This is the exact same setup used on GpN motors with the addition of a catch can (GpN cars just blew the high load vapor through a filtered hose at the base of the firewall).
Low load operation is not a knock-limited situation, therefore, this reduces the amount of oil collected in the catch can. The vents are not connected to the turbo inlet in the diagram - during high load operation, the PCV is closed the the crank/heads vent to the catch can which should be baffled.ĭuring low load operation, the PCV is open and the oil vapor can be burned in the cylinder. lol Can you explain?įirst, one of two ports on each head is an unbaffled air balance port - ignore the balance port. I work on my cars, but it still doesn't make sense.
This was the diagram I kept coming across, but it seriously makes no sense.
