Air Oil Separator Teaser Pictures - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

eric6 · 06-12-2014, 08:40 PM

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

.

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.

Captain Snooze · 06-13-2014, 07:33 AM

^^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
