My question would be, what works best.
And in my application I have no doubt it's the dry sump system.
There you go. F1 cars dry sump with something like 3g lateral forces at work. Smokey Yunick wrote extensively about the benefits of dry sump in NASCAR....they tried everything he said to get wet systems to work but the corner loads keep getting higher and higher. He had swivel pick ups etc but in the end the dry system was the only thing that worked for NASCAR.
There is one unique difference between sidecar racers and “normal”😉 road race bikes. Sidecar racers stay flat laterally. So when a sidecar engine gets put into a hard corner, the oil is pulled to the outside of the pan. Road race car owners (Smokey included) have gone nuts trying to overcome the occasional dry pickup problem.
As a motorcycle leans into the turns, I’d expect it pretty much eliminates any of the lateral forces of the oil in the pan that tend to starve the pickup. Being that the pickup is at the back half of the pan, the most obvious oil sloshing concern is under hard braking, shoving the oil fwd and up to the spinning crank. A well designed hinged trap door (as is so common on road race V8 car pans) mounted fwd of the pickup should help alleviate that issue.
The issues with oil aeration...I can’t even hazard a guess on that one.
Being that Rob tends to favor near stock displacement engined endurance racers, rather than huge maxed out stroker big bore engines in a sidecar, this seems to be a great initiation for a racing wet sump system.
