Where is it the rear PCV flows into? is it into the air box? The front seems simple but i'm wondering whether to have a single catch can where both PCV's flow into it and have one exit pipe maybe paired with an induction system to try and remove some of the plastic rubbish they fill the engine bay with

Whats the baffles like in that kit as well?

The two PCV systems have to be separate from one another. The rear one goes straight into the intake manifold and the front one goes into the air intake before the turbo. The rear one will have full boost pressure at times so you need a system that can handle the pressure without blowing up :P

I got an aftermarket air intake to get rid of the stock airbox and all that plastic crap. It frees up a lot of space and makes it easier to fit a catch can setup on the back of the firewall.

I see, makes sense. Do you know how much boost pressure runs through the rear pcv?

[notrix]

All of it? :P I'm not entirely sure so don't take my word for it.. but since the rear PCV is directly connected to the intake manifold I would assume so. In the attached picture you see how the rear PCB (B) is connected.

Have been running a setup like this for about 3 years now. Connection at intake manifold caped off, both lines running into a single can then back into intake before turbo. No issues so far.

Yea I understand how it all works, just looks like a ball ache to get to the manifold attachment. Has there been any difference to the power of your car after doing that cyclone?

The line as said is under whatever pressure the turbo is making at the time so up to around 1 bar.

Yah it sucks getting that cap on. No change to how the car feels.

How did you connect the hose for the can to the rear PCV on the valve cover? Did you cut the the OEM tube and joined it to a silicone hose? Pics would be much appreciated if you have any

The forge catch can system doesn't seem to deal with the rear pcv yet it costs so much

Yeah.. I would gladly pay that price for a plug and play kit if it would take care of both the front and the rear PCV. It's a shame no one makes a kit for these cars since it's crucial to take care of the carbon buildup in the intake if you want these engines to last.

Modified a cap (it is the same type used to block the intake manifold side) by drilling out the end and used JB weld epoxy to attach a fitting to it. To be honest I believe a duel can setup is the best solution I was just being a tightwad.

[Sean8098]

I will build my own system then, there shouldn't be a pressure issue as your dual can system uses mesh to filter the air, which would get damaged under high pressure. I'll give it a shot and we'll see what results we get

That's clever.. never thought of that I'll try and get hold of those caps!
