This is great info. Five years ago or so when I started going to bracket racing comp I was always intrigued by these catch can setups and how some people, that seemed to have the taste cars, "6" seconds, had pumps to pull the pressure out of the crank system. These were all motor from the lot that I was around. I would assume the benefits would be minimal on something more streetable but was wondering what you guys thought?

If you want to keep the stock PCV system and get the benefits of a catch can, its even easier.
Intake side leave completely stock.
Exhaust side run to a can.
Then have a breather on the can or run a line to the turbo intake pipe, just like the other setup.
The PCV setup doesn't evacuate as much pressure as the first setup because the pcv closes under boost, so you only have pressure escaping the exhaust side when under boost. for normal setups this is ok, but when making big power or if you have issues with blowing main seals then you will want to delete the PCV so the intake side is evacuating pressure as well.
This will also keep more oil out of your intake manifold.
