Lightened, knife edged crankshaft [Merged 6-8]

[Defiant]

I want more information from defiant on this. You say it won't hit the oil, or slap it on its down turn, but how so? The oil isn't that deep in the pan when running, since the oil is out doing it's business around the engine... So the blades would exit the oil pool and then have to reenter it again.. I would think anyways, if I'm picturing where the crank sits, and guessing how deep the oil would be anyways.. Now I know your leary of a lot of things that go on (many for good reason), but I would like to know more about this, if you have facts to post up.

See how big that sump is? See how small it makes a gallon jug of milk look? Add a quart to that jug, and there's your oil capacity. Crankshafts haven't much run in the pan oil since Model A Fords moved away from dipper-and-splash lubrication of the bottom end.
A full system of oil in a car's engine might be a pint. You'll have more finding its way down from the underside of the cam cover, the sides of the block, undersides of the piston crowns, cylinder walls, and divots in the head than is in the oiling system.
Knifing a crank is doing more to streamline its passage through the air in the crankcase than it is to help it through whatever oil might be in its vicinity. The bottom-end bearings are continually having oil pumped from them and are leaking it, so the crank and rod big-ends are going to be rain-birding the inside of the crankcase all the time. Most will be getting flung off from the longest parts of the counterweights.
