Position of Catch Can

Hey does it matter where I put the catch can? I want to put it up by the light because that is the only place I really have room. But this would make the line from the head to the can about twice as long as it is now. Does it matter?
 
i was thinking about getting one and the pics I have researched mounted theirs on the outside wall right under where the stock airbox would be, I dont know how long that makes the tubing, but I don't thinkit would really be a problem and it might be closer than the idea you had and I think it would be at more of a downward angle, so there wouldn't be much of a chance of it backing up. thats my scoop if i get one, let me know how you go about it and throw some pics up too.

IT doesnt matter at all where you put it, except for two things:
1) the point at which the tube enters the catch can must be lower than the point where it leaves the radiator (this is virtually impossible to mess up unless you put it on the hood, lol)
and more importantly -- a lot of folks DONT do this,

2) The catch can must have the tube attached to the BOTTOM. Race cars only need the "catch" can to avoid spilling fluids on the track, it's a true "catch" can. Ours is a RESERVOIR. In other words, not only does the motor shove extra coolant in there, but can, at times, suck coolant back out. without this, if the motor starts running hot for whatever reason, you dont have that reservoir to keep you going that much further. Anyone who has changed their own coolant has seen the coolant system suck the reservoir dry as you refill it.

Every time I see someone who bought the aftermarket catch can post pics of their engine compartment with the tube at the top, I cringe. Your motor will run fine like that, but if you need the extra coolant....too bad.
 
Oh, and BTW I have a cheap ($4) plastic aftermarket reservoir mounted down on the driver's side frame, above the tranny, below the injen intake. I just had to move it for the intake. Looks fine, took 30 mins to install.

will you throw a pic up? i am interested in your setup. thanks in advance
 
Hey people...I am not talking about a coolant reservoir...I am talking about and oil catch can....:) You know, air comes in one side and goes out the other and oil is dropped in the can....

thats actually what i was refering to, i just wanted to see pics of the cooolant resevoir. my post still applies for the OIL catch can, I like the PERRIN oil catch pan, mainly b/c its black.
 
According to cullen, if you push the battery back, you can mount it right on the end of the battery plate and its perfect... I dont have an engine or battery right now so I cant verify this, but its where mine is gonna go!

I just made a custom bracket, no need to remove the battery tray or anything.

Not trying to threadjack, but I was looking at your picture, how did you polish your minfold cover like that? looks good man!
 
I actually just did that last night. I have a 6" grinder by Crafstman and I bought a polishing wheel for it along with the polishing compounds. Put some compound on the wheel and carefully move the manifold cover over the wheel. Took about 2 hours and about 4 passes over the wheel.

Thanks for the compliment. I think it turned out well also. Cheaper than chroming - FREE!

If you wanted to me to do yours, I would do it for you, for a small fee though.

Can anyone confirm that you can attach a greddy oil catch can by just pushing the battery back a bit and installing it there.

Whos car is this? I would like to talk to them about how to hook up the hks grounding kit. I have the same one and cant figure the ******* thing out. Sorry thread jack over
 
It doesn't matter how long the lines for the catch can is. It will still serve its purpose. I have the Cusco can and there is a hole where the pipe goes into the fender behind the headlight that perfectly fits the bolt so you don't need to drill anything. Just make sure that you hook it up correctly because it irks the hell out of me when people say their can doesn't fill up when they have it hooked up to their intake.
 
Not sure about the above statement. As far as I know the catch can should be between the crankcase ventilation nipple and the intake. The crankcase breathes out to the intake and pushes oil vapors along with it which can accumilate as oil in the intake tract and work it's way into the turbo and intercooler and piping. A catch can mounted between the crankcase ventilation outlet and intake will keep the intercooler from gumming up with oil and needed to be removed and cleaned over time.

This is the way mine is hooked up and is working fine.

I cut this out from a Mini website.

"Supercharged engines are prone to accumulation of an oil sludge mixture forming inside the intake tract. This is a result of crankcase pressure and inefficient combustion. While this condition is normal it is a hindrance to making higher horsepower and increasing engine longevity.

Oil vapor is forced out of the cylinder head and redirected through vacuum hoses into the intake stream. The oil will then condense onto surfaces in the intake system. This is especially prominent in the intercooler core.

The ALTA MINI Performance catch can will hold this oily byproduct and removes it from suspension in the intake air stream. Horsepower is increased by eliminating the engines current requirement to try and reburn this relatively noncombustible oil. Engine longevity is lengthed due to this oil not having the ability to gum up the valve train, supercharger, and various other moving parts and sensors. Intercooler efficiency is also increased. The thin film of oil coating the inside of the intercooler will insulate the air to air exchange and lower the ability of the intercooler to cool the intake air charge.

Valuable for daily driven street cars but truly a must have for track cars and cars with our high boost supercharger pulley. Easy to clean, empty and maintain. A built in fluid level gauge will visually show when to empty the catch can.

Catch can body is constructed from 3 ply high temperature silicone. Included vacuum hoses are made from extruded silicone composite. All hose connectors are constructed of fiberglass reinforced ABS plastic and are rated to 400 degrees. Canister is available in Black, Red or Blue."

the intake is what causes the vacuum that pulls the oily vapor off into the catch can, the above statement is the one I'll always heard. I dont think the pcv valve would have anything to do here.
