Rough idle with forced induction

Mitco39

My car has been at a detailers all week and my cable is in the car so I havent had uprev infront of me for a bit.

But if you were going to route that vent back it would have to be under a vac only condition so you dont pressurize the crankcase more than necessary.

You could do this via a PCV valve so that when your under boost it keeps the boost out of the crankcase, but under vac it sucks in the crankcase emissions. I had it all figured out in my head last year and there is a thread that I believe I started on it. I will dig through it and see what I can come up with when I get time.

Although I personally think if we had access to the IAC tables we could tune for the idle. I also believe the VVEL does not help us. Does anyone have any experience with say sashas kit on the 350Z where the crankcase ventilation is also routed in a similar fashion?
