Does this make more power? I think it's hard to say.

Clearly BMW put many hours into the design for a reason. Was it strictly to cancel engine noise? Maybe.. Or could it have been something to do with airflow?

You definetely need to dyno your car and see what kind of results you get. And you need someone's stock box for comparison. This would be the only way to really know if there's actually an improvement.
All I can say is it performs a lot better than before this mod. My butt dyno has no printout or any fancy graphs. With or without actual HP, I enjoyed doing this mod and sharing it to the forum.

Not really. Turbulent flow is sometimes better. Turbulent flow is good for heat exchangers. When it's for heat transfer and mixing purposes, turbulent flow creates more surface area. So air flowing through an intercooler when turbulent is better but laminar flow in the engine is the best. This is what I deduced.

I only studied fluid dynamics back in college so not too sure about aerodynamics. Did I tell you guys I have a Chemical Engineering degree?

Its a good thing that you are not terrorist.
