I get what your saying. There’s only so much air that will drawn as it’s being sucked by the pistons movement. . . . .
it really isn't that simple; the goal is to get as much air/fuel mix into the cylinder as possible, and for practical purposes we will never get "100%" due to the pressure drop through the intake
If you do the calcs, there is no loss of flow that is above negligible..... .... the oem TB will flow up to 900 cfm...…. I have not run the calcs on the mustang, but, the TB well exceeds the capacity of the engine, and the bends, even if you calc in the maximum possible restriction it does not reduce the flow by more than 1% and the system by design exceeds the engine capacity by 15%-20%..... so even if you loose 5% of the CFM flow because of all these restrictions.....you are still capable of flowing a full 10% more than the engine can injest.
those calculations are meaningless if they do not include pressure drop through the system; if you look up the test standard for those flow rates, they will always include a pressure drop; and the whole point is to reduce the pressure drop for a given flow rate
This would cause a super amount of turbulence. I’ve built piping systems for a living. . . . .
yeah the pipe thing is really a different situation all together, I think the goal there is to increase the velocity coming out of the nozzle so it will spray farther; not to reduce the pressure differential through the system
this oversimplification of flow rates can easily lead you to the wrong conclusion . . . but still, for practical purposes, my conclusion is "don't expect much and you won't be disappointed, do this stuff for the fun of it, not because you are expecting some specific gain"
