Trust me I understand the concept. You squeeze more air in a given volume, now move it along at a fixed velocity. You're flowing more air but the velocity is constant.
But pressure and velocity arent constant--at all-- so the formulas break down. I'm trying to explain that it's not as simple as plugging it into a formula. Those formulas also assume a laminar flow which is absolutely not the case.
I also think it's helpful to remember...
1. Power production is a result of burn rate of air/fuel (mass flow)
2. Pressure is a result of flow restriction
Anyway, I still understand the need to have a certain amount of flow velocity. I can see how it's helpful for increasing volumetric efficiency.
