Why is a dry sump system commonly used in high-performance vehicles?

A dry sump system is commonly used in high-performance vehicles primarily to maintain oil pressure at high G-forces. In such vehicles, rapid changes in direction, acceleration, and braking can cause oil to move away from the oil pump pickup, leading to oil starvation and potential engine damage. The dry sump system addresses this issue by using multiple oil reservoirs and a series of pumps to ensure that oil is always available to the engine, regardless of the vehicle's orientation or movement.

This system also allows for a lower engine placement, which can improve the vehicle's center of gravity. Overall, the design helps maintain consistent oil pressure and lubrication efficiency under extreme driving conditions. Therefore, its key advantage lies in enhancing engine reliability during high-performance operation, especially in motorsports where high G-forces are common.
