Ok, I've searched and am still confused.
I understand why you need a catchcan and all that
BUT I don't understand why i never see them in pictures, when people talk about their set-ups, and most notably, when I see pictures and parts lists for turbo kits. So, my conclusion from this is that it's not necessary at low-ish boost? If this is so, at what point does it become necessary? If not, then why is it that I never see these with set-ups designed for stock engines?
Thanks for the clerification.

 

It doesn't really add to hp claims, and it makes the kit "take longer" to install, and it's extra cost over the base price for a turbo setup. So there's no much sexiness in selling a correct PCV system with a turbo kit. That's not to say it shouldn't be included, but there's not a lot of good marketing reason to include it.

 

But I know a pretty good number of people run turbo kits right out of the box and I haven't heard of anyone having problems because of a poor PCV system.

Also, can't you just run the catchcan system without the catchcan? It seems to me like the only downside of this is more oil in the intake air and therefore a lower octane rating, but will this be a big enough problem for say 10psi?

 

this writeup explains it pretty well

You've never heard of broken ringlands?

Yeah, the first link is how I know everything I know about this.
As for the Endyn kit, that seems to be the recomendation I always see. It just looks so expensive for such a simple thing though...

Yes, the endyn setup aint real cheap. But it did cure the little bit of blowby I was getting.

The one thing I learned is if you want reliable power, you gotta spend the cash

 

Hey guys i have read that article over and over and cant figure it out...it says putting a breater on a stock system would possibly be the worst thing to do can somebody explain why this is.? i just cant figure it out

 

please help

 

???

 

ok here is how i see it, and how my setup was done.

when there is positive pressure in the manifold, the pcv valve does not open. this causes the gasses and **** in your crankcase to remain there/ or vent out the block via the breather on the valvecover. in stock form, this is attatched to the intake pipe(vacuum source). something about a breather has pressure differences or does not vent the crankcase as well, so it should not be used on the valvecover. i believe the proper catchcan setup runs from the manifold to a pcv valve in a catchcan, then back into the intake pipe. it can also come from the back of the block if you have it fitted with nipples to allow hoses to drain it.

now im semi cheap, but wanted at least something, so i got a catchcan from http://www.roadraceengineering.com for like 49 bucks. i ran it from the valvecover nipple to the catchcan, then back to the intake pipe right before the compressor wheel. i cant say how effective it was over time ,cause my car got jacked a few weeks after i turbo'd it, but from what i read this is a semi worthy alternative.


here is a pic of mine mounted under my bov. i dont think ou can see the hoses running to it, but i already said where they went/came from

You could've just ran BOTH the PCV on the back of the block and valve cover to a breather filter and skipped the can altogether. Would've been cheaper.

 

Iv read alot on catchcans and it just confuses me everytime.

 

i just filtered all my pcv system hoses with air compressor filter set ups, and clear hoses to see how effective it was, 2 filters only cost me 20 dollars from lowes, works likes a champ

 

what are you guys without Filters or intake piping?
