Looking to get more power from 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 great thing.
It’s likely that you’ve come to a conclusion that you need to replace your camshaft based on discussion forums and YouTube videos. This is a sensible choice to consider a performance camshaft has been proven to boost power, however the main issue is what power will it bring?
While the camshafts boost horsepower, it’s less than 10-20 horsepower and usually less than a 10% gain. The frequently-quoted 50-100 horsepower increase can only be achieved through an array of related modifications made through the Stage 1 or Stage 2 modifications.
In this article, we’ll go over how the camshaft functions and why changing to a higher-performance option can boost power, as well as ways to increase the power output. Continue reading to learn more!
What is the Camshaft Function?
The camshaft is a rod which is located at the bottom or, more often, at in the upper part on the top of an engine. It comes with precisely-machined cams that precisely timed to close and open the valves.

The camshaft that is located at the lower part in the block of an engine is part of a cam system. The name suggests the camshaft is pushing rods, which are extended towards the valves, and then control the valves.
In the event that the camshaft’s position is in the upper part of the shaft that is what we refer to as an overhead or overhead-camshaft. There’s a term that’s been used to describe the dual overhead camshaft, it’s a type of system that includes two camshafts. One handles the exhaust valve while another controls intake valve.
When you hear the word 16-valve four-cylinder engine it is a reference to the fact that the camshaft is equipped with 4 sets of cams, each one responsible to operate the two intake and exhaust valves. In contrast, a dual-cam engine includes two camshafts, each with eight cams per.
Does The Camshaft Impact the power?
The engine produces power through inflaming the mixture of fuel and air after it is properly mixed and pressurized. The camshaft is opened then closes an intake valve changing it could result in an oxygen-rich mixture and a more powerful ignition.
The camshaft that comes with the stock model is precisely designed to provide longevity, maximum powerand efficiency. The reason why a higher-performance camshaft produces an increase of 10-20 horsepower is because it does not affect the quantity of fuel that is pumped into the piston.
Making more power from your engine can be a constant series of improvement. The new camshaft could be blocked due to the injectors for fuel. Install better fuel injectors and you’ll require better 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 achieve the 50-100 horsepower increase but at that moment, you have to decide whether the entire upgrade is worth the investment.
Should You Change the Camshaft
Removing the camshaft solely for the purpose of increasing performance is an expensive and inefficient method to gain more horsepower, particularly in the case of an older model of vehicle.
In time, the engine gets less power due to wear and accumulation of carbon and dirt deposits. Cleaning the system by hand wherever you can and adding fuel additives can bring more power back in the engine than the new camshaft can do.
However, if you’re required to replace your camshaft eventually selecting a high-performance 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 the engine, you should think about replacing various components, from the intake to exhaust. In accordance with the law in your state, you could begin by eliminating the catalytic converter in the exhaust and installing an entirely new exhaust manifold.
