High camshaft

Types of High Camshaft

A high-performance camshaft can be found in numerous types, such as the following.

• Flat Tappet Cam:

This is the most fundamental and conventional camshaft type. The followers of this camshaft have a flat bottom that pushes directly against the cam lobes. They are cheaper and lighter and have a smaller engine profile.

• Roller Camshaft:

Roller camshafts use followers that have small rollers on the end. The rollers decrease friction and allow smoother operation. They typically allow for more aggressive cam profiles and higher engine speeds compared to flat-tappet camshafts.

• Hydraulic Camshaft:

These high-performance cam hydraulic flat tappet camshafts are the most common type. They use hydraulic lifters that use engine oil pressure to automatically take up any slack. This eliminates the need for manual adjustments and allows for quieter operation. They are easier to use and provide a smooth and consistent power delivery throughout the RPM range.

• Big-Lift Cam:

These are high lift camshaft that allow the engine's valves to open further. This lets more air and fuel into the cylinders, which can create more power. The downside is that the engine won't be able to make as much power at lower speeds. Big-lift cams give high horsepower at high engine speeds.

• Muscle Car Cam:

These hi lift cam and long-duration camshafts are built for muscle cars. They are a mix of high-performance, big-lift cams, and low-end torque cams. This is because muscle cars need a lot of power over the entire speed range to be "muscle cars." These muscle car cams are a trade-off because they don't provide the best high-lift or low-speed torque performance. However, they offer pretty good performance in both categories. This can be great for muscle cars. That is why they are called muscle car camshafts.

• Supercharger Cam:

A supercharger camshaft is specifically designed to be used with a supercharger. The camshaft is chosen or designed to optimize the engine's performance with the increased airflow provided by the supercharger.

• Turbo Camshaft:

A Turbo camshaft is a performance upgrade that's designed to work well with a turbocharger. The camshaft is chosen or designed to optimize the engine's performance with the increased airflow and higher pressure provided by the turbo.

Specification and Maintenance of High Camshaft

The high camshaft is a critical part of any high-performance engine. There are different specifications to take note of when buying or dealing with such camshafts. Here are some of them.

• Material:

High-performance camshafts are made from high-quality materials that can withstand high stress and temperature, such as hardened steel or alloy materials.

• Duration:

It is the amount of time the valve is open. Longer durations give more power, but only at higher engine speeds. Shorter durations make the engine more responsive at lower engine speeds.

• Lift:

It is how far the valve is opened. More lift allows more air and fuel to enter the chamber, which creates more power.

• Lobe Separation Angle (LSA):

It is the angle between the intake and exhaust lobes. A lower LSA results in more power but less idle quality and low-end torque. A higher LSA provides a smoother idle and better low-end torque.

• Power Band:

The power band is the engine speed range in which the engine produces the most power. Camshaft specifications affect the location and width of the power band.

• Compatibility:

Camshaft specifications must be compatible with other engine components, such as the intake and exhaust systems, cylinder head design, and compression ratio. Incompatibility can lead to poor performance or engine damage.

• Driving Needs:

When selecting a high-performance camshaft, consider the specific driving needs. A camshaft that provides high power at high engine speeds may be suitable for racing applications. In contrast, a camshaft that improves low-end torque and throttle response may be preferable for daily driving.

Proper maintenance is crucial to ensure the performance and longevity of the high-performance camshaft and the entire engine system. Here are some maintenance tips.

• Regular Inspections:

Inspect the camshaft and related components regularly for signs of wear, damage, or corrosion. Check for unusual noises, vibrations, or performance issues that could indicate camshaft problems.

• Oil Change and Quality:

Use high-quality engine oil with the correct viscosity and change it regularly. The engine oil lubricates the camshaft and reduces friction and heat generation. Low-quality or dirty engine oil can lead to premature wear and damage to the camshaft.

• Proper Engine Warm-Up:

Allow the engine to warm up adequately before driving. A cold start puts a lot of strain on the camshaft and other components of the engine. It can cause premature wear and damage.

• Avoid Overloading:

Avoid overloading the vehicle or using it beyond the manufacturer's recommended capacity. Overloading can exert excessive stress on the engine, including the camshaft, and cause damage or premature wear.

• Avoid High Revving:

Avoid revving the engine excessively. High revving exerts a lot of pressure on the camshaft and other engine components, leading to premature wear or damage.

• Professional Inspection:

Consider having a professional mechanic inspect the engine periodically. They have the skills and experience to identify potential camshaft problems early and address them before they worsen.

How to Choose a High Camshaft

When choosing a high camshaft for retail, it's important to consider the target customer's needs and preferences. Here are some tips to consider when choosing a high camshaft:

• Consider the vehicle type:

When choosing a performance camshaft to sell, consider the type of vehicles the customers have. Customers with muscle cars and racing trucks are likely to go for high-performance camshafts. While those with family cars may not want to change the camshaft of their vehicles. In many cases, car owners with high-performance vehicles are more likely to buy and install high-performance camshafts.

• Check the compatibility of the vehicles:

Customers will be looking for high-performance camshafts that are compatible with their vehicles. When stocking, make sure to get the camshafts of popular vehicle brands and makes. Also, ensure that the camshafts are compatible with a range of vehicles. This will help to avoid cases where customers return the products because they don't fit their vehicles. It is also advisable to recommend that buyers consult with experienced mechanics.

• Consider the budget:

High-performance camshafts are available in different price ranges. Stock a variety of options so that customers can find something within their budget. In most cases, basic high-performance camshafts are more affordable than the more aggressive ones. Customers who are willing to spend more will go for the high-lift and long duration camshafts.

• Educate the customers:

Many customers may not understand the benefits of a high-performance camshaft. When marketing the products, educate the customers about the benefits. Explain to them that a high-performance camshaft can improve the horsepower and torque of their vehicles. It can also enhance the sound of the exhaust and improve the fuel efficiency of the vehicle.
