i am looking for a good size intercooler piping at work we have a 3in. aluminum tube with an inner diameter of 2.5in. could i use this or would it hurt my performance...

I use 2.5" piping on my setup. I believe the standard drag kits come with 2.25". I recommend 2.5". What are your hp goals?

Most intercoolers have 2.5 OD openings. I ordered 2.5" OD piping to do my home made piping. I don't know about the 3" thing. It would work, but I've seen posts here that say a 3" charge pipe would slow down your spool time a little bit after shifting by a few hundredths of a second. I don't see a big problem with using 3" myself. Maybe somebody else will throw in their $.02 for ya.

yeah i think u are prolly correct with the lag.. i will most likely just have some piping made for me or buy one from somewhere is there a place that sells mandrel bent intercooler piping?

Check out this site. Has part numbers for mandrel bent pipe and where to get the pieces from.

Also has some round about instructions on where to cut the pieces.

The 1/4" walls on your alu pipe are super excessive. I'de just buy 3 16g steel mandrel Js for like 60 bucks and be done with it.

well here is the reason i mentioned that size pipe...i work at a factory that makes parts that use that size piping...i can make my piping out of that for free..and so my question was just if it would be beneficial. if i had a choice anyways i would venture to say that aluminum would be the smartest metal to use...lighter and disperses heat better

what are your HP goals?

i am trying focus on the 300hp range and try to get that as low in the powerband as i can i dont want to have to rev to 9k to get 300hp ya know what i mean..i guess my main goal is to eventually hit 11s when the susp.is setup pretty nice...the engine will be a 2.0L lsvtec with stock GSR head and forged internals rebuilt like its brand ****** new. but yeah basically i wanna get some very low spool times and prolly max out at 300hp. help is very needed i know about turbos and stuff but i dont know what makes a GOOD turbo setup other than quality products if that makes any sense.

2.5" will be perfect for you...

any other suggestions for my hopes of low spool? how small of a turbo would you recommend?

dunkd

if ur looking for low spool use as less intercooler piping as possible and a intercooler that isnt very long... also a 2.25" turbo to intercooler pipe would help

dornon13

so are u saying 2.25 turbo to intercooler and 2.5 from intercooler to intake? that sucks about the intercooler they look so cool lol
