Any differences in flow, as related to the geometry of the air bridge( cylindrical v/s elliptical) would most likely be realized on a flow bench, as opposed to SOTP.

So the only reason they use a cylindrical airbridges on boosted applications is because it can hold boost, unlike the the plastic elliptical airbridges that spilt at the seams under boost and not just to increase more air in the airbridge. is this correct??

Yep, the factory ones are not made for boost.

Fluid dynamics says no. If you want to maximize flow around a bend, you have to increase cross sectional area within the bend to allow it to flow as well as what the straight tube is capable of.
In other words, a straight pc. of tube bent into an elbow presents a restriction.

Yes. I'm at 600rwhp on the stock air bridge. I will eventually pick up a carbon fiber one, but only for looks.

So a TB to IC pipe like this http://www.dragtimes.com/images/6432...t-Corvette.jpg won't add any performance gains over a Vararam power duct, if it were going from the TB to Vararam on an NA setup?
