Who's running a catch can?
 

Who's running a catch can and did it come with your kit or did you rig something up yourself?

Only one I've seen so far is on Bullits car.

I don't remember seeing that, do you remember what pic it was in?


Biggest thing with a catch can on the VHR is the dual breather setup. You almost.need something custom to work well.

I've been running two "home-made" catch cans since day 1 of TT upgrade. When I was installing the turbos, I noticed a layer of oil accumulating in the intake manifold. Since installing the catch cans, I've been catching ~ 2 tablespoons of oil per 1000 miles.

Are you on the fresh air tubes, pcv, or both?

I have one

We offer Catch cans in Blue, Red, Silver and carbon fiber :)

I'm not F.I. but i'm running a GReddy catch can. It's mounted on the driver's side between the intake pipe and radiator fan.

Here is one at Baker Tuning! Top Secret Ti Catch Can. This TTed Z has two of them!

Seems like as good a thread as any to report on my catch can results from driving so far. My can has been on ~2,000 miles, and I dumped it last night for the first time and measured it. It collected 1/4 cup almost exactly, which matches perfectly with the "2 tbsp per 1K" modme posted above, and "1 tbsp per 500mi" someone posted in another thread.

My car is NA, so apparently FI doesn't really increase the catch can fill rate. Looks like engine oil but a little thicker and darker than mine looks when I drain it, leaves a greasy residue, and smells of fuel a little bit, which I guess makes sense considering it's condensed crankcase vapors.

Mine's running on both PCV lines. The fresh air tubes should be bringing fresh air into the crankcase, not venting gasses from the crankcase, so I don't *think* you need a catch can on those. Since we have two separate PCV lines, you'd need either a can with 4 connections, or two cans, if you want to leave everything else about the PCV system bone-stock.

As it happens the M370 manifold from Motordyne requires to you tee-adapter your 2x PCV into one vacuum connection anyways, so that made a single can setup on my car a no-brainer. Even with the stock manifold, you could tee them together, run a single can to one of the original inlets, and cap the other off. Just a matter of what you want to do with the hoses.

Can some of the guys that have done this think back and write up a DIY for those that would like to do this, but don't wanna cut/swap the wrong hoses to the wrong spots and making something simple a big problem? :tup:

I've definitely seen a catch can in a few TT Z's down here in Florida.

:iamwithstupid:

i guess the real question is, do we really need to have one? Like what are the Pro's and Cons of it

Pro:
-Prevent oil from gunking up the MAF sensor and throttle body
-oil will lower the octane level of gas in the engine

Con:
-Cost of the catch can
