Wet Sump Vs Dry Sump – Engine Oil Systems

What’s the difference between wet and dry sump oil systems? Wet sump systems tend to have significantly larger pans, with a single oil pump. Dry sump systems have shallower oil pans, with a separate reservoir and two (or more) oil pumps. By relocating the oil reservoir, there are several distinct advantages to a dry sump system: lower CG by using a shallower oil pan, flexible oil capacity – which can lead to improved cooling, and the ability to sustain high g corners without the lubrication system losing oil or pressure. *Original Description*
