I am currently completing a design for a custom intake my car.
I am just after some confirmation for my current line of thought.

The engine has the pcv system going through the standard intake and I am incorporating this into my own design.

Am I correct in thinking that the volume that the pcv system uses wouldn't make all that much difference? Due to size constraints I have had to make the volume smaller but still connects to the original attachment points.

The pcv after all is just a vacuum chamber after the valve, so if anything, making it smaller will mean the vacuum would get up to pressure quicker? Thus not making a difference in how the system works?

It's more a matter of how well it flows ie the cumulative restriction along all the hoses, rather than how much volume the hoses contain.
