Dry Sump
A lubrication system in which the oil is pumped into the engine's sump under pressure and then pumped out again. This reduces the losses from the oil being churned around by the crank and big ends at the same time as allowing it to be cooled efficiently.
Other benefits are:
- Allows the crankcase to be reduced in size
- The engine can be installed lower in the chassis
- Eliminates oil starvation when the car is subjected to acceleration, braking, and cornering forces generated by a racing car.
