7/8" is a very solid mount. I broke out the calipers and measured before I ordered.

Thank you. I will update when I get everything setup. Hopefully within a month

PCV Valve Barb is 11/32"

So according to Dezoris the hoses need to be these sizes, but what about the barbs/nipples? I notice he is running 0.425 OD and 0.5 OD size barbs. 11/32 which equals to 0.343 vs 0.425 seems to be a pretty big difference.

I'll be buying from Saikou Michi so he can fab up different barb sizes.

Using 3/8 Tubing and -6AN two piece 90 Degree Barb for the PCV to inlet will be good going forward and 1/2" for the outlet barb if you are running N/A.


Here is my finished Vortech Dual Can.

Finally Got to installing the dual can solution. Thank you @neutron256 for the mounting idea. It was pretty bang on. I just took it and extended it for dual cans. Let's walk through the transformation


Before

I had a single can attached to a piece of steel that was bent like an L and wedged under the battery. Left room to add a second can. However being steel, it started rusting so I had to do something else.

Entire engine bay before

Closeup of the can. I have a one way check valve on the intake of the catch can. This was recommended by Vortech @Brian@Vortech

You can see the secondary breather hose here. one of my mates had tons of blow by gas go through here after a track day. Kinda stinks that the outlet is all the way at the front of the car.

I like taking pictures. Ended up losing track of time because I had so much fun taking pictures.

Prep

Danbo is helping me today. These are all the parts laid out. Some of the screws and extra hose are missing from this picture

The U-bolts @neutron256 recommended. Not pictured are the nylon lock nuts that come with them. These will slip over the triangle chassis stiffener.

Piece of aluminium that the catch can bracket attaches to.

Cans installed. Note the dipstick is different. Radium changed the design slightly. No more flat mesh filters. The new can has a metal dish scrubber like material (the name eludes me right now)

20130607-RadiumCatchCanNumber2-081 by VictorN07, on Flickr

Fittings installed. The can on the left is my old can I repurposed for the secondary breather. It has 1/2" fittings (-8AN). The can on the right is my new can. The input is a 3/8" fitting (-6AN) and the output is 1/2" (-8AN).
Due to the proximity to the battery I ended up swapping the 90 degree input barb from the secondary breather can to the output of the PCV can.
You'll see this later.

Installed

I actually like how clean this came out. Kind of looks like a pretty girls flowing hair.

You can see the final configuration of the barbs. The secondary can uses only straight barbs. The primary can (PCV) uses 90 degree barbs. The perfectionist in me says to get 90 degree barbs for the second can but at 26 quid each it gets pricey really quick. It works so I think i'll leave it for a while.

Backside of the can. I can reach in with both hands to unscrew the cans without undoing the bracket so it is still easy to maintain.

Another angle of the setup

Thanks for viewing

Great job as always Victor. Looking forward to checking it out in person. I need to rearrange some stuff inside the bay and will consider a 2nd can especially before taking it to another road course.

I can't imagine how much oil blow by it would see under hard driving.
So far looks like this is an important addition, namely with running 0w20 the oil mist is like water.

Better yet would you want this blow by oil back in the crank case like how Crawford does it?

Wow.really?that much oil already?I made consider one of that then.

@Dezoris

Any chance of a pnp kit from a vendor or from Radium directly?

Just an update, Radium will have a kit and more in December sometime. Assuming there is no snag in production.

[whataboutbob]

Catch can is on my short list. Thanks for the additional info as I am looking to this vendor for my part.

It seems they are looking for a car to develop the kit.

So for those of us with a FI option that removes the stock intake box/tubing where would you put the line from the outlet of the catch can? Would it go on the hot or cold side of the turbo? @Dezoris

Hot side pre-intercooler/pre-maf.

[Brick]

That's what I figured but wanted to make sure, do you need a check valve to keep the catch can from getting pressurized?
