Interest in an improved oil pan which should help reduce bearing failures?

Any interest in a new oil pan design? A new pan could be designed to help reduce windage problems and foaming problems which contribute to the infamous #2 rod bearing failures (see this thread if you need info on this problem).
I've been in contact with a few companies who design oil pans for race cars. Several have offered to make an improved aftermarket pan which can take care of some of the most severe windage problems and potentially increase the volume a bit.
These are the basic specs (subject to change depending on price and feasability):
* Most importantly it will have a kick out on the right hand side to allow the oil returning from the head to escape the crank and return to the sump without following the crank around 270 degrees and foaming up. A bit like the kick out on this Moroso pan where the company logo is. This cick-out should work in conjunction with a scraper.

* Built in baflfing system with one-way ports to prevent oil from being sloshed onto the crank when braking, turning and accelereating.
* Integrated crank scrapers like the stock pan, but tighter (possibly teflon blades?).
* Much improved integrated windage tray with proper louvres to cut down on windage. Becuase the tray is installed in the pan it will not be necassary to split the block and ntefere with its integrity and the bearing clearances to install the windage tray. .
* Integrated gasket retainers to stop the gasket from pushing out.
Here's a rough sketch of the basic ideas. There will also be baffles in the sump itself.

The windage tray will sit on top of the baffles and the baffles will be welded to the tray to give it rigidity and to ease assembly. The windage tray will be bolted to threaded inserts in the pan.
The diamond shape minimizes slosh and, together with the two outside perpendicular baffles, makes the trap doors more efficient as the oil outside the diamond shape will be forced into the centre of the diamond by acceleration, deceleration and cornering forces.

To get this moving we need to get 10-15 people together in a group buy.
Please sign up here if you are intersted in such a pan. For now the list will be to judge interest only. If there is enough solid interest I will make a bindig list once the design is finalized.

Make sure your pan people are fully aware that the engine leans over and the pan rails are not perpendicular to the ground. That issue will affect the pan design.
I hope you get some interest in this. A good wet sump pan for the 944 is sorely needed. If you don't get the interest you need, PM me. I have a pan you may want to test.

I just got a few replies from some manufacturers but no prices yet. It will obviously cost a bit, but the improvements should make it worth the cost.
A really good improvement would be to find a standard type oil pan gasket and make the pan deeper by the same amount instead. It would minimize the leaking problems and stop the gasket bulging out once and for all. It may be difficult to find a suitable gasket though.

I need some solid interest in this before I go ahead with all that work though.

Thanks for offering to help admiralkhole. Do you mean to make a prototype? If not one or two pans will be of a great help to those who get them. My goal is really to generate some interest and possibly make this more widespread. Such a pan should be very popular with the racing crowd provided the regulations will allow it, or can be changed to allow it.

A prototype could be useful. I'll let you know if we need one.
I hope this will continue to generate interest for a while. If it does this may actually come to fruition which would be great.
