Basics of Dry Sump Tanks
A dry sump tank is an essential component in a dry sump oil system, commonly used in high-performance and racing vehicles. Unlike a traditional wet sump system, where the oil is stored in the oil pan beneath the engine, a dry sump system uses a separate tank to store the engine oil. This provides several advantages, including a lower center of gravity, improved oil control, and increased engine reliability under high g-forces.
Function and Operation
Basics of the dry sump tank’s function and operation involve the extraction, storage, and distribution of engine oil. The system operates by using one or more scavenge pumps to extract oil from the engine and transfer it to the external tank. This process helps prevent oil starvation during high-speed cornering or acceleration, where traditional wet sump systems may encounter oil slosh and pickup issues. The tank’s design allows for effective de-aeration and separation of air and froth from the oil, ensuring consistently high oil quality and lubrication performance.
Components and Design
Functioning at the heart of the dry sump system, the tank’s design comprises various components such as inlet and outlet ports, baffles, and oil level indicators. The tank’s size and shape play a crucial role in the overall system performance and are determined by factors such as the engine’s oil capacity, operating conditions, and vehicle layout. The tank’s construction material, often aluminum or steel, is chosen to withstand the high temperatures and pressures experienced within the system, ensuring durability and longevity.
Operation of the tank relies on the efficiency of its internal baffling and reservoir volume to ensure proper oil scavenging and storage. The design of the tank and its components must be carefully considered to maintain optimal oil pressure, prevent aeration, and facilitate efficient oil recirculation. Additionally, the tank’s positioning within the vehicle and the routing of oil lines are critical factors in maximizing the system’s performance and reliability, especially under high-speed and high-g force conditions.
Factors Influencing Tank Sizing
Obviously, there are several factors that need to be taken into consideration when sizing a dry sump tank for a particular application. These factors can vary depending on the engine’s size and type, the vehicle’s application and usage, as well as the pump capacity and type. By understanding the interplay of these factors, you can ensure that the dry sump tank is sized appropriately for the specific needs of your setup.

This comprehensive approach will help in optimizing the performance and reliability of the dry sump system.
Engine Size and Type
An important factor in determining the size of the dry sump tank is the engine’s size and type. A larger engine with a higher displacement will typically require a larger tank to accommodate the increased oil volume needed to properly lubricate and cool the engine components. Additionally, the type of engine, whether it’s naturally aspirated, turbocharged, or supercharged, will also impact the oiling requirements and thus the tank sizing.
Vehicle Application and Usage
Engine power output, vehicle weight, and usage will heavily influence the oiling requirements and subsequently the dry sump tank size. An engine used for endurance racing will have different oiling needs compared to an engine used for drag racing, for example. It’s important to consider the vehicle’s application and usage to ensure the dry sump system is capable of meeting the demands placed on it by the specific driving conditions and performance goals.
Vehicle weight, road conditions, and acceleration characteristics are all factors that will determine the size of the dry sump tank needed to maintain optimal oil pressure and prevent oil starvation.
Pump Capacity and Type
On the pump side, the capacity and type of the oil pump should also be taken into account when sizing the dry sump tank. The pump’s capacity will dictate the rate at which oil is scavenged from the engine, and the type of pump (external or internal) will impact the overall oiling system design and tank sizing requirements.
Influencing factors such as pump efficiency and scavenging ability will need to be considered when determining the appropriate size of the tank in relation to the pump’s capabilities, ensuring a well-balanced and efficient oiling system.
Calculating Tank Size Requirements
