BMS oil catch can baffle

Mike@N54Tuning.com · 11-15-2011, 06:34 AM

Hey guys,

One of the areas you need to balance when doing catch can design is the internal baffle. It can't be too restrictive or you'll have crankcase pressure problems yet still has to create enough turbulence to allow oil to condense out or you won't catch anything. I know many catch can makers hide their baffles away inside a welded can but on the BMS oil catch can the baffle is right there for you to see. It's even removable. I think they really hit the nail on the head with this new two stage internal baffle. It's a very free flowing design yet still provides excellent oil/vapor separation.

Waiting for Big Tom's review. Looks fantastic.

cn555ic · 11-15-2011, 07:02 AM

When I get the unit I am going to throw in the can some steel wool to absorb the oil. Added measure to help retain the trapped oil even further. Best design to date

enrita · 11-15-2011, 07:05 AM

yeah this catch can looks great. I agree with beeing best design so far.

Zasquatch · 11-15-2011, 07:08 AM

What size are those hoses? And is there any concern with that 180 degree bend on the outlet?

I agree though, best looking design I've seen so far. Nice job.

Is it out for purchase yet? Has it been tested so far?

very nice...

Joshboody · 11-15-2011, 09:26 AM

hey mike, you are still keeping the stock on boost (external) check valve hose right?

5soko · 11-15-2011, 09:36 AM

This is what i love about Terry and Mike.. They listen to the people and go and make products for us, and work with us to design and re-design what is needed.
Great work guys!

InsaneDriver · 11-15-2011, 09:52 AM

I think everyone is going to wait Big Tom's review and then buy it.

Big Tom WE TRUST YOU!

Syndicategt · 11-15-2011, 10:35 AM

Awaiting on this patiently. I'm also interested in seeing pressure tests, which is important for guys running upgraded turbos.

stealth-twntrbo · 11-15-2011, 10:57 AM

i'm getting one of these finally one thats not $400, looks very nice!

Jeff@TopGearSolutions · 11-15-2011, 01:07 PM

I may snag one of these myself

Big Tom · 11-15-2011, 03:13 PM

I'm really, really impressed about the design and finish!

The guy behind that CNC machine really knows his job.

Can't wait to get mine.

What do I do if I decide that one of these may be helpful but I changed the strut bar with an M3 strut bar ?

I'm keen to see the test result as well and may buy one if it proves to work well. The price is definitely right for a complete kit. BMS understands the importance of attractive pricing, which is rare for BMW accessories...

The location appears to be service unfriendly but it should be no problem to extend the hoses some except for the increased risk for freezing. There are more than a few frozen crank case vents with engine damages on BMW's with external ventilation piping. So it may be a good idea to keep the hoses short as they are, or insulate the external parts on cars that are used in cold climate. Especially for vehicles that are used for short distance commuting where more and more water is condensed in the oil.

Or perhaps I'll wait for the improved version, which will have options for dipstick and/or a switched output for service indication

bahn stormer · 11-15-2011, 06:27 PM

Looks like a great design, but I won't buy one without seeing a crankcase pressure test.

cn555ic · 11-15-2011, 06:38 PM

Added my name on the list. One request is mine comes in polished finish to keep with my engine theme. This will be my FIRST BMS item on my car!

If it can't be done I will be pissed Mike so make it happen in polish Cnc for me
