intercooler piping to stock sidemount

[mathewdylang]

Ok this question is gonna seem weird probably but i can get custom bent pipe at a shop in town so i was wondering what would happen if i ran 2in pipe which is what the jpipe is to the factory smic and then ran 3in after because i have a MAF off a 96 firebird lt1. than reduce it at the TP? my MAF was bad when i bought the car and i know the GM is an upgrade i bought a translator from dsm link. so any thoughts on 2in before and 3in after?

read some of this thread, there is good information.

"As far as lag goes, it will not make a noticeable difference what size piping you use. I'm running 2.75" piping with my large FMIC and little 14b, spools as quick or possibly even quicker than the 1G piping I was using and stock side mount. The extra volume of the larger piping just means less flow restriction. Not that a half inch piping diameter difference makes any more than hair-splitting differences at the low airflow a 14b or even 16g offers."

well the stock intercooler pipe the hoses, are they 2in or are they larger? i cant find anything via search on here because it always pulls up discussions that its been mentioned once and never again so impossible to find in 13 pages. if i ran 2.5in and just an expander to the maf wouldnt it cause turbulance in the air? idk im still learning turbos . thanks for the help.

i have a 2.5in hard upic pipe from injen, running to a 3 in gm maf and back down right before the throttle body and dont seem to have any issues!! I love the GM maf!!

thanks . i guess ill just go 2.5 the whole way to the maf... i hope this works out... boost leak is a killer when a honda kid comes up next to you and actually gets you on a jump... until you pass him...
