My first engine had baffled pan and don't know what else (I bought it as a built race car with a reliable history.)
I blew the engine the first race weekend after a long left hand carousel holding >1G the whole time.
When I replaced the engine, I reinstalled the baffled pan and had DD Performance port the oil passages on the timing cover and install Toda oil pump. I also installed data acquisition at the same time to record oil pressure.
Took the car to another local track, and even with the above mods, the oil pressure was still going nuts in a few turns- particularly hard lefts after a braking zone.
Sooo I installed a 2 qt Accusump as well. That has improved the situation and the oil pressures are higher in the turns but still ugly.
The issue is that these engines are flat and wide. under hard cornering, all the oil schleps to the outside head and valve cover and doesn't drain back into the pan before the oil pump empties the sump. voila. no oil, spun bearings. done fast enough, it doesn't just spin the bearing but breaks a rod and the rod then turns into an axe and chops the block into pieces.
I'm working on some other ideas on the oiling and will post about them if they work.
