The hi rpm will tend to hold oil in the upper part of the engine and lower the oil level in the pan. The G's will push oil to the right side of the oil sump and away from the pickup.

This may seem picky but if an aftermarket oil pan will prevent engine damage in this situation, I want one.

Actually, on a hard right (I think), you will almost definitely see a loss of fueling, even at half a tank -- it's been documented numerous times on here.

Regarding oil, I don't think that has been a problem relevant to the oil pick up on the track -- revving over 7700 RPM has been associated with some issues, but not g's, at least to the best of my knowledge.

The primary oil problems that seem to crop up on the track are all due to oil temp (ECU imposes "limp mode" at ~260* F).

You might try posting/searching through the track forum, but I'm pretty sure no one has managed to blow a motor due to oil starvation (well, other than those who were unlucky enough to get oil burning motors...).

As to a dry sump, I only person I know of one person who did that, and it was to deal with safe rev levels, not g-related oil starve.
