i have a b16t set up right now and im runing the hot side with 2.5 plumbing and the same on the cold side, im making about 300 with this set up and im wondering if its going to hurt at all to run 2inch on the hot side and 2.5 on the cold side when i turn the boost up to make my 400 whp????

thanxs

 

it would be best to have 2.5" all around...

 

would it increase my spool up time and still make decent hp if i was to go to 2in.??
on the hot side...

 

boost would come on slightly later because you have to fill more volume inside the piping, but if you dont get larger than a 2" you're going to be restricted if you plan to make more power....what is your setup?

 

built b16t, riht now 300whp soon to come 400whp....thanxs

 

well what turbo are you using?

 

why would you change the IC piping in the first place? if you already have 2.5" i would just leave it. if spool time is what you are woried about, i dont think it would make that much of a difference. what IC and turbo are you using?

i heard it would increase spool up time, im also using a spearco ic and a t3/t04e 57 trim turbo..
