How Does The Camshaft Work?

Needing to increase the power output of the engine is a scenario that we’ve all experienced. However, regardless of the size or power it provides, the ability to squeeze out an extra bit is always a positive thing.

You’ve probably come to the conclusion that it’s time to replace your camshaft based on discussion forums and YouTube videos. This is a sensible choice to consider a performance camshaft has been shown to increase performance, yet the key issue is what power will it bring?

While the camshafts boost horsepower, it’s less than 10-20 horsepower, and typically less than a tenth of a percent increase. The commonly-quoted increase of 50-100 horsepower can only be achieved through the addition of a number of modifications in the Stage 1 or Stage 2 modifications.

In this post, we’ll talk about the workings of camshafts and the reasons for changing to a higher-performance option boosts power, and also methods to boost the output of horsepower. Read on to learn more!

What is the Camshaft Function?

The camshaft is a rod which could be found in the bottom or, more often, at on top on the top of an engine. It is equipped with precisely-machined cams that are precisely timed to close and open the valves.

Camshaft situated at the lower part on the bottom of the engine block part of a cam system. Like the name suggests the camshaft is pushing rods which extend to the valves to control the valves.

When the camshaft’s location is situated in the upper part of the shaft the roof, it is referred to as the overhead camshaft. There’s a term that’s been used to describe a dual overhead camshaft . it’s a type of system that includes two camshafts. One handles the exhaust valve, and another controls an intake valve.

If you are familiar with the phrase 16-valve four-cylinder engine it is a reference to the fact that the camshaft is equipped with the four set of 4 cams, each one responsible for the operation of two intake and exhaust valves. A dual-cam model has two camshafts that have eight cams in each.

Does The Camshaft Impact the Power?

The engine produces power through sparking an air-fuel mixture after it has been mixed properly and pressurized. Since the camshaft opens to close the intake valve altering it can result in an oxygen-rich mixture and provide a stronger ignition.

The camshaft that comes with the stock model is specifically designed to guarantee longevity, optimal performance, and fuel efficiency. The reason why a higher-performance camshaft can result in an increase of just 10-20 horsepower is because it doesn’t alter the amount of fuel that gets pumped into the engine.

The ability to get more power from your engine can be a continuous improvement cycle. The new camshaft could be blocked through the fuel injection system. Install better fuel injectors and you’ll need more valves. Change them out and you’ll need an improved intake and exhaust manifolds to let out all air. After all of this, you’ll gain 50 to 100 horsepower but at that moment, the question is whether the upgrade is worth the cost.

Should You Change the Camshaft

The camshaft is replaced solely to boost performance is an expensive and inefficient method of gaining more horsepower, particularly in the case of an older model of vehicle.

As time passes, the powertrain is weakened by wear and accumulation of carbon and dirt deposits. Cleaning the system by hand wherever you can and adding fuel additives can give more power for the motor than the new camshaft can do.

If you need to replace your camshaft eventually selecting a high-performance aftermarket replacement over costly standard camshafts isn’t an option to consider.

If you’ve decided at gaining more power from the engine, you should think about changing a variety of components, from intake to exhaust. In accordance with the law in your area, you can begin by removing the catalytic converter in the exhaust and installing an entirely new exhaust manifold.
