I see your point
I understand exactly what your saying. Which is why gains are minimal at best. I understand the concept of what your saying, but reallistically i can't afford dyno time really, at least i don't think. I'm relatively new to the world of the tuner. Well not really, but as far as being hands on about it, I am. I don't know how expensive it is, or track time or anything. I don't understand it really, or where to go to check it out and everything.
The principle is as I stated, and it does work to a minimal extent. The valves are not always closed or always open. When they are open and air is being pulled in, there is a vaccuum. That is what causes the majority of the air movement. Which is why if it was at the air intake, it would theoretically work better. There is not as much stopping it as you think there is. I know you prolly know the inside better than I do. But air just doesn't stop at an intersection. It is AERODYNAMIC and will split around things. So until it hits a dead end it is primarily swirling. Granted that If the valves are closed when the air comes in, then it is rather pointless all together, since the only air swirling or movement comes from the vaccuum created in the cylinders. Theoretically to a tuner it does not work. And in reallity for the most part does not work.
But what I am telling you is that quantitatively in a lab where things are measure, there is a difference. I'm not telling you it is a big difference, but i'm saying there is one. If you do not trust this, then pull an engine, hook up it up and test it. You will see that i am not lying.
You go buy one and throw it on the dyno and tell me what happens if you want dyno proof so bad. I'm just telling you, I did this in a PHYSICS lab.
And I'm not being a dick, but really don't negate what you don't know, until you prove it yourself. You say you want dyno proof, then i say I want dyno proof it doesn't work. I know it doesn't work worth crap, but I know it still works.
