I promised you new stuff...so here it is

The Go Fast Lab and TC Design are happy to announce the only commercially available trap door oil pan for the S2000!

The OEM pan allows oil to move away from the oil pump pickup location during sustained high-G situations like those experienced on high speed sweepers or banked turns. When this happens, the motor can momentarily lose oil pressure and when it happens repeatedly or for a sustained period then the result is usually spun bearings and an epxensive repair for a blown motor. Not good.

This pan is designed to reduce the possibility of high-G induced oil starvation in the S2000 motor. It bolts right up to the motor without additional modifications and the welded-in baffle fits tight up against the factory oil windage tray. It has three trap doors that help control oil movement during high-G turns. The baffles and trap doors work by letting oil flow unimpeded during normal operation to the pump pickup but under high lateral G loads, the doors close to prevent oil from escaping the pickup location.

The pan is $425 shipped to the continental US and Canada.

You forgot one thing: the introductory sale price -- $250 shipped!!
j/k

More seriously, was any real-world testing (e.g. Ry's car) done on the piece? Any concerns about the trap-door mechanisms over the course of years of use? What happens to overall oil flow if high lateral g's are sustained for a VERY long time (a minute or more)?

Also, what's the difference between the trap-door design and simple baffled designs? Should one theoretically work "better"?

 

Yes, $550 shipped for you

For very long periods of high-g loading prudence dictates that you should still look into pressurizing systems like an accusump or dry-sump system. In that case, the issue would be the inability of oil to drain back to the center of the pan after travelling through the motor since it might be flung to the "outside" or closed side of the pan and not to the unloaded or open trap door. I hope this makes sense?

The trap door pan is a proven solution, as it actually greatly deters oil movement out of the sump area by using a physical barrier that closes using the simple momentum of the oil. The doors aren't spring loaded, so they don't impede flow into the sump at any time. Simple baffles can't be closed all around the sump or oil would never be able to drain into the bottom; they work by trying to keep oil in by using convoluted paths but they can't be sealed completely. For that reason the trap doors are much more effective than simple baffles.

No concerns about the longevity of the doors or hinges really. They're not spring loaded so the only load on the hinge is the (really negligible) weight of the door and clearly the whole mechanism will be well lubricated at all times

 

Any value in this if the car already has an accusump?

 

John:

I ran a prototype for a while on my car and tested the final version (what we're selling) on my car at the last SV event. I kept very close eye on my oil pressure gauges and had no problems.

Mike:
Yes absolutely. I run them both since they do different things. The pan will allow you to go much farther into the corner (think banking at like cal speedway) before you actually start to starve the pump. But if you sustain enuf g's long enuf the accusump becomes your next line of defense as it will help maintain the pressure once you've pumped all the oil out of the baffled section of the pan. If it were me I would always use both.

hmm, some of the local autoX designeres seem to favor throwing in really LARGE skidpads (boring). When I say large, think 15-20 seconds to get around. I never liked the thought of my oil getting pulled to one side for that long.

Are the external demensions the same (will it interfere with an X-brace)?

 

Its an OEM pan, there are no differences on the outside.

 

is this any different or better than the Mugen baffled oil pan?

 

Well, yeah, Mugen is just baffled. These actually have trap doors that work.

Of course we dont have the cool Moogen stickers but if you want to feel like you bought the Moogen one, I'll spray paint it gold and charge you double

Yes absolutely.
