Air Oil Separator Teaser Pictures
 

Been working on a catch can set-up for these cars for the better part of this year and finally think we have a design and mounting more or less nailed down. Figured we would share some photos and see what you guys think about it.

Everything is in the prototype phase, so bare aluminum and welded brackets. Finished product will likely be all black anodized, the bracket will be bent aluminum and also anodized black, or that is the plan.

What separates this Air Oil Separator (AOS) from others is that it utilizes a filter media that is specifically designed to separate water and oil from air down to 5 microns! 5 microns is 0.00019". The filter media is still capable of flowing approximately 50 SCFM at 100 psi, so no restriction there. Basically these ensure that no oil will get from the crankcase to the intake manifold or the intake pipe.

These are photos of the first prototype in design phase and prototype billet pieces.

This is the second design. It features dual filters, a machined baffle, and will not need any welding. We came up with this design to ensure all oil and water get filtered out and to reduce overall costs of the can. Yes it is better and will be cheaper :drool:.

Current mounting is shown above. The little intake manifold cover can be used with both can placements and the bracket. The bracket will look a lot nicer and cleaner when finalized as well.

Thanks!

Looks good, got an ETA for those in the market?

How easy is it to access the drain port? What do you think about including something like a Fumoto drain valve with a nipple instead of just a drain plug? Might be easier and cleaner to drain it that way. Or make the threads the same as the oil pan drain plug, so people could make that change on their own.

Drain port is easy to access. It is a internal wrenching hex drain with an o-ring seal (-4 AN to be exact) and can be unscrewed with a 3/16 hex bit. We can look into utilizing a coolant drain petcock like this if that is what more people are interested in having. Our ETA is a month or two out.

How easy is it to catch the oil as it comes out of the AOS? I was thinking that something you could connect a hose to might make it quicker and cleaner to drain. Just an idea.

The filter media can it eventually get plugged / dirty and present any issues in this design? I like the fact of being able to see what's been collected vs just going back to crankcase and placement looks decent to.

Can the weld on fittings be replaced by non weld on ones?

Thanks for the idea. We will look into it or maybe have it as an option. We try to consider cost in everything we design and build as we are constantly striving to bring you guys the most potent products for the lowest price.

I assume that eventually the filter media could clog and go bad, but I have no way of telling when. It would have to be tens of thousands of miles. The AOS is fully rebuildable and easily disassembled/reassembled, so this could be checked every 30k if it is a concern.

I used a system with this same media device in it on my Evo IX for 20k, it worked flawlessly the entire time and the media never changed really. I was very happy to not be shoving the oil back into the intake manifold as well.

You will have to clarify your question as I don't exactly know what you're asking. The newest catch can that has been designed does not require any welding at all.

Apologies, I couldn't tell just by your prototypes then the drawings that indicates this since there doesn't appear to be any threads for the fittings to screw on to.

Drain petcock would be a plus for me.

I'm surprised you didn't have a field day with that one.

^^lol
yeah, I thought about it :)

His ambition in life was to be one for somebody from the first time he heard the term. Imagine his disappointment when he learned what it really meant.

$400.

I'm still not sure why these things are so expensive. It's literally about $30 worth of aluminum and fittings

Where is price even listed in here? Obviously you don't have machined parts made much if you think it is only $30. I don't even know if you could get the cost down to $30 with making thousands of these.

It was more from past experiences in regards to the price.

And yes, that is a point. Sorry, i look at raw materials over machining cost.

And labor, shop rent, insurance, tax, development costs, interest on any loans, heating/cooling and lighting, water and electricity.

I used to have a pet cock. I would wake up in the morning with my cock snuggled up close to me, I could stroke it with out any effort. Sometimes it would catch a cold and I would have to put a tissue over its mouth to catch all the spit. We would go out for walks. It looked so cute with a tiny a leash around my cock and if I saw a hot looking woman my cock and I would acknowledge her. Me, by losing awareness of my surroundings and my cock seeming to draw itself up. Seeing a cute chick made me nervous because I was scared I would say the wrong thing and I'm not a chicken pedophile. When the pressure became too much I would open my pet cock to let all the build-up out. I love my cock but ownership is sometimes a bit hard.

Their are threads, threads do not appear in CAD all that well :).

Noted, we can definitely do this if this is what most people are interested in. We thought the O-Ring seal is a nicer, cleaner, and more positive way of sealing a bung but we can go NPT and put a drain petcock in there, no problem.

The $400 price tag isn't even close for one. We are looking at being able to sell these through a vendor at ~$400-$450 for a pair. $30 worth of aluminum maybe but the fittings are custom machined as well. I would love for you to find us a machinist who will do the work for next to nothing but I can't.
Please PM me if you know of someone though :party0030:.

We don't even factor in development costs, R&D/Prototype costs, sourcing time, packaging, etc. when giving final pricing either. We truly are dedicated to giving you guys high quality products for a reasonable price. If the price is too much, their are plenty of other catch cans out there.

You wouldn't even need to include the valve. Just make the drain threads the same as the oil drain plug. People could swap the valve in on their own if they wanted to. That's the exact same Fumoto drain valve that I just installed in my oil pan, an F-108n.

I like this idea.

So the weld on the catch can is final then?

No those are prototypes only for testing purposes. FT86 Speed Factory will be running two race events to test the ability of the can. The newest design, attached below, is the design we will be going with as it is more refined then the first prototype.

Cool cool, got confused as those other photos look like production model shots.
I am definitely in for black ones at the current pricing as other manufacturers have fitting issues with RHD, will the dual can setup be fine for RHD?

Can you send me a photo of your engine bay via PM or e-mail? Everything is contained within the strut bars so I don't see why they wouldn't work. A picture should verify this though :).

Would you mind showing me/us a pic of the filter media? Understand if you not want to.

In the event a user is looking at this option with FI in mind I'll ask if this can is in fact capturing from two points or simply the PCV side? Sorry if silly question trying to fully understand this design...under NA applications I understand unless pulling hard and tracking there is little need or value to catch cans to begin with just want to know that this would fully cover all needs when FI.

Also any thought to powder coated options, ie: matte black??

Thx

@s2d4, the AOS bracket attaches to the same points that the wire harness bracket attaches to. If you're willing to move that and zip tie it elsewhere, the can should work for you as well.

Sure, I'll try to remember to snap a picture tomorrow. It looks eerily similar to the CAD model :thumbsup:.

This can works with NA and FI application. If you think NA applications don't need it, I would argue that they do. I've only driven a few hundred miles and I already have an oily film at the bottom. I fully expect to see quite a bit of oil come out the next time I change the oil. I already ran a "dumbed down" version of this and it collected 2 ounces in 2k miles.

Each and every can is tested to 40 psi and then submerged to ensure leak free vacuum/boost application.

We were planning on anodizing these black.

idea instead of the pet cock, can you include an option for the fumoto quick valve? It would make it so we wouldnt need to remove the catch can at that time

I will look into it. Do they make any sizes smaller than a humongous m16? I'm sure they do, just have to do some research.

@Captain Snooze here is a quick picture of the filter. It is pictured in FT86 Speed Factory's photos as well.

Ahhhh! There it is. Hidden in plain sight. Seriously, I spent ages looking for something that was right in front of me.

They make an m10 that seems pretty tiny.

As well as a stack of m12's in various thread pitches. Here's their list of valves.

edit: You could also do the m30 and market it as "Oil drain valve with catch can accessory!"

That's perfect. Jeremy at FT86SpeedFactory is sending me a part that I can draw up in CAD and then see how it will work with everything.

Definitely interested.

I like it. Definitely interested. Got any picture with the dual set up?

Currently no. I gave my other one (only prototyped 2, they were $$$$) to FT-86 Speed Factory for testing.

Thanks,
Eric

Attached is a photo of the results after 300-500 miles. The filter has oil residue on it because of the testing I was doing to it before I put it on the car. I tested it via a shop-vac sucking 10 oz of oil up through the unit to verify oil did not come out the tube, which it passed but oil did get on the filter element.

Looks good. Got ours mounted and ready for some heavy track testing as we gear up for UTCC in July. :)
