Vacuum Lines...newb

ok so i dont understand what to do with the vacuum line setup. I just got the car not long ago, and as far as i can tell its stock except for a CAI, and aftermarket BOV. Ive been reading up on this and im confused as to what to do or how this improves the performance. Oh BTW i have a 3" catless Y with cutout. I do have a CC, 2 to be exact. Can someone answer my questions here? No smartass answers either. THANKS!

How what improves performance?... what exactly are you trying to do? If you have a BOV and a CAI, run the black hose that went to the stock airbox to your CAI, put a breather valve on your valve cover and tap into a line from the intake manifold for the signal to the BOV. That will eliminate the pink line I believe it is to the surge valve and you should be good. Look up the diagrams by NorthNJsrt or something to that effect... he has them all diagramed.

Thanks a lot. Yea I've seen a bunch of diagrams, but I was wondering what re-routing the lines actually do. When I look at the diagrams, there's no clear description on exactly what it's supposed to do. Get where I'm going?

I think you are looking at the port on the driver side of the valve cover on the side. The PCV is on the passenger side on the top.

What I get is that you should leave everything alone since you don't know what you are looking at as well as anything about a turbo car. Moving those lines around doesn't get you performance...but you would know that if you had read anything in the performance modification sticky area...

So, the PCV goes to the catch can then out of the catch can over by the throttle body to a little filter?

It should be hooked to the throttle body.

I see in your pic the PVC connected to the red catch can, then it goes out towards your throttle body and I can't see anything else because of the red blob in the pic.

Your PCV goes through the catch can and into the TB like its supposed to, you can see it in your picture. Take a close up pic in your engine of this filter your talking about.

Engine bay looks great btw!



It's 106 miles to Chicago, we got a full tank of gas, half a pack of cigarettes, it's dark, and we're wearing sunglasses......Hit it
