Kickout-Style Oil Pans: Performance Benefits And Unique Design

A kickout-style oil pan is designed to increase oil capacity and provide additional ground clearance. It features a kicked-out sump that moves the oil level away from the rotating assembly and a louvered windage tray that reduces oil temperature and improves oil control. The main purpose of a kickout-style oil pan is to collect oil around the pickups so it is always available to the engine and to keep the oil away from the spinning crank to save power. This type of oil pan is commonly used in racing and high-performance applications to maximize power and ensure reliable oil supply under harsh conditions.

Kickout style oil pans can increase capacity and provide additional ground clearance

Kickout-style oil pans are designed to increase oil capacity and provide additional ground clearance. They feature a "kicked-out" sump that moves the oil level away from the rotating assembly, which helps to reduce windage and improve oil control. This is especially beneficial in racing conditions, where oil starvation can quickly lead to engine failure.

The kicked-out sump design increases the oil pan's capacity without raising the oil level closer to the windage. This is advantageous because it keeps the oil away from the spinning crank, reducing power loss. Additionally, the extra oil capacity helps to resist oil overheating and dilute contamination.

The Moroso Power Kickout Series Oil Pans, for example, feature a louvered windage tray and a kicked-out sump, which not only increase capacity but also provide additional ground clearance. Their sump is fully baffled with five trap doors, ensuring an uninterrupted oil supply, even under harsh racing conditions.

Kickout-style oil pans can also improve ground clearance by moving the oil away from the rotating assembly and providing a more compact oil reservoir. This can be beneficial for vehicles with limited ground clearance or those that need to navigate uneven terrain.

In summary, kickout-style oil pans offer several advantages, including increased oil capacity, improved oil control, and additional ground clearance. These features make them a popular choice for racing and high-performance vehicles, as well as for applications where ground clearance is a concern.

They are designed to move the oil level away from the rotating assembly

Kickout-style oil pans are designed with a unique feature that sets them apart from traditional oil pans: they move the oil level away from the rotating assembly. This innovative design offers several advantages and is a popular choice for high-performance engines. By relocating the oil, the kickout design minimizes the chances of oil splashing and foaming, which can cause a loss of oil pressure and potential engine damage. This is especially beneficial for engines with aggressive camshafts and high-lift valve trains, as it ensures that the oil is where it needs to be—lubricating critical components—rather than being churned up by the rotating assembly.

The rotating assembly of an engine consists of the crankshaft and connecting rods, and it is responsible for converting the linear motion of the pistons into rotational motion to drive the vehicle. In standard oil pans, the oil level is typically close to this assembly, which can lead to issues. When the oil level is high and near the rotating assembly, the spinning crankshaft and connecting rods can come into contact with the oil, causing excessive aeration and oil splash. This results in reduced oil pressure and a potential shortage of oil reaching critical areas of the engine.

The kickout style oil pan addresses this issue by incorporating a "kickout" chamber or reservoir on one side of the pan. This chamber, positioned away from the rotating assembly, serves as the new location for the oil sump. By moving the oil level away from the crankshaft, the design significantly reduces the risk of oil aeration and splash. This is a common feature in racing applications where oil control is critical to engine performance and longevity. The kickout design ensures that the oil is directed to a specific area, providing optimal lubrication and minimizing the negative effects of oil movement within the pan.

Additionally, the kickout style offers improved oil control during acceleration, deceleration, and cornering. In a traditional oil pan, the oil can slosh back and forth, again leading to potential oil starvation or excessive oil surge. With the kickout design, the oil is directed to the sump, ensuring that the pickup tube always has oil available, regardless of the vehicle's movement. This consistent availability of oil at the pickup tube maintains proper oil pressure and ensures a continuous supply of oil to the engine's vital components.

The benefits of kickout-style oil pans are clear, and they are an essential component for optimizing engine performance and reliability. By moving the oil level away from the rotating assembly, engine builders can rest assured that oil pressure will remain stable, and lubrication will be consistent. This design showcases the innovative approaches engineers take to enhance engine performance, and it is a testament to the ongoing advancements in automotive technology. Whether on the racetrack or on city streets, kickout-style oil pans play a crucial role in maintaining the health and longevity of high-performance engines.

They can be used with or without a windage tray

A kickout-style oil pan is an oil pan with a "kickout" on one or both sides. This feature provides greater volume inside the pan while minimising its overall depth. A deep pan can be a liability as it either hangs too low in the chassis, creating the possibility of damaging the pan against the track surface, or it requires the engine to sit too high, raising the car's centre of gravity.

Kickout-style oil pans can be used with or without a windage tray. A windage tray is a physical barrier that prevents oil from getting into the rotating assembly during vehicle motion. It also allows oil coming off the crank to easily enter the sump without affecting the scavenging of oil already in the sump.

Windage is the flow of air within the crankcase. Each time a piston comes down in the cylinder bore, the air under it is pushed into the crank area, and each time the piston goes up, the air is pulled behind it. At the same time, the rotating assembly is spinning and churning the air, adding oil into the mix. The windage tray keeps the windage around the crank separate from the oil in the sump area.

While a windage tray is not necessary with a kickout-style oil pan, it can provide additional benefits in terms of oil control and engine performance. A windage tray can prevent oil from splashing back onto the crank, reducing drag and the risk of oil aeration. It also helps to maintain oil temperature and pressure by reducing the amount of oil that is whipped up and creating a heavy atmosphere in the crankcase.

They can be used for circle track racing, drag racing, off-road racing, or any performance vehicle

A kickout-style oil pan is designed with a louvered windage tray and a kicked-out sump that moves the oil level away from the rotating assembly, increases capacity, and provides additional ground clearance. They are suitable for a wide range of vehicles and motorsports, including circle track racing, drag racing, off-road racing, and any performance vehicle.

The louvered windage tray in a kickout-style oil pan helps to direct oil away from the crankshaft and towards the sump, reducing windage and improving engine performance. This feature is especially important in racing conditions, where oil control and uninterrupted oil supply are critical.

The kicked-out sump in a kickout-style oil pan increases the oil capacity of the pan without raising the oil level closer to the windage. This design feature is advantageous in racing applications where engine and chassis builders aim for the lowest possible engine position, which can limit oil pan depth and volume.

Additionally, the fully baffled sump with trap doors ensures that oil is directed to and contained around the oil pump pickup, even during harsh racing conditions involving high g-forces and rapid changes in acceleration, deceleration, and direction.

The combination of the louvered windage tray and kicked-out sump in a kickout-style oil pan enhances oil control, improves engine performance, and ensures a reliable oil supply during intense racing conditions. These features make kickout-style oil pans a versatile choice for a range of motorsports and performance vehicles.

They can be made of steel or aluminium

Kickout-style oil pans can be made from steel or aluminium. For example, Moroso Power Kickout Series Oil Pans are made from steel.

The material used for oil pans is an important consideration, as it must be durable enough to withstand the heat and pressure of the engine. Steel is a strong and durable material that can handle high temperatures, making it a good choice for oil pans. Aluminium is another option that is often used for oil pans. It is a lightweight material that is also good at conducting heat, which can help with cooling the oil.

In addition to the material, the design of the oil pan is also crucial. Kickout-style oil pans have a unique design that helps to increase the oil capacity of the pan without raising the oil level closer to the windage. This is achieved by building wings into the bottom of the pan, allowing for greater oil volume. This design also helps to move the oil level away from the rotating assembly, providing additional ground clearance.

The choice between steel and aluminium for kickout-style oil pans depends on various factors, including cost, weight, and heat conduction properties. Both materials have their own advantages and are commonly used in the construction of oil pans.
