Default Oiling System Feeler: Racecars Only... Oil Control Valve

Attention! This is not a product that would EVER be needed on a street car.

It is a product for racecars, specifically boxer engine cars, able sustain +1.5Gs consistently. If you are unsure if you have a 'racecar' ask yourself some simple questions. Does my car have a true safety cage? Does my car run race slicks? Do I have a competition license? If you do not answer yes to all 3, this product would very likely be utterly useless for you. If you did answer yes to all 3 please read on.

The Subaru boxer platform can have issues with oil surging in the heads. It can be related to the level of performance, driving style, track conditions and so on. This burden is often overwhelming to the PCV's A/O separator or Catch Can system causing them to fill. Filling an A/O separator or catch can causes oil levels to drop increasing the potential for oil starvation. Another condition is if a catch can fills, and overflows onto a hot engine and/or exhaust system creating a fire potential, which has been known you happen.

This product feeler is for a product that prevents oil flow out of the valve cover ports based on the lateral forces placed on the car. This design has been successfully used in aerobatic aircraft for years and we have adapted the design to be suitable for lateral loading vs inverted flight (which rarely happens in cars). Under straight line acceleration, braking and moderate cornering the PCV vents work just as they normally would; letting blowby gasses vent from all ports. Under severe lateral loads the port from the surging head (facing the outside of a corner) is closed, not allowing oil to pass into the A/O or catch can setup. The balance ports and remaining head and crankcase ports still operate as normal. This has no negative effect on the engine or engine performance, while assuring blowby gasses ONLY are permitted through the PCVs ports.

This product design has been discussed for years and now we are putting rubber to the road. Before doing so we're looking for feedback from the communities to gauge interest, and in turn, production levels.

Please feel free to voice your thoughts, concerns or questions. We'll do our best to answer everything as best we can.

Thanks!

there could be a market for that, oil comes flying out of some catch can systems on the track.

Not really. In Auto-X we really don't see the same combination of forces and RPM that are seen in road course racing.

In Auto-X when oil is seen in the venting system it is due to sloshing, not surging. This can be solved by changing plumbing routing. A cheap and easy fix

Not sure if the 1.5 G's applies to rally cars, but as slideways as we get, I would assume this system would work for us as well. And I definitely would be in line for this type of system.
Question that just popped up in my head, since we transit in between stages for up to 70 miles, would your system have any effect on "normal" driving.

Yes, under normal driving it operates just as normal, all 3 ports venting. The ONLY time the valves come into play is under severe cornering.

Would the valves close based on inertia? Ie, would only the valve on the head that is oriented to the outside of the corner close? I see no reason to close both valves at the same time.

The port going to the head facing the outside of a corner is close only, not both.

Could this product be helpful with oil control to the point that it might lessen the need for a dry sump setup? I'm think in terms of my 818R.

Depends on how you determine the need for a dry sump. This product will prevent oil from surging out of the heads and into the PCV system.

just trying to get my head around this,
where r these ports fitted, do they stop oil pooling in the head or stop the oil in the heads from entering catch cans??

Stops the oil from entering the can, or A/O separator, via the head ports.

So is this going to be something similar to an inverted flight breather setup?

^ No, this does not use floats. Thought about going that route, but I'm not convinced it's the better method with intermittent loading at the threshold of activation.
