valve covers?

Pp would be the power pipe.. I believe it had a fitting for vac its been a while since I looked at one.

Only fitting on my powerpipe was for the bpv to dump back into before the supercharger.

I had one shortly and it had one on there. Might have been modified. Can't remember. If they have no vac fitting. It's Back to the drawing board for me.

Then there is always a vac pump

There are actually 2 different pipes. One has two metal pipes, intake to the charger and between the charger/intake and that one has the valve. The one I have is just the intake to the charger and doesnt' seem to have anyplace for a vac line but there is a large rubber boot that has a hole in it that looks like a line could fit in it. IT has a mounting spot for the AIT in the metal so I think this hole is for the vac but if not I could put one in the boot easily.

The thing with pcv is you either keep it open. Like the first pic.. then if you do run a closed system. You need a vac source. It has to be pre blower. Anything after the blower will be under boost..

also needs to be kept after the maf.

ttocs · Jan 22, 2014

understood. But nothing wrong with poking a hole through the boot, after the maf/before the blower and sticking the vac line through it right? Rubber/rubber should be a good seal if the fit is tight and I don't think there should be enough vac to suck it through.... I need too look closer through it all and will when I mach it up its cold as balls right now as much a I want to do it all. Was disappointed to se the high will be 10 tomorrow.

I wouldn't poke rubber.. Crap tends to expand over time you know..

I'm actually curious to see what opal thinks

ttocs · Jan 22, 2014

don't think I would need too as I think that is what the hole in the boot is for. It looks like it was molded with the hole there as there are grooves in it that would seem to be good for sealing and holding it in place.

rz is pretty much dead on...Although his crude diagram has me confused.
The short and simple of it is your either going to run an open system and delete the pcv or a closed system with a boost capable pcv or closed system with a vac pump. What works for you will be trial and error and will depend on what condition your motors in. Remember any blow-by will be magnified 10 fold with the blower.
Since you already have a vented can you might consider getting rid of the pcv and going a minimum of -10an off each VC to the catch can. Will this be enough for your set up IDK youll have to run it to find out. If not youll have to experiment.
If you decide to keep the pcv youll want to pull vacuum pre blower so yout not boosting your crankcase. youll also want to swap out the stock pcv valve as it will leak boost by it. A valve from a mid 80s super coupe should be fine or any other valve specifically ment for a boosted application. I wouldn't suggest putting any fitting in a rubber boot.

Yeah my artistic talent is very limited.

Why not get them done in hydrographics? My buddy just started a business and has lots of options avalible!

ttocs · Jan 23, 2014

the catch can come both with the breather filter as well as a bolt that can be used to make it sealed. Sounds like it would be easier to start with the closed system and keep the pcv in its place for now? What problems would I have that I would consider the open system?

Thanks but I already have a custom idea in mind.

Crankcase pressure and blowby are going to be the main concern with the blower in regards to the pcv set up.

the motor was replace about 15k miles ago with a rebuilt motor from jasper eng/tranny's if it matters. Thanks for putting up with my questions...

That's a plus but Im sure they didn't gap the rings for boost so youll still be contending with some blow by...how much IDK, but youll find out. Like I stated earlier your gonna have to experiment on what pcv/evac works best for you.
