Re: New catchcan idea
 

why wouldnt it work?

Re: New catchcan idea
 

if you goto his new thread on turbod16 he changed his setup again

Re: New catchcan idea
 

It will work, that is how a lot of factory turbo cars come factory. Problem is if/when you start getting blowby you will be sucking oil vapor into you turbo. which in turn ends up making it's way to the combustion chamber. Oily air can cause detonation. This is one of the first things most people do any with.

if you're set on a catchcan and not venting to atmosphere
-remove the pcv valve he has drawn
-remove the red line he has drawn from the turbo inlet
-instead run the red line to a tee.
-run one lead to a check valve (pcv valve) to your intake mani (this will vent when you are in vacuum)
-run the 2nd lead to a check valve (pcv valve) to a slashcut in your exhaust (this will vent once you get the exhaust flowing)
-make sure you orient the pcv valves so you can't blow back into the catch can from either the intake mani line, nor the slashcut line

Ok I have a ebay catch can.....im not going to do a slash cut in my downpipe....---- that

I was going gut my pcv at the intake and run a hose from there to a tee......then a hose from my VC to the tee.....then from that tee to my catch can.....then from the other side of the catch can i was going to run a hose to the pre intake tube on the turbo...

Re: New catchcan idea
 

what do you mean gut the pcv at the intake and run that to the catchcan?

basically, you want to pull vacuum from the back of the block and valve cover. however you to that is up to you.

choices are:
-intake (pulls vac under vac conditions, supplies boost under boost conditions)
-pre-tubo intake(pulls good vac once turbo is spooled enough to do so)
-exhaust slash-cut(pulls good vac once exhaust is flowing fast, could supply backflow at low rpms)

those are your options, use check valves as necessary when taping into intake or exhaust.

or make it easy and point the tubes from the vc and block to the ground.

Yeah but if I do that then I smoke like chief wahoo....

I currently have something working but not sure if its good.....
I have the PCV gutted and running into the intake like normal......
and the VC has a filter......been running that for a week now and so far no problems.....no smoke....nothing
But im pretty sure im boosting the hell outta my bottom end not sure

It's not that hard to cut a peice of steel tubing on a 45, and welding onto a downpipe. Hell I used a section of brakeline you could buy at autozone. It came with a compression fitting on it so i ran 2ft of copper pipe into the engine bay, then to a barbed fitting, you can run a hose off that fitting to your catchcan, OR to a check valve if you use the setup in my diagram.
