Crankcase Vacuum

[threestar40]

Anyone want to talk about crankcase vacuum in a forced induction application?

I know about venting through the valve covers with with breathers, but in a turbo application, would it be prudent to use a vacuum pump and if so, how would it be plumbed exactly.

I've seen the set up many times in a race application, they just dump into the headers, but in a street application, that would obviously be unacceptable because of the unavoidable oil that would end up in the exhaust stream.

Thoughts?
