Catch Can Routing Diagram for Turbo

[SeaCompiler]

I am preparing for my single turbo build and I have been reading a lot of different threads about how people have routed their catch cans, which appear different for supercharger versus turbo. I have located a diagram on the LS1tech website that matches what I believe I need. I just need someone to chime in if this is wrong, or confirm it looks accurate. Some run a separate catch can for the breather on the valve cover - any thoughts on that?

Nope. I wouldn't do it like that.

Get a mighty mouse can and talk to dave. You probably want a dual input can. Having the turbo suck from the valve cover is just going to draw a ton of oil/crap into the turbo/intake system making the catchcan almost useless.

You want valve covers and valley plate going to the catchcan.

Here is a PCV routing document from MightMouse and while it was specifically designed for me but it may help. I've had zero problems with my MM single PCV setup.

I run my turbo car with MM can just like the diagram drawn by Sakudog. I have also run the diagram you posted from ls1tech. No problem either way.

That will work but on a single inlet can its better to pull from the unrestricted valve cover and have the vally plate as the fresh air because it is restricted

Thanks. When you mean the valley plate is restricted, its outlet is one-way?

Thanks, that is very helpful. I have taken your drawing and attached two modified drawings below. Rather than just install a catch can, I want to better understand how the flow works under vacuum and boost and I have a question on each of my drawings which would be helpful to understand. I think not knowing how the valley plate flows, is my underlying issue.

Thanks, I have read stories where other intercoolers became filled with oil. I plan on talking to them. Would a T-fitting joining the two valve covers going to a single inlet be the same as simply having two inlets?

i have mighy mouse catch can. i used his diagram when i had turbo and it worked fine. the diagram is on this page.

The valley plate is baffled does not flow as well as the valve cover which is free flowing

[Sakudog]

The valley pan breather should be pulling air in at idle to help equalize and replace the air being evacuated via the valve covers & tb path.

Under boost the check valve stops air flow back into the catch can.

The valley pan is not part of the intake system. If this is getting pressurized at idle or light cruise well you've got bigger issues.

This is a street setup. I would contend that for something like road racing with extended high rpm engine operation, MightyMouse would recommend something else. In my case it has worked flawlessly.

The diagram is from MightyMouse and he has a much better way to explain how this system would work.

I would highly recommend spending the money to buy his products they are very well designed.

I have a MM can also. He told me to run mine like this:
Each valve cover has a 10AN bung to an inlet on the can. PCV valve back to intake. I had a 10AN bung welded on the valley cover and it will "Y" to each CAI tube pre turbo. The factory valley cover port is blocked off.

While what you have is almost identical in terms of logical flow paths to my setup it is much more substantial.

Way to out water burger me Bro!

Your eloquence has made my day with laughter!

Thanks, I saw this same post in another thread and checked it out. It looks like an amazing product no doubt and beautiful, but unfortunately for me, it is priced out of my range for catch cans as it is nearly twice the cost of the solution "full of seaweed and dead hookers" (Unreal). Mine is a street setup with only occasional boost and I don't think I will need as sophisticated of a solution as this one right now but I love your products. I know this one contains the air rather than vent it to atmosphere, which I like, and something I can review later when my next HP surge arrives.
