When it comes to automotive racing, every small component counts. The pushrods in your engine are no exception. In fact, upgrading your pushrods can have a significant impact on your engine’s performance. In this article, we’ll explore how pushrods work, why upgrading them can be beneficial, and what to look for when choosing new ones.
What Are Pushrods?
Pushrods are a vital component in your engine’s valvetrain. They transmit the motion from the camshaft to the rocker arms, which then open and close the valves. Pushrods come in different lengths and diameters, depending on the engine’s design and intended use.
Why Upgrade Your Pushrods?
Upgrading your pushrods can lead to increased performance and reliability. By choosing pushrods with a higher quality material, you can increase their strength and durability. This can lead to a more efficient valvetrain, resulting in increased horsepower and torque.
Types of Pushrods
When it comes to types of pushrods, there are two main categories: solid and hydraulic. Solid pushrods are typically used in racing applications, where precise valve control is necessary. Hydraulic pushrods, on the other hand, are more commonly used in street engines.
Pushrods can be made from a variety of materials, including steel, aluminum, and titanium. Steel pushrods are the most common and offer a good balance of strength and affordability. Aluminum pushrods are lighter and more durable than steel, but they come at a higher cost. Titanium pushrods are the strongest and lightest of the three, but they are also the most expensive.
Choosing the Right Pushrods
When choosing new pushrods, it’s important to consider your engine’s specific needs. Factors such as camshaft lift, valve spring pressure, and rocker arm ratio can all affect the pushrod’s length and diameter requirements. It’s also important to choose pushrods that are compatible with your engine’s valvetrain components.
Proper installation of pushrods is crucial for optimal performance and reliability. It’s important to ensure that the pushrods are properly seated and torqued to the manufacturer’s specifications. It’s also recommended to use a high-quality assembly lubricant during installation to prevent damage to the pushrods and other valvetrain components.
Upgrading your pushrods can be a cost-effective way to increase your engine’s performance and reliability. By choosing the right pushrods for your engine’s specific needs and ensuring proper installation, you can maximize your engine’s potential on the racetrack or the street. So, if you’re looking for a small but impactful upgrade, consider investing in new pushrods for your engine.
