Considering the crank is flinging oil the full 360 deg of rotation, even with a scraper its still throwing oil up on the pistons and pins...Mike's deflectors (and the IJ scraper) just direct drainback from the heads into the bottom of the pan- and hide that drainhole from direct windage off the crank. There is still plenty of oil blowing out between the rods and crank to lube the pistons and pins....
The pic Kevin posted of the Ford block and pan show the drainback path to be hidden from the crank completely- this is what we need to achieve.
Regardless of MK's statistical anomaly of engine life, Louie's video clearly proves aeration and windage are a problem... How MK gets away with, I don't know. For us mere mortals, the answer is to do what we can to prevent it.
My car has about 20 hrs of track time on it, WITH Mobil 1 (eek!) and hasn't had a problem----yet. But if I were to rebuild it, I certainly would make some effort to contain the drainback and windage... Greg Brown, Mike Simard, seem to have some things that work.
