line size is important as power and piston assembly clearances increase
3 cans and still no pcv sounds like a bunch of cost and complication for less than ideal function
in a performance based application, sending all the blowby back to the engine to ingest, vs allowing it more clean cool oxygen rich air will result in less power, even at the expense of the natural scavenging to the air intake. we are talking only 1-3" vac here (remember we don't want a lot or else your air filter is also costing you hp). compared to 15" or so with a mechanical pump (that still only gets you around 10%)
so roughly the math says it is less than a 2% power increase, and that is assuming the air is not contaminated, which it is.
in the end i setup what the customer wants aligned with what the customer needs, arming them with all the info i can muster, and they get to make the final selection.
