I would imagine that you would want a constant flow of air in one port, out another. With that center iron nipple capped, the only source to relieve the vac is the blowby or the oil entering the pan. I would imagine that it would be a little more effective to leave the iron nipple open, but filter the air going into it, no?

Interesting point...
We were just worried to keep the pressure out of the crankcase.
The point was just to relieve the pressure.
I wouldn't think circulation would matter.

This is exactely why I wanted to run the vac source through the filtered puke tank before it heads to the turbo. Was also thinking about running a clear fuel filter inline as well just as a last ditch effort to catch anything that migh do damage hitting a comp wheel spinning way too fast. Like you said, purely vapor would not be a problem, but some sort of debris or the sludge that often collects, would be a huge problem hitting those comp wheels under full song.

Ah, now I see why your design is so complicated.
It's sorta like running a "charcoal canister" system for the crankcase evac...
Yes, what you are proposing does make a lot of sense.
It looks like you've got all the bases covered - condensation of vapor / moisture, drainage, and purge to combustion.
The clear lines are a plus - this is why some (Japan) racers like to use those clear lines: to inspect the crankcase puke.
I've got mine current T'd, and you're right - there's a LOT of puke that comes out of those lines.
I had my hose pop off my pipe prior to the turbo inlet, and there was a LOT of disgusting coffee / mud colored liquid that came out of there.
I'm too lazy to redo right now, and the stock turbo puked it's seal a while ago.
When I change the turbo out, I think I'll redo the system too.
I like your plan of attack on this matter, and it should work.
I think it's just a matter of having enough volume in your catch can system...
We also know how tight space becomes in the FC engine bay with big turbo systems and FMIC's!
