Ideally, you hook it up to a Hobbs switch that triggers it whenever you are in boost. You may need to see how much vacuum your pump can pull and add a relief if it pulls too much.

Right now, my flapper tube is literally just hanging. I don't drive the car so I'm not afraid of making a mess, but I need to do something with it. Was thinking of welding a bung onto my intake pipe right below my filter and just going that route.

Mine runs from the flapper to my filter (top mount) with a OCC midway through. Works well.
I like the idea of a bung on the intake though.

Wanted to bump this thread back to life, I am also considering the radium catch cans: http://www.radiumauto.com/Universal-Dual-Catch-Can-P189.aspx

I have the RB PCV kit, so I think I'll buy these cans with the same 6AN barbs. Anyone got any experience with these cans? Are they too restrictive for the high side VTA?

I don't think I'm ever going to understand the pcv system but the 6AN lines seems a little small though but I could be wrong. I think I read somewhere that the oem size of the pcv system is 3/4". So going 6AN would already be restricting it right? Again I could be wrong lol.

If you do go with the radium cans get the 20 oz size. And how restrictive it is depends on how much stainless steel mesh you put inside. Order the fitting sizes to match the hose size used.

@A4RingedONE8T can you make another one of those? I don't have the same strut bar, so it would need to hook on to somewhere else or have some sort of other connector.

You know I built Eric's car right? =) The CC bracket will include SS button head M6 bolts for attachment a few different ways. What are you trying to attach to?

I know you were doing some work on someone's car, the first manifold you did if I recall.

The place I have to mount my cans is just the stock areas. I'd love to mount it to the firewall but there are lines in the way. I wish there was a more stealthy spot to put them, but hanging from the brace may be my only option.

I'm going to have to order one of those brackets here pretty soon. I thought this was a custom made bracket and not for sale. Really going to make it easier mounting and plumbing everything together.

Eric's was the 4th N54 mani I built, it was just the one I used to model the billet version.

Agree the the CC's look like shit anywhere you try to fit them. Size/shape and lines into them don't make it easy for a clean install. If you remove the plastic clip/holder for the AC line there is a bit of a vertical flat in that location. Might be worth a shot with your setup.

I was thinking of something like that. Maybe someone with a fab shop would make something plug and play...
