How Much Horsepower Do Camshafts Add
To begin, you must realize that the camshaft is one of the most important elements of a car’s engine since it controls the valve openings in the engine.
The camshaft may also be used for a variety of other tasks, but the engine’s layout determines how it functions. To comprehend what a camshaft does and why it is necessary, you must first grasp how it executes its activities and why they are required.
The camshaft is a mechanism that changes the duration and timing of valve opening to convert crankshaft power into rotational motion. Although it isn’t as straightforward as one-two-three, increasing horsepower is possible in modest steps. Making more power isn’t simply about doing one thing. To obtain the advantages you desire, you’ll need to employ many methods.
Changing the cam necessitates double-checking that you’re using the correct cam for the best results. You should consult with someone who is knowledgeable about your objectives. Otherwise, you could waste money and obtain disappointing results as a result of this.
Camshafts are available in a variety of shapes and sizes for a wide range of applications. Explain to someone who knows about camshafts what you want to achieve. If you apply too much cam, the vehicle may not be able to drive on the road. You won’t obtain the result you desire if it’s too little or excessive.
Don’t think of putting a new camera on and calling it a day. To achieve your objectives, you’ll need to take into account what you want to accomplish with the engine. It’s less expensive than starting from scratch if you approach it once with a plan.

What is a camshaft?
A camshaft is a mechanism that converts rotary motion to rotation. The cams and shaft of a camshaft are two separate components of the machine that convert movement into rotation.
A camshaft’s primary function is to open and shut the intake and exhaust valves, allowing fuel, air, and gas to escape from the cylinder.
Camshafts convert rotary motion to oscillatory or reciprocating motion. Camshafts are integrated into a variety of devices, including internal combustion engines and mechanically controlled ignition systems.
Camshafts are attached in a variety of ways beneath the engine of a car, each one working somewhat differently. Depending on how your car’s engine is built, there are two primary arrangements for a camshaft.
A camshaft is a device that opens and shuts valves inside an engine. A camshaft may be positioned in the cylinder head above the valve, or within the engine block itself. All of a camshaft’s valves have lobes attached to them.
The lobes’ main purpose is to apply pressure on the valves, forcing them to open as they rotate. The form of these lobes may have an impact on a vehicle’s engine performance over time.
What is the function of a camshaft? A camshaft’s primary responsibility is to improve an engine’s performance. The cams and shaft make up a camshaft. The job of opening the intake and exhaust valves is handled by the camshaft. As the shaft spins, the egg-shaped cams (also known as lobes) push the valves open in time with the crankshaft gear. When the camshaft rotates, the cams or lobes rise and fall. As it goes on,the valve spring pushes the valve back up to close it.
A lot of energy can be obtained from the sound waves. This generates more power in the engine, allowing it to operate at a higher capacity. It may also improve acceleration timing and transportation speeds. Because of its drivers’ leg-up in a race that might come down to a split-second victory, this is especially vital in racing cars. Is it true that a camshaft makes a vehicle louder? Yes, in fact. Because of the longer exhaust valve duration, the engine’s noise will become more noticeable. Because the combustion chamber is open for a longer period of time during each cycle, more sound may escape and make a louder boom. Many drivers enjoy the sound produced by this, although the noise itself does not provide additional power to the engine since it makes it appear mightier and scarier in a racing scenario.
How Does The Camshaft Work?
The camshaft is a rod that may be positioned at either the bottom or top of the engine. It contains a set of precisely machined cams, which are timed to open and shut the valves simultaneously.
In a pushrod cam engine, the camshaft is located near the bottom of the engine block. The camshaft pushes a pair of rods that extend towards the valves and operate them, as described by the name.
An overhead camshaft is one in which the camshaft is positioned at the top. An engine with two overhead camshafts, also known as a twin overhead camshaft engine, has two camshafts: one for the exhaust valve, and another for the intake valve.
When the phrase “16-valve four-cylinder engine” is used, it implies that there are eight pairs of four camshafts for each exhaust and intake valve. A dual-cam design would use two camshafts with eight cams on each.
How Much Horsepower Does a Camshaft Add?
Let’s figure out how much horsepower a camshaft adds now that you know what it is and how it functions.
The following is the definition of a camshaft: A camshaft is an internal component that converts reciprocating motion to rotating motion in an internal combustion engine. The answer to this question isn’t as easy as it appears. Depending on the type of camshaft and the engine it’s installed in, a camshaft may bring 10-30 horsepower.
A camshaft can significantly impact the performance of your automobile. A performance cam will provide your car with greater power, quicker throttle response, and, in many situations, improved fuel efficiency. To obtain the most horsepower from a camshaft, it must be designed specifically for your engine.
When shopping for a performance camshaft, you should consider duration and lift. These two qualities of a camshaft are what determine how much horsepower and torque your engine will produce.
Langle is a term used to describe the degree of rotation that a valve makes when open, and lift represents how far it is lifted off the base circle (or lobe). These two values are connected since duration influences when the valve opens and rise is what causes it to do so. To better comprehend how the camshaft works, create a graph with lift on one axis and duration on another.
All engines have a “sweet spot” where you get the most power, but this may take a lot of trial and error on your part. If you put a cam with too little lift and duration in an engine designed for performance use, it will use more gas because less air will enter it.
If you don’t know what you need or would like to experiment on how much horsepower a camshaft adds, it’s probably a good idea to seek the help of an expert.

What is the primary purpose of a camshaft?
The camshaft is a timing mechanism. It regulates the closing and opening of the exhaust and intake valves. It also determines the mounting of the top dead center (TDC) exhaust valve overlap.
There are several journals in the shaft. These journals ride on the engine’s bearings. The lobes, which resemble eggs, operate the valvetrain by moving the pushrods and lifters or directly pushing on the valve stems.
The camshaft is attached to the crankshaft by a timing belt, timing chain, or timing gears. A failure in the camshaft drive may cause the valves to come into touch with the piston crowns, resulting in significant internal damage.
What is the difference between a Crankshaft and a Camshaft?
The camshaft is positioned within the engine block. It has oil passage holes so that the lobes may be lubricated. Because there are two lobes per cylinder in a four-stroke cycle, the camshaft turns once for every two crankshaft rotations.
When the piston reaches top dead center (TDC), it pushes down the intake valve and opens a passage for fuel and air to enter the cylinder. Because of this, higher efficiency is not possible. Overhead cams are no longer used in most cars (OHC).
As the air and fuel mixture enters via the open intake valve, a vacuum is produced, and the spring-loaded exhaust valve opens. The piston’s upward movement compression before being injected into the cylinder. Fuel is then injected into this compressed substance, which is subsequently ignited by an electric spark (spark plugs). Combustion occurs as a result of this
As the piston descends, it expels the burned fuel through the open exhaust valve. The camshaft uses a timing belt or gear to keep everything in sync, ensuring that valves are opening and closing at the proper time.
How to check the camshaft position sensor?
A multimeter is required to examine the camshaft sensor. The multimeter may be used to read a variety of electrical inputs and then generate digital output. It can be used to check the resistance values, verify connections between wires, measure current power, test battery voltages, and so on.
We can check the camshaft position sensor using these procedures.
Locating and Removing the Sensor
The camshaft sensor is located near the crankshaft and above the cylinder heads. Because the camshaft sensor is conveniently positioned adjacent to the valve cover, we can easily access it.
Unscrewing the Plugs and Bolts
Simply turn the adjustable wrench and remove the bolts and plugs. The sensor is linked to the ignition system using a few cables. They must also be removed.
Use the Multimeter
The camshaft sensor must be connected to the multimeter and then set to low resistance or diode mode. Then we need a magnet and plenty of movement. We may determine that the sensor is operating if there is a significant variation in the readings.
Should You Swap The Camshaft
The camshaft is expensive and ineffective in getting more horsepower if just replaced for performance’s sake.
Due to wear and the accumulation of dirt and carbon deposits, the powertrain’s efficiency declines over time. Cleaning out the system manually where possible saves a lot of labor.
However, if you must replace the camshaft in any case, opting for a high-performance aftermarket option rather than expensive stock camshafts is not a bad idea.
If you want to make the most of your engine’s power, consider replacing several parts, from intake to exhaust, entirely. You can begin by eliminating the exhaust catalytic converter and replacing the exhaust manifold depending on what is legal in your state.
Because modern cars are limited by emissions rules, as many of them as possible are preferred. It’s something we addressed in detail in this post, so go have a look at it.
How Much Horsepower Do Camshafts Add?
Stage 2 entails changing the camshaft, but it also includes upgrading the intake and exhaust systems as well as remapping the ECU. When both stages are completed, you’ll be able to extract 20-25% more power from the engine, How Much Horsepower Do Camshafts Add.
What does a Stage 3 cam do to my HP?
The third stage will have up to 40% more power than the factory setup, but you’ll need to finish Stage 1 and 2 modifications as well as a mild big bore of the engine.
Is a camshaft beneficial to a vehicle’s horsepower?
Yes, a camshaft adds 10 to 20 horsepower on average. To extract the maximum performance from the high-performance camshaft, you’ll need to replace other components such as the air intake, exhaust manifold, injectors, and valve heads.
Is a Bigger Cam More Powerful?
Yes, it can. The amount of power that the cam may produce is determined by its size. The size of the camshaft lobes (or cams), as well as their shape and location, influence how tightly they compress an engine’s performance and RPM range. Furthermore, it is claimed that a larger cam installed stock by a certain amount will generate more horsepower. All of the other components that must be chosen for a successful engine may be influenced by this cam.
The camshaft is expensive to replace because it cannot be easily done at home, and the power gains are minor. As a result, we recommend waiting to upgrade your camshaft until you need to change the stock one, and while you’re there, why not improve a few other components and get the power boost you desire? A high-performance camshaft alone will not provide more than a 10% power increase on its own.
With this information, you should now be able to tell how much horsepower a camshaft can bring to your car. Why would individuals use them? What are they used for? Check your own engine out to see if the bearings and valves need attention, because it’s now the ideal time!
