It seems there is going to be a proposal to enlarge the oil sump. The committee is going to write a proposal and sent it on to the CRB. You can sent in your comments to crb@scca.com

Why? So we can spill more oil?

Yes, for some strange reason engines back east don't last too long.

The Fasrac out today has approved the sump extension for 1/1/10. There some tracks around the country that demand a lot more oil than ours out here. RA on a cold morning comes to mind so does Blackhawk Farms.

This sump proposal has some benefits; it also has a few negatives.
Benefits: better (BUT NOT GUARANTEED) oil supply. There are a couple of off-the-shelf units out there right now (CB Performance has a 1.5 qt unit that fits well, and also 2 and 4 qt versions; perhaps there are others).
Negatives: There is no limit to the size of the sump except that it can't extend below the chassis; SO, my new sump will be big enough to hold ALL my oil which will seriously reduce internal windage of the oil interacting with the crank - ask anyone who dynos our engines and they will confirm that a lower oil level will increase the HP. This will add some weight to the car. Significant added expense for a custom sump to take advantage of the rule change. Probably more negatives that I haven't yet thought of.
I think that a limited volume sump (say 1.5 quart max.) would be the best approach. You can fabricate one or buy one inexpensively. Keep in mind that the need for the larger sump is due to less than ideal oil control inside the engine. Those steel windage trays that are readily available help but could be better, AND the pick-up tube in the case can have air leaks so you might be sucking air instead of oil during some hard cornering regardless of your sump.
My $.01.

PS: If this is approved without limitations, I will be manufacturing and selling swing pickups for the new sumps. Price is TBD.

I just got a response from Kevin Yaghoubi SCCA Technical Coordinator, Club Racing. His words " I do not know who stirred this up again, but it is not happening. Please tell your fellow competitors "

I just got another e-mail. He apologizes, he mistakenly thought it was about dry sump instead of a sump extension.
