No the catch can will catch very little.I've heard in my d-series after a track session you might catch 10-15mm at most.
It's hardly even worth checking for street driving,a little bit might go in there but it's oil so it just sticks to the inside of the catchcan and hoses,it wouldn't even fill up at all on the bottom.
I drive my d-series to redline 6,500rpm all the time and just a dirty catchcan but no oil on the bottom as such.Most people take them out after a year cause they would raher the engine space or it's not doing anything.It does stop that crap from going in your intake manifold but big deal really.I'm just a clean person.The only reason I put it back was cause I'm gonna track it.
