hooking up a forge 004

[Sick_Boy]

ok i just received my 004 and i just want to make sure im going to hook it up right. so since its just a dump valve should i hook it up to the spot marked as 1? or 2? and im all stock right now but gunna be getting a ecu flash soon so is it ok to leave the yellow spring in set for 15-23psi or do i need to use the next one down? and is it ok to run a dump valve im not going to mess somthing up by leaving something unhooked am i? thanks

hose 1 is off the intercooler line and 2 looks like its going to the air line doing into the turbo. im pretty sure it goes to 1 but just want to make sure

You should be running a Diverter valve not a BOV unless you are BT and have a MAF-less file

Although I have a B6. I ran a yellow spring for a long time and I'm stock, I tried to run the green spring, but on cold start ups the car would shudder real bad cause the valve was opening under the higher ideal.

But just recently I have been running the green spring after bypassing my n249 valve, cause the car seems not to like the yellow one anymore.

Do you mean the forge 007? the 004 is a BOV

it goes into the lower intercooler (from turbo outlet to cross pipe)

the billet plug goes in the recirc hose (leads up to airbox)

the 004 will be fine, it closes at idle so its works just fine

For those who say run a dv, the 004 will work fine. Ive had the 004 on my 98 for almost a year now with no ill affects.

I'm running the 004 and turns out I know NOTHING about it, lol......it works great

if the 004 is closed at idle then you should be fine
