i searched for a long time and got mixed answers about piping size. I am running a 60-1 with a 2.5" outlet to intercooler and was wondering if the 3" intercooler to TB was too big. I appreciate all opinions.

ok. but i still don't know what to go with. its 50/50. if i go 3" there will be more lag and less pressure drop and if i go 2.5" it will be hotter and more of a pressure drop. right? I don't know, i have read so much info in the past hour and a half and its late. somebody please help me out

 

I have the setup your talking about but I am running a T3/T67 HO turbo and it doesnt seem to be any difference in running that compaired to a 2 1/2 on both hot and cold side.

 

The Lag is neglible. The difference, if i still remember correctly from the math, is .12-.15 seconds per foot, can you feel that? Im running 2.5 and 3 inch on my setup and im only going for 300whp from a SC34. I feel the cooler temperatures and the less pressure drop makes a difference for me.

 

all thats sounds good to me! anybody else use 3" piping on there setup?
