wonder if any of the tuners can advise the best way to hook up an ARC catch can c/w with breather...?

 

The smell from my RIPS catch tank is starting to get on my nerves, so tomorrow I am going to extend the outlets to the rear of the car. Will update in a few days.

 

lewis just call Ron and he can buy in all the hoses and fixings

just done this myself

 

will do fitting the can today (putting it in place and hooking up washers etc.) so will give them a shout

leaving the system to breath to atmosphere until i go higher power as per:

 

Breather pipe extended as shown below and now exits just by the rear diff. The smell of petrol fumes is now alot better with only a faint wiff every now and then. Previously, in traffic I had to keep the windows closed.

The only slight snag now is that I will have to remove the pipe from the tank to check the oil, but that is definately a price worth paying.

 

This is exactly what I'm going to do. Where did you run the pipe along underneath?

Also do you know what size pipe should I buy? What diameter fits snugly over the cam cover outlet?

 

Here is my set up.

 

That is such a nice car, so very very nice!

 

Thanks Chris just added some more pictures in the Project Section.

 

are there any issues going from the oem breathers 22mm ID to a 15mm ID catchcan hose??
i see many have done it on this thread.


id imagine it isnt ideal, but is it an issue??



what would be involved in T-ing into one of the turbos drain feeds to drain the catchcan? i take it this drain line doesnt have "pressure" to cause any problems? similar to the nismo setup.

 

My setup

 

Hose comes off catch can breather and runs down past the steering / fuel lines and along the chassis rail. You will need to size up the hose yourself, as it depends on your catch can breather outlet size.

 

These setups don't make much sense to me lol. You have a pipe into the intake to suck the oil vapour out, but people also plumb both pipes to the catch tank with a pipe under the car. How the hell does that work then? If the intake is acting like a Hoover so to speak how do the gases go to the catch tank and the gas go out of the drain under the car? Or is this only when the intake is capped. Also by capping the intake pipe how do you get the gases out? These catch can setups seem a bit pointless without a strong sucking force.

 

You're forgetting that you have pressure in the crank case.
The vacuum from the engine does help with lowering the crank case pressure, unfortunately you also get in the oil vapor which degrades the fuel as I understand.

Therefore when you remove the vacuum you must use large enough hoses to not make it restrictive so the pressure stays in the crank case, or finds alternative routes out...
The can is there to catch whatever oil the pressurized gases might bring along.

 

Trying to decide the best option for my catch can setup, got some options.


I have a -10 an fitting welded on each rocker cover and I'm running the mines baffle setup also.





A tank like this:

Breathing to atmosphere through two filters (though with wider neck than those in the photo)


or


Same tank but with pipe to went air under the car (with oil vapour separator built into tank so no oil gets dumped anywhere) to avoid oily smells in the cabin.


or


Same tank shape, but with two inlets on the top of the tank and an outlet about 2/3 up on the side venting into the sump.


or



Two inlets on the top, vapour separator setup inside tank and an outlet plumped in the rear turbo intake pipe so theres goos negative crank pressure?



or


run these:

Universal Dual Catch Can Kit



Which setup sounds best?

 

I come back on this post to ask some help about the right way to fit a oil catch can, not the position of it but the fitting of the inlet, outlet, vent and sump return.
