The article is pretty good on the science but who knows if they right-sized our airbox. I can't see some designer saying 'make sure we have room on the BA for an eight liter airbox'. They probably ball-parked it and made it fit. The article doesn't consider air dynamics either. Air is not a 'slug'. It behaves much like a fluid. It swirls either clockwise or ccw as it moves - that's why engine stuff is round. I tend to agree with Dingua's dyno, more air=better.
