Cusco Catch Can Install

[omniruss]

Been looking all over the web to find a good way to install Cusco catch can without having to remove cruise control. I came across this one but wouldn't you know the picture links don't work -

Do you know of any success stories with catch can mount points, and with pictures? I have Comptech supercharger, so my options are limited.

I'm looking for a solutions as well, I have a vortech. I liked the install near the battery, but that can appears to be custom made

I have Vortech also and here's where I mounted mine. I used several sturdy sized zip ties. It's been holding for years.

How often do you need to empty it? It looks a little tight.

My other question with Cusco catch can since the instruction are in Japanese - does it matter which direction the air flows?

[repiv]

I empty mine twice a year - once in the spring and once before winter. With the amount that comes out, I could leave for a year. If you track the car, you'll need to do it more often.
Yeah, it's tight, but the alternatives are few. Otherwise, you'd just yank out your CC, right?

[omniruss]

Dunno, I'll have to fiddle around with it. Sizing it up, I think I could mount it sort of between s/c and aftercooler by using fan shroud mount points. The only thing that would be close is the hose that connects intake elbow to aftercooler. Since we're here, could you explain the purpose of that hose?

Not sure I'm picturing what you're refering to.

The only hose off the intake elbow is the one going to the valve cover front breather and I've now got that "T'd" to the catch can (since this picture was taken). There's only the coolant lines going into the aftercooler and the one vacuum line running to the BOV.

[omniruss]

comptech elbow has two - the one leading to the aftercooler I think has a vacuum valve on the bottom of the elbow.

Ahh, Comptech. I believe that hose is where the pressure relief dumps the compressed air. CT utilizes a "pressure release vavle" compared to VT, which uses a BOV. Same sort of function. Where VT blows the pressure via the BOV through its filter and out into atmosphere, CT feeds it back into the intake.
That second hose feeds the airpump. VT puts a little filter in the hose that feeds the airpump.

Makes sense. I just came in from tinkering and I'm confident I can mount the catch can on the fan shroud mounts. My next problem is that I ordered the S2000 version of the Cusco catch can. They sent me a 15mm inner diameter hose.... the pcv is 7 or 8 mm inner diameter. Does it make sense that I need to buy an adapter?? I want to hook this up to pcv valve and not the breather hose. Guess I'm confused on their intent.

[repiv]

Looks like you'll need a reducer. Use a little rubber sealant to ensure no leaks. Is the supplied hose that sort of translucent plastic with the braided threads inside? If so, don't use them. When they get hot, they will collapse when under vacuum and prove to be useless. Replace them with firm, thick walled black rubber hose like what the PCV hose is like.

[omniruss]

The hose is translucent but it's not 'braided' - it has a spiral metal lining. The way that I want to hook it up will result in positive pressure on the line instead of a vacuum anyway. And please correct me if I'm wrong, but I plan on plugging the pcv hole on the intake then routing the line from the pcv valve to one side of the catch can, and the other side of the catch can will Y in with the breather host leading to the intake elbow.

I guess that will work, but you will still be pushing some oil vapours back into the intake. A catch can isn't 100% effective in taking all oil out of the air. I believe that a typical closed system Cusco catch can is meant to use manifold vacuum to draw vapours out of the PCV valve when under engine braking mode. It seems you are using it as an "open" system catch can. You would be better off plugging the hole in the intake elbow and installing a small filter on that other side of the catch can. Run a hose from that "outlet" of the catch can and put a small filter a little higher than the catch can.
What have you done with the valve cover front breather line? That still needs to go somewhere and under certain operating conditions, it can throw out oil vapours, too.

[omniruss]

I considered several different hook ups, the reason I went with the one I described is because I'm concerned that my pcv valve is failing under FI, and I don't want to throw in a krankvent. I'm getting oil out of the breather line, so I was going to monitor it for a while after I had the catch can on the pcv line to see if I still get oil residue inside the intake elbow (must be due to excessive blow-by) or not (pcv was failing.) Perhaps I'm over analyzing and my theory doesn't hold water? I probably ought to just go with an open system, end of story, but I really am curious what's going on. From what you said it sounds like it's not going to be that definitive.
