More complex dry-sump systems may scavenge oil from other areas where oil may pool, such as in the valvetrain. Power can be further increased if the dry-sump system is designed to create a vacuum inside the crankcase, which reduces air drag (or 'windage') on moving parts as well. Improved pump efficiency to maintain oil supply to the engine.
Dry sumps also allow for more power because they reduce the amount of windage, oil sloshing up into the rotating assembly, and the vacuum from the scavenge pump improves ring seal. [10] Dry sumps are more popular in racing applications because of the improved power and reduced oil sloshing that would otherwise reduce oil pressure.

Cosworth also integrates an advanced dry-sump with an extra internal scavenge pump to distribute the oil. While a dry-sump system requires more oil (more weight), a dry-sump will keep the engine lubricated under hard cornering unlike a wet-sump system.
Often though, oil in the sump can slosh during hard cornering, starving the oil pump. For these reasons, racing motorcycles and piston aircraft engines are "dry sumped" using scavenge pumps and a swirl tank to separate oil from air, which is also sucked up by the pumps. [2] A sump can also be found in an aquarium, mainly a reef system.
