Intercooler Piping Size

[vaccine]

about to fab up my own intercooler piping.

what diameter cold side are most people running for around 3-400kw atw?

not sure if i should run 2.5" or 2.75" ???

[T04GTR]

the norm is 3" but some say it shouldnt be bigger than the throttle body butterfly. asuming its not a gtr?

[Travis Trayhern]

lol 3-400kw you should be looking at 3" minimum

[s13_Skyline_inside]

id go same size as throttle body/ inlet to plenum if its a gtr and same size as the turbo outlet on the hot side

[Adriano]

3-400kw is a bit vague, which one is it? Cubes has over 300rwkw with 2inch intercooler piping, although its obviously not recomended

[Yeedogga]

Big pipes are way prettier though aren't they Adro?

yeh, its going on a subaru H6 3ltr motor. twin turbo config on 10psi should will put out around 280atw's.

boost will obviouslty go up at a later stage. curous what you boyz run, as most of you make decent power.

something not always done in the subaru's. the throttle body is 2.75" or 3".

aim is for around 350 at all 4 wheels in my outback.
