S/C what about vacuum lines?

[rcmonster]

I am finishing fabbing up my Eaton M90 on my sn95. Do I need to plug the 2 vacuum lines under the bottom of the intake manifold? Can I just leave them attached or not? Thanks!

HELP

I am totally stuck on this until I can find out what to do with the 3 vacuum lines under the intake manifold. And, is this a PCV? What do I do with it? I circled the 2 items I am talking about. I am trying to finish the S/C today. Thanks

Has nothing to do with your question but since you are just putting it together for the first time. When you are switching to "pressurized", I would think that you need to put something on there to keep the hoses from blowing off. Maybe some zip ties, used like hose clamps? When I was running turbo 2300's, we used to use the one way valve from an RX-7 to keep boost out of the crankcase. Funny thing is, it was used in the brake vacuum lines on the RX-7. I could prolly get the part number, if anyone wants it.

I suppose you would just hook all the vac lines up the way they were, or at the very least, just plug up those holes under the intake.

I will just leave them where they are and put zip ties around them where they connect. Thanks. Hopefully pics of completed job soon.

Well, the vaccum lines that were under the intake I took and put after the TB but Before the supercharger, they never see any boost, the fuel pressure regulator and my by-pass valve and my gauge are the only things that see boost on my car.
