Dry Sump System

Unlike a wet sump system where oil is stored in the sump, a
dry sump oiling system stores oil in a separate tank, leaving
the sump essentially 'dry'.
Two internally-mounted pumps, are used to 'scavenge' (1)
oil and deliver it to the storage tank, and then deliver (2) the
oil through the engine.

The primary advantage of a dry sump system is its ability to
make more power. With very little oil in the sump, the
rotating assembly is not burdened with the weight of excess
oil (windage). The windage tray or screen which serves to
isolate sump oil from the rotating assembly, runs the full
length of the sump.This keeps the rotating assembly free of
windage and allows it to spin freely and make more power.
In addition, the extra crankcase vacuum created by the dry
sump pump helps to improve ring seal for additional power
gain.
Other advantages of a dry sump system include increased oil
capacity, more consistent oil pressure, the ability to easily
add remote coolers, and adjustable oil pressure. And
because the sump does not store oil, it can be relatively
shallow in depth to allow lower engine placement for
improved weight distribution and handling.
