FE oil pan

A little off topic, but the principles apply..

Even the new Z06s are losing engines w/the hard core trackies too, in spite of the dry sump. It seems that at or above 1.3 Gs there's a large oil surge in the dry sump reservoir, enough to uncover the pump suction port. It also seems the new LS9 (ZR1) and the 09 Z06 will have a redesigned and larger dry sump tank that will support any lateral Gs that the car's capable of..

The pan design and spring loaded door baffling is the only way to control oil pump suction in a wet sump system. The windage tray is solely meant to keep the splashing oil from being whipped into a froth, possibly aerating the oil ( loss of oil suction their too) and creating parasitic losses alike. A fast rotating crank actually creates air turbulence (hence "wind"age tray). The windage tray provides a bourndary for the air turbulence. The windage tray is either a screen and/or baffling. It will pass oil quick enough so as not to hinder oil drain-back to the pan, a bad thing too. On a long sweeper, or short one for that matter, if the oil starts to climb the pan's side-wall(s) the windage tray will do absolutely nothing to stop it, as it is intended to pass oil.
