Air bridge flow testing
I've done some digging around and didn't really find anything, so I figured I'd ask.
Has there been any real world testing of air bridges to determine if one really flows more than another? It appears that some of the aftermarket air bridges oval out and flatten out (some more than others), and it's made me wonder if that will have an affect on airflow.

There is a post by Wango Tango where he flow tested a Halltech air bridge against the stocker, and the stocker flowed more.
I think it's safe to say that if you can eliminate the air bridge altogether, like the Honker, or at least keep it large/straight enough that the air doesn't have to change directions too often, then you'd make optimum power.
I wonder what, if any, benefits there are to aftermarket air bridges on modified engines?

better yet; how about testing if the stock air bridge is truly restrictive or not?
If on a stock (or mostly stock) engine, if it isn't... then it's a moot point as to when aftermarket one flows better (again; I'm taking about stock motors).

I think even if an aftermarket AB did flow better than the stock unit, for an average of $300 for a part that most likely costs 20 bucks to make - I would hope it would flow WAAAAYYYY better!
On a bone stock motor you would be very lucky to feel a differance.

And that was my thought. If a stock motor doesn't pull enough through the factory bridge to where it becomes restrictive... they placing a proven - better flowing - aftermarket airbridge gains nothing.
On highly modified engines... I could see where this might matter.
