Well I mean, the pcv is kind of already fully open when the manifold is under vac and closes as the manifold pressure becomes greater than the pressure in the cylinder head.

Not true. It's fully open the closer to atmospheric, with more vacuum the plunger reduces the flow as it's sucked up against the inlet. it only closes completely with boost.

you're not sure im trolling because im suggesting if you open a huge port to atmospheric on your IM, behind your TB, you will idle at a very high RPM?
My simple question was whether or not that'd be stupid on a BP that won't see more than 18psi at the most. If i want to go over that, it'll be on a built motor and i'll re-visit the subject at that point. :party: |

What about the MSM PCV? |

I think he means capping it off lol.
What about the MSM PCV? Hence the questions. :makeout: Is the MSM super awesome or something? I know on other motors we used to snag the 323GTX PCVs because they held up better under boost in theory. |

I'm a little offended that you think i'd be stupid enough to not plug that hole. IF i do this, it will not be the first time i've removed a PCV system entirely. But previously that was on motors ingesting well more than 20psi of boost. (WAY overfilled, you know?) :giggle: Or on a motor that no longer had an intake manifold.

I'd just let the factory catch-can do its job.

I have an MSM with an upgraded turbo that's about to get tuned @ 15psi or 250wtq, whichever comes first.

There's some issues with the factory catch can and how terrible it is, but for my street car, not likely to be a problem. |
i mean, the same can be said for the MSM turbo setup and ECU alone... so.
