The turbo inlet is the best source of vacuum at WOT.

How long are you staying at WOT? You are going to build up some gases at WOT from blow by. But you are going to suck them right up once you let off.
I do not understand why you guys are trying to re-invent the wheel. Quality Rings and modern piston clearance. I don't see how you are going to have major blow by.
Only gain I can see is an extended oil change intervals. Yes you can increase power by installing a PCV system. But, the motor already has one.
Splitting hairs IMHO.
