Oil System Differences: Wet vs. Dry Sump

Wet Sump Oil SystemThe use of a wet or dry sump oil system is usually based on the level of competition and a racer’s budget.  A wet sump system is based off the original oiling system and can be enhanced with aftermarket parts.  A dry sump system is meant for the top levels of racing where maximum power and control are necessary.

Wet vs. Dry Oil Systems

Dry Sump Oil SystemWet sump systems store the oil in the pan but a dry sump system stores it in a separate tank and pumps the pan clean leaving it essentially “dry”. The usual set up for a dry sup system uses all but one of the stages to scavenge oil from the pan and the last stage is used to pump oil from the motor.  The primary advantage of a dry sump system is that it makes more power by creating extra crankcase vacuum with the dry sump pump, which improves ring seal, and by keeping the rotating assembly free of windage allowing it to spin freely.  It also has increased capacity, remote coolers, and  adjustable and consistent oil pressure.  The lack of oil in the pan also allows for it to be shallower which improves weight distribution and handling.
