The correct way for high performance engines is to measure crankcase pressure using a 2-bar map sensor
here is an example at 800rwhp

Notice that even with a vented setup the engine experiences 2psi of crankcase pressure in boost
you CAN'T just run a vent. That is archaic method (1970's)
Imagine you hook up an air compressor to your crankcase and set it to 2psi and walk away... how long until you start to see an oil drip forming at all the seals?
step1. measure crankcase pressure with a data logger
step2. adjust orifice diameters and connect the pcv in a factory orientation until you achieve desired crankcase pressure drop of 1 to 3" Hg of vacuum
step3. profit
