I'm sure most any catch can will work, be cautious of the tubing supplied with some of them. The VQ pulls a decent vacuum and cheap stuff will collapse.

 

for $25 I would get the one you posted... there isn’t anything mechanical about a catch can - they are just reservoirs with hose fittings – so its not likely one is better than another other than looks (and possibly quality – but again, its just a reservoir – pretty hard to screw that up)… the one you linked looks similar to NRG.

Like rookie said just make sure you use good vacuum hose, but it sounds like you have that covered.

 

A few cans are more functional than others.

ARC cans have baffle plates behind the oil ports so the oil vapors should collect onto the plate before the vacuum side.

SARD can one of the ports goes in 1/2" or so vs being flush with the can, this should allow for the vacuum side or oil side to not be directly ingesting each other.

Essentially they are all the same, if the ports were directly across from each other it may mean more vapor is not caught. But whatevers.

 

^^^ cram some steel mesh down there... that’s what I'm gonna do

My home depot catch can has fittings directly across from each other - I was initially concerned that the vapor would just shoot directly across and back into the collector... but that thing fills like crazy so I the theory that the vapor becomes liquid when it comes in contact with surface is correct... or I'm catching some of it and a bunch is still getting through. The last time I took plenum apart it was dry though (as oppose to no catch can, it was oil laden!).

I do like the idea of baffled can though - but I'm not certain it will fill quicker or better than non-baffled.

 

I wouldn't just shove it in there if it can't remain in a somewhat clump of a piece. I'm sure someone has done it and it would be ok, but steel mesh pieces being sucked around kinda worries me.

There are cans that can be dismantled and controlled placement of steel mesh can be put into the can.

 

HomieG35: Aren't you all about authentic parts too? Shame on you...STOP THE COPY!

 

Get the Ebay version bro.

When you do, you will need to take apart and use teflon tape on all the threaded connections...


Use a thing of steel wool to "filter" the air and you should be good to go.

Fact is, a lot of the vapor will condense in the down flow already.

 

When it comes to what hose to use, get something like bradded hose or fuel injection hose. You need to make sure it won't collapse under vacuum.

 

+1 on the hose. Any fuel line from Napa will do. I dont recommend the steal wool either.

 

If you get one form ebay, make sure you break it down and put it all back together with sealing tape ( i can't think of the name now). They do not come air tight by any means.

 

I was initially concerned about steel wool - and used to post the same concerns about bits straying... but several ppl (primarily found on 350z side) have reported using it without issue... I may try - and keep an eye on it... or just as likley to use with nothing, as that has worked well with the can I currently have.

 

yes use fuel line hose. If you want to help condensation with a mesh get a $1 copper mesh pot scubber and cut a piece off to shove in there. Less dense and takes up less volume than steel wool and offers plenty of surface area to condense on.

Looks better in a clear can too.
