The definitive "How do I catch can?" thread.

No- I haven't bought it. Like most of these, you really don't know until you have it hand. But I was considering trying it out at some point.
There's several different brands to choose from and they all claim to "all copper". The one above lists:

Looks like a good find. However, might the large, flat surfaces of the Chore-Boy be better at coagulating (maybe not the right word) the oil droplets.
ETP is a bulk material, not a coating. I did not see a weight mentioned. I suspect it is solid copper. Home Depot Racing says it is. Basically electrical wire woven to shape.
I'd like to see a slow-motion video of the machine that produces this stuff.

I'll add my setup to the collective. I did a ****-ton less research than reading this whole thread and went with the KazeSpec can - two chambers, one with vacuum source and one VTA. I'm running the Rotrex, so standard routing didnt apply - instead of using the IM as a vacuum source, I tapped into the supercharger intake. No reason this configuration couldn't be used for any forced induction setup... just not sure if it would benefit anything.
I'll totally admit it though - I had no good reason to actually employ a catch can other than I wanted to. The motor is a brand new forged longblock that hasnt run yet, so this is still in the build phase and has not been tested. Vent hose is routed around the back of the supercharger intake for now.

I may have found an alternative to the copper scrubbies- copper mesh for rodent control. $9 gets a load of the stuff.

Roughly 5,000 miles and counting. It was an update/upgrade from the 2006 iteration with the copper mesh, not a fresh build. Looks fine on the outside and like new on the inside. Drilled and threaded fine. Yeah it's a street car, but we're talking about southern heat/traffic, 6 hour road trips, and lots of boosted runs in those miles. That must mean engine bay temps are in check and it's still strong enough to hold vapor. So surely it would work for an autocross car. As long as there's no cheater bends.

Was planning on doing the following single can setup:
\
The idea being that:
- Air doesnt flow from the crankcase directly to the breather (as it will soak the vapours)
- Normal PCV functionality remains (air doesn't get pulled from the breather in the can due to the check valve)
- Blowby gets vented to air via the catch can
- Under boost the air doesn't get vented or make its way into the crankcase
Does this setup make sense?

Okay, took some more time to think. I guess in my head I still wanted to get the negative pressure from the IM when needed - but I guess that's not really required if you just route both connections from the crankcase to the can (which has a breather) and plug the hole in the IM?
