the static pressure in the runner is lowered as a result of the increased velocity?

Perhaps it should create a better filling with the increased velocity but at the same time the relative pressure is lowered.....

I know more factors affects a reciprocating engine and that power output vs torque is a consideration. I am asking these questions to learn from the gurus
