Is a 4" intake pipe overkill What do you think the efficiency if from a 3" to a 4".
I know the tb is closer to 3" but the easier it can take it...
I have twins running into two 2.5" inlets on the inter cooler then a outlet of undetermined size. Then straight to the TB.

my TB is 4" od which hooks up nicely to a 4" tube.
overkill, maybe if your trying to only make 500rwhp, but if your shooting for 1k rwhp, it might help some
my turbo has a 3" outlet, here i run that size tubing to my IC, where i made it have a 4" outlet, then that size tubing to the TB (no maf).

i agree with the tb thing, but your intake is feeding your turbos. Then it is pushing past the tb. I would think what ever size the inlet is on the turbo is should be good, because you are not restricting the turbo. My inlet on my turbo is 5 inches, but i just put a 5 inch arifilter on it and called it a day.
