Not really needed, on a built motor setup with any kind of decent boost (28+) this thing catches so much stuff its crazy.

I used to have a setup like this on my car, tried through the screamer as well as the downpipe, it really doesnt work well, still blows the dip stick everywhere.

I run this setup with my 2.4L Ported head on EF4 making 560whp (30psi) on a mustang with the 10an race hose setup. Im glad the can isnt any smaller as I can fill it up from a tuning session and a few track passes, it works...

I have tried all the other solutions on the market for the most part, with the race setup (10an), My dipstick stays in to say the least, my car also picked up around 40whp over stock PCV setup.

Turbo stays cleaner without re-venting it in the intake, which means it will last longer, alot longer.

 

alright i have a few questions. i am looking into getting a catch can in the next few days and some of the things i am wondering about. are the breather filters really necessary? as i see alot of the catch cans (ex: cusco) don't have them. my other question is how often these things get emptied/filled. or does it depend on driving style/engine load?
(noob flame suit ready. not on yet)

 

The Filter is mainly for releasing pressure in the system to help create the vacuum if your not going to use a line goin to your intake which causes the pull of the vapors from the valve cover...

It gets emptied based on how you drive really but responsibly should be checked maybe once a week. If your dipstick is blowing out the youve defiantly waited to long

 

I had a mishimoto catch can on here before but then I took it off. It didn't have a filter and it didn't perform as good as this set up. Do yourself a favor and contact these guys for the last catch can youll ever buy.

 

I think it depends on what kind of lbs/min/condition of motor/built with loose clearances if you need one of these or not. I have a saikou michi (sp?) can with baffles and steel wool inside, and I my dipstick has never gotten pushed out with the stock fittings in the valve cover, stock pcv, and I have zero particles of oil in my intake system.

I also heard (correct me if I'm wrong) that if youre on a maf setup you dont want to use a vented can because it will draw in unmetered air when in vacuum? I have ran this style of can before with two breathers and two -10an fittings on top, and it worked great, but kind of overkill unless on a high(er) hp motor or someone with a TON of blowby.

 

Thanks for your input^^^
I dont think that the air you speak of would be unmetered on maf or sd. That steam and gunk in your valve cover never sees the combustion chamber on this set up. In stock form the air is recirculated via the pcv to the intake manifold and also into the intake tube.
My car has a built motor and is on speed density. Im sure this would be even better for the MAF guys. I was running around 32 pounds before and i had to resort to putting a spring on my dipstick to keep it put. Took the spring off the day this catch can was installed and the dipstick has not moved from its place. I don't know why i didn't buy one of these sooner.

 

If the catch can is properly baffled and filtered it will not. Well not to the degree you are implying. My can is dry as a chip (albeit I only have 220miles on this new motor)

 

Soo...where's a link to the setup you used OP?

 

FYI ^^^ this was on first page.

 

This works really well on NA cars, especially high output ones. On a turbo car, the turbo just eats to much exhaust velocity for it to be effective, paticularily with a large diameter exhaust required for best turbo efficiency.

 

Main page has update. It has been installed for almost two weeks and no drawbacks. I'll post some pics before I drain the catch can. We can check out the junk that would otherwise make its way into the motor without the catch can.

 

So with my set up (tomei arms 7960m unknown 272 cams, but pretty lopey, soon to be on ecu controlled boost and porting turbo/stock mani looking for 370-400hp) it sounds like a good catch can will benefit me. Which style/set up though?

This is an SSP tx oil catch can. They
make them for evos,Zs, and everything else.

 

with the amount of oil that is blown from the pcv on an evo, a catch can should be purchased as one off your first "mods"

 

But which is better the single or dual can set ups?
