Yeah normally I would agree. That big nozzle should help airflow. But the problem is the S4 manifold shifts the turbo inlet downward quite a bit, so there is possible interference with the a/c and/or PS. Fortunately I have depowered the PS so that is no longer an issue. Just the a/c belt tensioner will be there which is a lot smaller and further toward the front of the engine.
And before the whole a/c debate thing starts, no I am not ditching the a/c

I think he was talking about the inlet velocity of air. As you increase the diameter of the path the air travels, the velocity slows down as well. Vice-versa happens when you make the inlet smaller. Yay physics/fluid dynamics! However, the difference will be barely measureable so I wouldn't worry about it...

well no actually I need to get down to 3" eventually for the CAI so I can incorporate both transitions into one.
I think the flow regime will be fine and will not amount to more than a minor loss by my calcs. I am more concerned about the clearance.
EDIT: Sorry I was traveling on business and did not have full access where I could see the picture above. That helps, thanks. After looking at yours, and looking more at the BEGI S4 system picts, I think it would fit with the 4" inlet if I use a 90 deg bend.
