4. No windage problems in pan as no oil sitting in crankcase
In addition to lower center of mass due to a lower engine, there are a few other advantages of a dry sump. Dry sump systems give you the ability to adjust oil pressure, and are easier to add more oil coolers. The primary performance advantage is because of a decrease in windage losses. Basically, without as much oil in the oil pan, the rotating assembly is not sitting in a pool of oil and spin more freely. Also, a dry sump system creates extra crankcase vacuum which increases ring seal.
A dry sump system will cost a lot on these motors and unless you're building a dedicated high-dollar track car, i'm not sure if the investment is worth it. Here's the kit from Turner:
