Air Induction Systems, Voodoo, and simple test

or can you gain more by making it a similar design, but smaller so you have more velocity VS larger bore and slower velocity

why is everybody making CAI now?

If you read the original post all the way through I think you would see that why was my original question.

[blunttech]

eric lukas was the original bathrobe clad god of the CAI. you guys are mere commoners

No... I think Steve Dinan beat him to it. (now there's a guy there is no point in arguing with)

I did. I think you should go threw with your plans. also I noticed when I did the M30 AFM it made my car run very lean untill I did the injectors to match, doesn't that mean it flows better than the stock AFM? but I do see how a bigger door could mean a bigger restriction.

You're missing it...

It's not a question of restriction but velocity...

you mean this way?

[DCColegrove]

you mean this way?

Yes kind of... It's a little bit more complicated than that.

If the induction uniformly draws more air through a larger volume it wouldn't be the case.

EDIT: I don't know if I can make sense of it to you without illustration...

like a velocity stack or a venturi effect to keep the air speed up and on as straight a path as possible.

i think i get your drift. i messed around with something similar, waaaay back in the mid 90's with CIS-E on VW's

Yes on the V stack to align the air initially entering the induction.

The big trick is to keep the flow accelerating in a uniform fashion from the inlet to the combustion chamber...And ultimately to the tailpipe.

The optimum is a straight line (but not a smooth bore) but not really practical under the hood.

No...

I was pretty much this way long before they all started driving...

Hell...Before some of them were born.

Why don't you chill out a little.
