not too long a goa there was a show about F1 on discovery, and they 
showed how a great deal of efford and simultion was put into an air bow
design that would give an even distribution of air to the cylinders and 
not just ram it into those furthest back

and I've heard that on some rallycross cars with right manifold
design they can use as much as ½ a bar more boost before getting
it problems with detonation. I assume, without knowing, that' got
to do with getting an even mixture on all cylinders,
