The "nail through the hose" would have an effect on the velocity... not the volume. Bernoulli's equation... velocity must increase, but pressure decreases.
Actually I agree with you that the overall volume of air is determined by the size of the "pump"... the cylinder displacement. In my experience, increasing the flow velocity (through laminar flow V-Stacks) improves throttle response due to an increase in VE (volumetric efficency). Removing an restriction like the secondary throttle rod enables a more laminar (smooth) flow of air to pass through the throttle bodies.
If we change the equation to a 2 stage pump (supercharger), we now have twice the volume of air being moved (at 14psi boost), at greater velocity... which would have to equate to a relatively greater pressure drop due to any disturbance. Hence my thinking that throttle response is improved even more on a supercharged R3 by removing the secondary rod.
Some guys like golf... I love discussing these things!
