deusxmachina said:Unless you're running 10's, I'd say it doesn't matter. 2.25" argues for better spool-up, 2.5" argues for more flow, but unless you have a race car, it's a toss-up and I have yet to see anyone show noticeable differences either way. For a 16g, 2.25" is easily plenty.
how big of a difference in a spool up would it make... can you give me some numbers..
300 rpm 500..???
