Pcv's are a vacuum leak however you look at them, modern stuff's computer's deal with it fine, it's a bit of a job trying to get a carburettor to deal with it.
Obviously the oily air gets burnt in the combustion process, but it still lowers the resistance to detination (sp?) as does the vacuum leak. This ain't really a concern on a naturally aspirated engine, but bring a supercharger to the party and the needs change. The importance of clean air and good gas goes up massively.
All that being said, with a supercharged engine why make it more prone to detination? A step in the wrong direction I feel.
You can imagine what you want.

I have had an AF gauge installed for some time and there is not any detectable difference when the PCV vacuum is disconnected. (no imagination or speculation)
