Ok so I know this has been discussed a million and a half times and I've been doing quite a bit of research on the matter. I see most guys have tend to run a line from valve cover to can and black box to can with filter on top of can. I was wondering if I would get proper ventilation if i cap off the black box and only run off the valve cover. I am currently building a turbo Z6 and plan to break it in NA. The catch can I have only had 2 ports aside from the filter. I was hoping I could get away with running one to valve cover and the other to intake manifold while I am NA and then running 2 lines to valve cover once boosted. Will it be ok to run like this? Thanks.
