Donkervoort P24 RS Engine Uses Dry-Sump and 3D-Printed Manifolds for Optimal Airflow

Donkervoort engineers lowered the P24 RS's engine by 6 centimeters using a dry-sump lubrication system, which not only allowed for a flat floor design but also lowered the center of gravity for sharper handling and better balance. The dry-sump system is essential because the car generates extreme lateral forces that would cause a conventional wet-sump setup to fail under braking, acceleration, or hard cornering.

To ensure reliable oil flow in all conditions, the company designed a dual-pump layout with an internal pressure pump and an external suction pump. Much of the plumbing is integrated into a 3D-printed housing, reducing weight, clutter, and complexity.

On the exhaust side, Donkervoort uses 3D-printed stainless-steel manifolds shaped to match custom Van der Lee turbochargers, resulting in sharper throttle response, lower temperatures, and a weight saving of 6 kilograms compared to cast alternatives. The intake manifold is made from carbon fiber and aluminum, further reducing weight and improving performance.
