I emailed Radium asking for a 90° 2-piece in 0.425" and they told me the closest they have is the 0.5", which is selectable from their website. I guess they aren't making any more custom sizes.

i used this diy for my install. credit goes to dezoris and f1point4. i merely changed the mounting solution

Did anyone else course stainless steel wool type material in theirs rather then the stackable screens? It looks like Radium has switched (didn't notice this before I ordered) judging by some of the pics on their website now.

Not sure if this really matters or not, but the stackable screens seemed to be one of their selling points.

I just followed dezoris and took a few pictures for science. He's the man here.

That's how mine came, I was a bit disappointed not to get the stackable screens, but it's working great!

I assume they changed it because either it was cheaper for the same effect, or because it works better then the screens. Just mostly wanted to confirm that I'm not the only one who didn't get the screens, and let others know of the change.

Thanks for the confirmation that it's working well without the screens.

The rustoleum isn't holding up
Please don't use steel. I used it because I goofed at the store.

Well I have a prototype version installed...not completely though as I bought 2 clamps but my father who was helping modify them cut the length too short on one and it wasn't usable. I can say with only one modified clamp in the middle it's totally solid on the bar, silicone grip tape on the bar clamp pieces works great. The Radium mount is now the weakest link actually. Super easy to get to and remove the bottom of the can too with all that space between the battery and strut brace with this layout. It's fairly close to the hood, but clears fine in this position - further to the rear on the strut brace by a little over 1" is when the Radium intake fitting will make contact with the hood. I do plan on making a better version (TIG welded 1 piece upper), but this will do for now - with 2 more modified clamps added for massive overkill...

The reinforced racing rubber hose (1/2" for catch can to Intake manifold location and 3/8" for PCV valve to catch can location) was extremely hard to get on the fittings... see no need for clamps on them.

thats pretty creative. at first glance, it looks as though there isnt enough room to remove the can, but youre saying youve more than enough room. i think ive seen people drill directly into the bar. might be bad for rigidity..

thumbs up for coming up with a mounting solution!

[xwd]

My first go at attaching the can I just drilled another set of three holes in the Radium bracket and used a piece of 7/8 rubber tubing around the bar (it's 7/8) along with three 1/4" high strength zip ties. Honestly it would have worked fine, the can wasn't going anywhere but the one issue was the output port was facing the rear of the car. I didn't feel like spending the money on a 90 degree fitting to make the hose not loop around so I just changed the mounting.

I mounted my catch can just like sinigang_guy and it could not have been any easier. It is the exact same method as Dezoris showed except you don't have to bend the mounting bar, obviously. The bar is held nice and securely and doesn't grind on any of the wiring.

As a side note, I used the 3/8" 90° 2-piece fitting since Radium doesn't offer it in .425" and my 11/32" hose fit very nice and snug even without a clamp. I used a clamp anyway for peace of mind.

So I'm definitely doing this setup once I get my tax refund check. Most likely going to go ahead and buy the double can setup for future expansion. How is that holding up so far? Any added noise (rattle)? Also did you buy a specific thickness of the metal that you bent?


side note: Would it matter if I used the 8AN outlet instead of the ones listed?

As many have noted, the fittings and adapters that Radium sells with their catch cans are very expensive (they're also great quality, but still expensive). After some trial and error, I think I've worked out what would be needed to install a Radium can and not buy the fittings from Radium.

Male -10 AN to hose barb this one is a bit hard to find, this is the only model I came across. Used to connect the catch can outlet to the intake manifold.

Male -10 AN to Male -6 AN Reducer used to connect a Female -6 AN to hose barb 90 degree adapter* These two are much easier to find at various online retailers. The -6 AN size matches up well with 3/8ths hoses.

The total cost of these items at this particular vendor is $21.15 + shipping, so far they're the cheapest source of these parts, but most places will be less expensive than Radium.

Of course, you'll also need 3/8ths and 5/8ths hose (or -6AN and -10AN if you can find push-fit hoses sold in AN sizing). A hose clamp is definitely needed to secure the 5/8ths hose to the intake manifold. I would recommend using a hose clamp on all connections, just to be safe. Also optional are AN fitting O-rings. (Radium includes these)

Hopefully this can help save some money on future catch can installs!
