PostSubject: intercooler piping question   Sat Mar 24, 2012 4:41 pm

ok so i am getting new couplers and intercooler piping

the outlet on my turbo is 2'', the inlet on my intercooler is 2.5''
would it be better to run a reducer at the turbo or at the intercooler? with a bov in between

here is the set up now, its 2.5'' 90 degree to another 90 degree then goes to a reducer to 2'' then to my bov

here is right off the turbo

the way i see it could be 2 ways

(turbo)[90]2''=====[90]===(bov)===90=(reducer from 2'' 2.5'')=== intercooler
or
(turbo [90] (reducer 2'' 2.5'')====[90]===(bov)==[90]===(intercooler)

sorry if i confuse anyone...
if it matters to have the 2'' stop at the turbo, or 2'' stop at the intercooler

i'm not a scientist or anything but i think the reducer into the turbo would make more sense.

honestly i think you need to simplify your piping though so you have less couplers and more actual metal pipe. you are going to have less chance of a boost leak from a coupler popping off that way imo. you're going to vinny anyway....just have him weld some shit up and then get some coating on it so it looks peachy.

1 step ahead of you chuck, but thanks for the advice
i am ordering elbows and am getting rid of 3 couplers for sure
its gonna be once piece from turbo to intercooler
i just am trying to figure out if i stay 2'' thats less pipe to buy, or go 2.5'' and buy all new stuff

i tried searching and i just found some shit that had nothing to do with my question lol

but for real, thanks

anyone else got some input, im gonna put my order in for my piping and elbows and shit on monday?

The kit that I bought for my car(ISIS) came with all 2" piping from the turboto the intercooler(hotside) and 2.5" from the intercooler to the TB(coldside). Larger tubing will give you better flow on the topend, but the smaller tubing has less volume internally to fill/pressurize so in theory that should make your turbo just a little more responsive, or less laggy. The shorter the piping run and the less internal volume, without being restrictive will make for the most efficient system. I am no engineer though so this is all just info I have learned and absorbed through lots of research. Plus my kit is basically a ripoff of a greddy and Blitz system. So I am sure that they put some R&D into there design for us already.
