sledcrusher- anything can be fixed with enough $$

Kas83- It's been along time since I did physics or any geometry, but is there a real difference in square versus round at that point? The air should be flowing smooth and straight after passing through the intercooler, so as long as the square has the same volume or more then a round pipe, which in this specific case would be as long as the square intake can pass as much volume as the intercooler tubes can pass, does the shape really matter? Obviously the surface finish matters. Are there any flow bench numbers on square versus round same volume? Now I'm really curious. I mean, say what you want about Bank$, he does know airflow.

 

I can't really say that round is better per say, but I've been looking at it as to how the air exits the intake horn. I feel that the round tubing will make a smoother transition. Can't put it into words right now. Haha, now you've got me thinking on this too.

Banks does know his stuff, I just feel that there is more to be had.
