From NASCAR to High Performance Street Applications, These Pumps Won't Leave You High and Dry. Dry sump oil systems are used on all kinds of racing applications from NASCAR, circle track, road course and Formula One racing to ProStock drag racing. Dry sump oil systems are even found in some current production applications such as the LS9, LS7 and LS3 engines in late model Corvette ZR1, Z06 and Grand Sport models. One of the main reasons why dry sump oil systems are used in these applications is to reduce the risk of oil starvation or aeration. When a race car is cornering hard or accelerating at full throttle, G-forces can push the oil inside a conventional oil pan away from the oil pickup tube. Baffles and a deeper oil pan can reduce the risk of oil starvation, but not entirely. By eliminating the oil pickup inside the oil pan entirely, a constant supply of oil can be fed to the engine by an external belt, gear or cam driven oil pump. That means a steady oil supply and consistent oil pressure under any kind of driving conditions.
