"Airflow and How it Makes Ponies" Theory, Someone help me out. Options

Alright guys. I've been looking into intake induction for a while now. I've probably changed out my intake design probably 5 times already just to try to get better gains. I was thinking about getting cold-air intake next since I have a short-ram intake. BUT, as I was thinking, something hit me and it got me questioning really good. As people keep talking about intake, they talk about airflow and how it gives more horsepower by more airflow into the chamber. And ofcourse, more air means more fuel needed. But something else hit me hard. I've changed my intake system a couple times already and all of them felt different in responce. Not majorly but you can tell (it's ur car, you would know). Intake isn't about how much air is going in. Now that I think of it, it's about vacuum! It's not air getting pushed in, it's air getting pulled in. So I questioned to myself, how do I increase the vacuum velocity so that I can get some better gain than what I have now. Well I did some quick research. Apparently, it's all physics. Something that I'm not good at. But my uncle majored in Quantum Physics in college. So I asked him, "Hey, do you know anything about vacuum and velocity for airflow?" And he said, "Yeah. What for?" I said, "I'm trying to figure out how to make air sucked in faster into the my engine without having to spend a big butchet." And he said, "The smaller the pipe, the more vacuum you'll create." And I paused. I said to myself, wait a minute, most of the time, bigger is better when it comes to cars. Like for instance, the bigger the tubing, the more space it would have to channel air to be vacuumed. But it would not create faster vacuum or would it? Not sure but I decided to do more research. And it turns out, that constriction (snake swirl) type tubing actually helps vacuum velocity increase. Not only that but if you have a constriction figure at the both ends or in the middle of a tube, velocity speed increases and also less pressure. I'm stealing these methods from G. B. Venturi who died 1822 as a Italian physicist. http://biyografi.info/kelime/venturi So I figured, how come no ones ever really thought about this? This would actually evolutionize intake tubing design. What do you guys think? Am I onto something?

tornado, the $60 "turbo" is what you basically came up with. It sticks into your intake tube and swirls the air around. Creating more velocity.

The truth really is that even if you have uber velocity, your intake manifold will most likely not notice the difference. you did good with your howmework tho and i like your thinking. I think if your gonna do this velocity testing and stuff you should have a dyno to back your results up. No intake variation will give you much noticable difference while your driving. But if you could get some dyno numbers in there many more people will accept your ideas!

True. I was thinking about doing dyno tests too. But first things first, I'm definately starting this project just to make sure. But the tornado, no. LoL. That thing isn't what I had in mind. Becuz the fact that it has a star like figurine throughout the whole diameter of the pipe, it'll actually slow down vacuum. But I'll figure it out sooner or later. Right now I'm most likely gonna save up some money to create my own intake designs and different variations and then dyno testing them. Thanks for the comment bro.
