Alright, pulled the oil pan out. Gonna scrub it nice and clean, and then decide how I want to go about modifying it.
Thus far, my problems with the oil pan are 2 part:
1) Not nearly enough oil kept in the lower sump. Seems like you could suck almost all the oil out of there, especially in a road racing application, and suck up air into the pump.
2) Lack of oil control.
I've been studying IJ's pics of his GroupA pan (thank you very much for those pics, btw!) and I'm leaning toward the following:
a) Kick out both sides of the sump area, increasing approx 1qt on both sides.
b) Use the stock plate keeping oil down, and weld baffles around the oil pump pickup (think of taking a pipe and splitting it into 2 hemispheres, and splitting those hemispheres into half)
My primary concern with this, is under high rpm/high G turns.
I'll have pics up later of me starting this, as well as measuring exactly the current sump capacity.
