Needing to increase the power output of the engine is a scenario that we’ve all experienced. However, regardless of the displacement or the power it currently provides, the ability to squeeze out an extra bit is always a great thing.
It’s likely that you’ve come to a conclusion that you need to replace your camshaft based on forums and YouTube videos. This is a sensible choice to consider a performance camshaft has been shown to increase performance, yet the key problem is, what power will it bring?
Although it’s true that a camshafts increase horsepower, it’s less than 10-20 horsepower, and typically less than a tenth of a percent increase. The frequently-quoted 50-100 horsepower increase can only be achieved through the addition of a number of modifications made through stage 1 or Stage 2 modifications.
In this post, we’ll talk about the workings of camshafts and the reasons for switching to a high-performance model boosts power, and also methods to boost the output of horsepower. Read on to learn more!
What is the Camshaft Function?
The camshaft, also known as a rod, could be found at the bottom or in more cases, in the upper part in the motor. It is equipped with precisely-machined cams that are precisely timed to shut and open the valves.
Camshaft situated at the lower part on the bottom of the engine block component of a pushrod cam system. The name suggests the camshaft is pushing rods which extend to the valves, and then control the valves.
In the event that the camshaft’s position is situated on the top of the hill the roof, it is referred to as an overhead or overhead-camshaft. There’s a term that’s been used to describe a dual overhead camshaft . it’s a system that has two camshafts. One handles the exhaust valve while the other is responsible for intake valve.
When you hear the word four-cylinder engine with 16 valves, it is a reference to the fact that the camshaft contains 4 sets of cams, each one responsible to operate the two intake and exhaust valves. A dual-cam model has two camshafts that have eight cams per.
Does the Camshaft Influence the power?
The engine produces power by inflaming the mixture of fuel and air after it is properly mixed and pressurized. Since the camshaft opens then closes an 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 precisely designed to guarantee longevity, optimal performance, and fuel efficiency. The reason why a higher-performance camshaft can result in an increase of 10-20 horsepower is because it doesn’t alter the amount of fuel that is pumped into the engine.
The ability to get more power from engines is an continuous series of improvement. The new camshaft could be blocked through the fuel injection system. Install better fuel injectors and you’ll need more valves. Replace them and you’ll need an improved intake and exhaust manifolds to eliminate all air. After you’ve completed all this, you’ll be able to gain 50 to 100 horsepower but at that moment, you have to decide whether the upgrade is worth the cost.
Should You Change the Camshaft
Removing the camshaft solely to boost performance can be a costly and inefficient method of gaining greater horsepower, especially when you’re driving an older model of vehicle.
In time, the engine is weakened by wear and accumulation of carbon and dirt deposits. Cleaning the system by hand whenever you can, as well as adding fuel additives, will give more power in the engine than the new camshaft can do.

However, if you’re required to replace the camshaft in the future opting for a high-end aftermarket alternative over the expensive camshafts that are stock isn’t an option to consider.
If you’ve decided to increase the power output of your engine, you should you should think about replacing various components, from the intake to exhaust. In accordance with the law in your area, you can begin by removing the catalytic converter for exhaust and installing an entirely new exhaust manifold.
