Crankcase pressue problems with F/I applicatiions
I was looking at doing a supercharger kit for my 2015 Z51 A8. I was told that if I am going to do the blower I should definitely do longtube headers as well due to backpressue issues. I really didn't want to do headers but If it's a better set up I will. My problem is the more research I do I keep running into people saying the C7 has a big problem with crankcase pressure. Maybe ECS can chime in hear and let us know what the answer is. I would like to do their kit but I wan't it to be reliable and not having to worry about stuff breaking. Anyone else know about the crankcase pressure or if there is a fix?? Thanks

All the supercharger manufacturers seem to have figured out the solution, and have it included in their kits. Since you're near ECS, take a look at their instructions to see their fix for it.

Did i read that correctly
It stated the afe intake CAN NOT be used with a procharger / ecs supercharger?
I picked up a AFE intake and ARH headers thinking i was getting the base components for a supercherger to drop in on top of. Seems like i wasted 500$

The AFE or any other intake for that matter are NOT usable when you go F/I. It's always been that way.

Plug & play, no, but I have seen guys customize the intake a bit to make it work. If I were to add a Procharger to my car I'd fab up an adapter to allow me to retain the AFE airbox & air filter.

There are cars floating around all over here making up to 1000+HP with the ECS kit. Well beyond what most look for and they are running the standard ECS supplied ducting from the air filter to the blower and then the engine. Some running the standard ECS crankcase vent routing. Some choosing to go with something different although not necessary especially for a standard install.

Never any harm in removing a restriction, which the stock airbox and stock sized filter is. This is the reason Procharger offers a "race inlet" option. The C7Z breathes through the same box as the C7, but look at the gains people have already found with the AFE & Halltech intakes. As far as OEM intakes go, the C7 design is very good, but does still have room for improvements.
