So if I don't kick out but elongate the sump forward I can add nearly three quarts of capacity. I'll have to bring the pickup forward to the new center but I was planning on modifying that anyway and the weird ass way it's made moving the screen forward is dangerously easy. The question left is one of is it better to elongate than widen and I suppose that's dependent upon the way the car is driven.
Moving the sump and pickup to the middle seems like a no brainer, in theory the oil drains back evenly front to back so the most consistent way to keep the sump full is to have it in the middle. From there though I'm not sure. Will there be more consistently high lateral or longitudinal accelerations and does the difference even matter... Also I've drawn an inclined front to the sump, should that be flat to minimalize the amount of oil trying to climb out of the sump under braking. There will clearly be a baffle to try and control that. Can the skinny bias ply tires generate enough G force in any direction to make all this anything more than a waste of time?
I have no answers to these questions and more.
