you have to remember, if this guy is working with NA applications, it's a lot different. . .
FI is forcing air in, you don't even really have to change headers out on an FI s/c since the flow is that much the better, so I think this dude's theory may stand on certain NA app's, but as far as tc, the wider the better since it RUNS on exhaust gases velocity exiting in order to turn the turbine to pump the air in. . ., it'll exit faster if it's BIGGER. OF course headers come with most tc app's, but I'm sure DemonSVT or someone else mentioned you really don't need headers with a sc. . .
just my .02, I may be wrong, everybody has their theories, hell we could banter about this for 200+ posts. . .
