Windage Trays: Reducing Oil Splash, Improving Engine Performance

A windage tray is an engine control part that regulates the flow of oil within the crankcase. It acts as a physical barrier between the moving crank and the oil supply in the pan, reducing drag and friction. By preventing oil from splashing around the crank, the windage tray allows the crank and rods to move more efficiently, improving horsepower and engine performance. Additionally, it helps control the temperature of the oil by minimising aeration and frothing, which can lead to oil starvation and reduced viscosity. While windage trays are not necessary for daily-driven or stock vehicles, they are commonly found in racing and high-performance applications where acceleration occurs at higher RPMs.

A windage tray prevents oil aeration and subsequent oil feed issues

A windage tray is an essential component in preventing oil aeration and the subsequent oil feed issues that can occur in an engine. Windage, or the flow of air within the crankcase, can cause aeration of the oil, leading to oil feed issues and a decrease in engine performance.

When a piston moves down in the cylinder bore, the air under it is pushed into the crank area. As the piston moves up, it pulls air behind it. Additionally, the rotating assembly churns the air and mixes oil into it. This air movement can have negative effects on the oil, leading to aeration. Aerated oil does not pump smoothly and can cause oil feed issues as oil pumps are designed to move fluid, not froth.

This is where a windage tray comes into play. It acts as a physical barrier, separating the violently moving crank from the oil supply. By doing so, it regulates the flow of oil within the crankcase, allowing the crank and rotating assembly to move more freely and efficiently. This, in turn, improves engine performance and horsepower.

The windage tray also helps prevent oil from splashing onto the rotating assembly, which can cause drag and reduce engine performance. With the windage tray in place, oil movement is more controlled, and it can return to the oil supply efficiently without creating froth or aeration.

Furthermore, the windage tray helps maintain oil temperature by preventing excessive churning and aeration. Aerated oil does not dissipate heat as effectively as clear liquid oil, leading to increased oil temperatures and a decrease in viscosity. This can further impact the oil's ability to function properly within the engine.

In summary, a windage tray is a crucial component in preventing oil aeration and subsequent oil feed issues. By regulating oil flow, separating the crank from the oil supply, and preventing oil splashing, the windage tray improves engine performance, horsepower, and overall efficiency.

It keeps oil temperatures low, maintaining oil viscosity

A windage tray is an important component of an engine's oiling system, helping to regulate the flow of oil within the crankcase and maintain optimal oil temperatures and viscosity.

Windage, or the flow of air within the crankcase, can have negative effects on the oil in the system. As the pistons move up and down, air is pushed into and pulled from the crank area, churning the oil and creating aeration. This aerated oil does not pump smoothly and can cause oil feed issues, leading to oil starvation. Additionally, engine oil mixed with air does not dissipate heat as effectively as clear liquid oil, resulting in increased oil temperatures.

This is where a windage tray comes into play. The tray acts as a physical barrier, separating the violently moving crank from the oil supply in the pan. It allows oil to drain into the sump without affecting the scavenging of oil already there. By keeping the oil away from the rotating assembly, the windage tray helps to prevent aeration and maintain the optimal viscosity of the oil.

The design of the windage tray is crucial to its effectiveness. It can be made from either a mesh screen or steel, with each material offering unique advantages. The mesh design allows oil to pass through the tray, while the solid steel design provides a more effective barrier against oil splashing. Additionally, the windage tray should be positioned as close to the rotating assembly as possible to optimize its ability to control the flow of oil.

The benefits of a windage tray include improved horsepower and performance. By regulating the flow of oil, the windage tray reduces drag and friction on the crank and allows the rotating assembly to move more freely. This results in increased horsepower and improved engine performance. Furthermore, the windage tray helps to maintain oil temperature by preventing excessive oil splashing, which can act as a heat sink and introduce additional heat into the oil supply.

In summary, a windage tray is an essential component in maintaining the health and performance of an engine. By keeping oil temperatures low and preventing aeration, the windage tray helps to maintain the optimal viscosity of the oil, ensuring the engine can operate efficiently and effectively.

The tray reduces crankshaft drag, allowing the engine to gain more power

A windage tray is an engine control part that regulates the flow of oil within the crankcase. It acts as a physical barrier between the moving crank and the oil supply in the pan, reducing crankshaft drag and allowing the engine to gain more power.

The tray optimises the performance of the engine by keeping the windage (flow of air within the crankcase) around the crank separate from the oil in the sump area. This allows oil to enter the sump without interference and prevents oil in the sump from getting into the rotating assembly during vehicle motion.

The windage tray also helps to control the movement of oil, preventing it from sloshing around and causing aeration. Aerated oil does not pump smoothly and can cause oil feed issues, as well as increasing oil temperatures and reducing viscosity. By keeping the oil under control, the windage tray reduces drag and friction on the crankshaft, allowing the engine to run more efficiently and gain more power.

The benefits of a windage tray are particularly noticeable in racing and high-performance applications, where vehicles are accelerating at higher RPMs. However, even in everyday vehicles, oil flow management is important for overall engine performance. While a windage tray is not necessary in all cases, it can help to maximise the performance of the engine and gain horsepower.

It acts as a physical barrier between the crank and oil supply

A windage tray is an engine control part that acts as a physical barrier between the moving crank and the oil supply in the pan. It helps regulate the flow of oil within the crankcase, allowing the crank and rotating assembly to move more freely. This is important for overall engine performance, whether in an everyday vehicle or a race car setup.

The windage tray keeps the windage (flow of air within the crankcase) around the crank separate from the oil in the sump area. It allows oil coming off the crank to enter the sump without affecting the scavenging of oil already there. This controlled flow of oil enables the rotating assembly to move more efficiently during acceleration, resulting in improved horsepower and performance.

The windage tray is made from either a mesh screen or steel to suit different engine needs. Both designs physically separate the sloshing oil from the moving crank to optimise performance. The tray can be easily assembled with windage tray bolts for many high-performance projects.

While windage trays are not necessary for daily-driven or stock applications, they are commonly found in racing and high-performance vehicles due to their higher RPM acceleration. However, regardless of the vehicle type, it is crucial to maintain oil control and reduce the chance of losing oil pressure when driving.

A windage tray is especially important for racing and high-performance applications

A windage tray is a critical component of an engine’s oiling system, designed to enhance engine performance and efficiency. It is especially important for racing and high-performance applications where every bit of performance matters.

In racing and high-performance engines, the engine tends to operate at high RPMs, generating oil aeration and increasing oil temperatures. This can lead to several issues, including increased oil foaming, reduced engine efficiency, and decreased power output.

The windage tray helps to combat these issues by acting as a physical barrier between the rapidly rotating crankshaft and the engine's oil supply. It prevents the oil from being whipped up and thrown around by the crankshaft, reducing the turbulence and allowing the oil to settle. This, in turn, maintains oil pressure, prevents oil starvation, and ensures efficient lubrication of critical engine components.

The benefits of using a windage tray in racing and high-performance applications include:

• Improved engine efficiency: Reduced oil foaming and improved lubrication lead to increased power output and fuel efficiency.
• Enhanced engine longevity: Better lubrication results in less wear and tear on the engine, extending its lifespan and lowering maintenance costs.
• Increased oil control: Windage trays help maintain a consistent oil supply to crucial engine components, ensuring proper lubrication at all times.
• Reduced oil contamination: By preventing excessive oil churning and foaming, windage trays minimize the risk of oil contamination and the formation of harmful sludge.
• Lower oil temperatures: Improved oil control can lead to lower oil temperatures, which is essential for maintaining engine performance and preventing overheating.

In summary, a windage tray is a valuable addition to racing and high-performance engines, optimizing their performance and longevity. It ensures that the engine stays properly lubricated, prevents damage to crucial components, and maximizes power output. While there may be some minor decreases in horsepower and torque output due to restricted oil movement, the benefits of improved engine health and performance far outweigh this small trade-off.
