The bottom opening between the throttle blades is for feeding the IAC.
Yes a supercharger would change the pcv works, along with every other vacuum controlled circuit. But that question was never asked.
Believe whatever you want, and go ahead making up stories and repeat them until people believe you. I have better things to do.
Seems no matter what is said mate it will fall on deaf ears. Cant help that i spose eh. Not like as if we didnt try though!! Quote:

Fact, new throttle bodies have the air foil made right in. Fact, new throttle bodies have a hole for the fresh air PCV system.
Picture:
Fact, the air foil of that type totally blocks the fresh air PCV. But could be modified to work well. The mounting piece of metal is made to only take up half the diameter of the fresh air opening. A hole could be drilled in the air foil to let the system function normally.
In regards to a breather for the fresh air, some say that is unmetered air on a MAF system and should be tuned for. Others disagree.
That design in your first picture i have NOTHING against, i think its a good design, and it clearly retains an adequate opening for the PCV system.
Im glad you posted this, cause it seems everyone wants to have a crack like this ( not saying you are though ) with the new TBs having it intergrated, or the LT5 TB having it intergrated, but this is not the point, the point is the conventional and seemingly most common design of screw in airfoil has potential to block a PCV system.
