Wet sump or dry sump?
A Dry Sump system is preferable if the rules and budget allow a dry sump system. Some divisions only allow wet sump engines, and in that case, a Peterson External Wet Sump pump can provide externally adjustable pressure, more volume by adjusting pump speeds and more uniform timing by taking the pump drive off of the distributor. A great choice for those instances where you need to use a wet sump pump. Dry sump systems give you the ability to lower the engine in the chassis, due to a shallower pan configuration, control of windage and have a more positive supply of oil to the pump. Other advantages include: Externally adjustable oil pressure, the ability to speed up or slow down the pump, using different pulley and belt configurations, enabling the pump output to fit the need of the engine.
