As the late great Smokey Yunich said:
He also says:Stock wet-sump systems do an excellent job in street engines, but there are definite limits to what a wet-sump can do. ... we spent hundreds of hours and thousands of dollars on wet-sump research. We fooled around with all kinds of oil pump and oil pan modifications. We tested baffles, trap doors, swinging pickups and virtually everything you can imagine. Finally I came to the conculsion that the G-loads developed by a sophisticated racing chassis are so severe that a wet-sump oil system cannon adequately control the oil, and as far as I am concerned, every serious racing engine should be fitted with a dry-sump oiling system!
I think a low buck racer can slide along with a wet-sump. In fact as long as you can run with the pack without using a dry sump you will be ahead of the game. However if you start running really hard, the wet-sump will inevitably swallow a little air in the corner, and when this happens, the bearings and what was a perfectly good crankshaft will fall out of the engine faster than he can say, oh shit.
