Summary

How Much Horsepower Does a Camshaft Add?

Wanting more power out of the engine is a situation we’ve all been in. No matter the displacement or power it already delivers, squeezing out a bit more is always a good thing.

You’ve likely come to a conclusion that you should replace the camshaft through forum discussions and youtube videos. It’s a sound strategy, as installing a performance camshaft is proven to increase horsepower, but the real question is, just how much power does it add?

While it’s true that camshaft adds horsepower, it’s only 10-20 horsepower and generally less than a 10% increase. The often-quoted 50-100 horsepower gain is only possible with a series of accompanying modifications through Stage 1 and Stage 2 mods.

In this article, we’ll discuss how camshaft works and why swapping to a high-performance option increases power, but also ways to further boost the horsepower output. Keep reading if you want to find out more!

How Does The Camshaft Work?

The camshaft is a rod that can be located at the bottom, or more commonly the top of the engine. It has a set of precisely machined cams that are timed perfectly to open and close the valves.

Camshaft located towards the bottom of the engine block is a part of a pushrod cam system. As the name implies, the camshaft pushes a set of rods that extend towards the valves and operate them.

If the camshaft is located at the top, we call it an overhead camshaft. You’ve heard of a dual overhead camshaft – it’s a system with two camshafts, one handling the exhaust valve, while the other controls the intake valve.

When you hear the term 16-valve four-cylinder engine, it means that the camshaft has four sets of four cams, each responsible for operating the two exhaust and two intake valves. Alternatively, a dual-cam design will have two camshafts with eight cams on each.

Does The Camshaft Affect Power?

The engine generates power by igniting an air-fuel mixture once it has been properly mixed and pressurized. Because the camshaft opens and closes the intake valve, modifying it can create a mixture richer in oxygen and more powerful ignition.

The stock camshaft has been precisely engineered to ensure longevity, optimal power, and fuel economy. The reason why a results in an increase of only 10 to 20 horsepower is that it doesn’t affect the amount of fuel sprayed into the cylinder.

Getting more power out of the engine is a never-ending cycle of improvements. The new camshaft will get bottlenecked by the fuel injectors. Add better fuel injectors, and you’ll need better valves. Swap those out, and you need a better intake and exhaust manifold to deliver and expel all the air. Once you’ve done all of that, you can get the 50-100 horsepower boost, but at that point, the question becomes if the whole upgrade is even worth the money.

How To Replace The Camshaft

If you’ve been reading the guides I’ve written, you’ve likely learned a lot about DIY maintenance and repairs. However, you’ve also picked up that I don’t teach what I don’t know, or at the very least know how to convey properly.

Replacing the camshaft is certainly one of those jobs, doubly so when a custom camshaft is involved. If you want to upgrade the camshaft, find a trustworthy mechanic and ask them if the camshaft you’ve found would work well. This guide will show you just how much work and skill it takes to replace the camshaft.

How Much Does It Cost To Replace The Camshaft?

The cost of an aftermarket camshaft depends on the brand and type of vehicle – $200 to $600 dollars is the general range, but it can easily go into thousands with the best options. You can also get kits that include all the parts you can exchange along with the camshaft. In terms of labor costs, mechanics can charge $1000-2000 because the task is very time-consuming and complicated.

Should You Swap The Camshaft

Replacing the camshaft purely for an increase in performance is a very expensive and inefficient way of getting more horsepower, especially if you’re driving an older vehicle.

Over time, the powertrain loses power through wear and the accumulation of dirt and carbon deposits. Cleaning out the system manually where you can, and adding fuel additives will restore more power to the engine than what a new camshaft adds.

That being said, if you have to replace the camshaft anyway, choosing a high-performance aftermarket option over expensive stock camshafts is not a bad idea.

If you’ve set your sights on getting more power from the engine, then consider going all in and replacing several components, from intake to the exhaust. Depending on what’s legal in your state, you can start by deleting the exhaust catalytic converter and installing a new exhaust manifold.

Modern cars are hindered by emission regulations, so deleting as much as you legally can will let the engine breathe better and output more power. It’s a topic we’ve covered in-depth in this article, so make sure to check it out.

FAQs

How much HP does a Stage 2 camshaft add?

Stage 2 involves upgrading the camshaft, but it also requires you to upgrade the intake and exhaust system as well as remap the ECU to complete Stage 1. When both stages are completed, you can get 20-25% more power out of the engine.

How much HP does a Stage 3 cam add?

Stage 3 will have up to 40% more power compared to the stock setup, but to get there, you’ll have to complete the Stage 1 & 2 modifications, and mild big bore of the engine.

Does a camshaft increase horsepower?

Yes, a camshaft adds 10 to 20 horsepower depending on the setup. To get the full potential of the high-performance camshaft, you’ll have to swap out additional components like the air intake, exhaust manifold, injectors, and valve heads.

Summary

Replacing the camshaft is very expensive as it can’t be easily done at home, and the power gains are minimal. For that reason, I recommend not upgrading your camshaft until you need to replace the stock one, and while you’re there, you can upgrade a few other parts and get the power boost you’re looking for. On its own, a high-performance camshaft will not give you a power increase greater than 10%.

To ensure a high-performance stock cam increases horsepower, you’ll have to make other adjustments such as swapping out the air intake, the exhaust manifold, injectors, and more we will discuss below.

What Does A Camshaft Do In A Car?

A quality camshaft can increase your car’s horsepower by 10 to 20 times, depending on the camshaft you opt for.

The camshaft is a rotating shaft that activates the engine’s cylinder’s intake and exhaust valves. When the shaft turns, cams press down on the spring-loaded intake valve with the motion of the pistons and engages the spark plugs.

The size of the camshaft will also make a difference in a car’s performance. A larger camshaft will allow more air and fuel into the engine’s cylinder, making a vehicle drive faster, as well as adjusting the camshaft’s timing so that cams are behind or ahead can alter an engine’s performance.

What Does A Performance Camshaft Do?

Regardless of the type of engine, the camshaft is in, it controls how the valves open and close. Which then contains the engine’s intake of air and fuel mixture and flow of air. This can then heighten engine performance, fuel economy, cam timing, and emissions.

All of these factors affect how much power your vehicle can achieve. If your ultimate aim is to increase horsepower, you’ll want to learn more about everything from exhaust gases to timing belt tuning, exhaust valve options, fuel flow, bolt-ons, etc.

Performance Camshaft HP Gain

Performance cams increase the horsepower your car produces by increasing the timing of the valve openings, which makes it accelerate more quickly.

You’ll have a rough idle with a performance overhead camshaft that gives that rumble that some people desire on their vehicles.

How much HP does a Stage 1 cam add?

How much HP does a Stage 2 cam add?

How much HP does a Stage 2 camshaft add? Stage 2 is upgrading the camshaft while also upgrading the intake and remapping the ECU and exhaust system in order to complete Stage 1.

You can see 20-25% more power from the engine when you’ve completed stages 1 and 2.

How much horsepower does a Stage 3 cam add?

Stage 3 will have up to 40% more power than the original. However, Stage 1 & 2 modifications must be completed before you can advance to Stage 3.

How much horsepower does a Stage 4 cam add?

The Stage 4 upgrade boasts a lower rpm torque yet still offers peak power. With the correct model, you can achieve 460+whp, providing you invest in a good set of cylinder heads.

Upgraded Camshaft Benefits

There are numerous benefits surrounding adjusting camshafts, many of which heighten the vehicle’s performance. Here we have listed a few of these advantages.

Benefit 1

Improve low-end torque

Switching up the camshafts to ensure the cams are a little behind or ahead will change the engine’s performance, and if done correctly, for the better. How? Speeding up the timing triggers the fuel intake valve to close and open earlier, which heightens low-end torque on the whole. On top of this, delaying the cam will heighten high-end horsepower. However, this will be at the low-end torque’s expense.

Benefit 2

heighten power and efficiency

The lobes on an upgraded camshaft will likely be of a different shape, allowing the valves open for more extended periods on a more regular basis at a delayed time.

This ensures high fuel and air delivery and an increase in efficiency and power, especially if you opt for lighter, quality models.

Benefit 3

Heightens sound

If you’re a complete motorhead, you will likely enjoy the sound certain vehicles make. If your looking for a low, deep growl, upgrading the cams on your vehicle will certainly benefit you, as it will ensure that powerful, throaty engine noise.

Benefit 4

A better RPM range

Those looking to customize their engine and make it perform at a better rate, all within an exact RPM range, will often look into camming their vehicle.

Camshaft Upgrade Pros And Cons

As with every car tweak, camshaft upgrades come with a list of pros and cons, some of which we have listed below.

Pros

There are numerous pros; the two key reasons vehicles tend to opt for an upgraded camshaft is due to power and sound.

Both of these components are heightened with the addition of an upgraded cam, as this feature improves your engine’s horsepower and your overall engine’s performance.

To ensure a camshaft increases valve timing, fuel filters, and more, it’s important to invest in quality parts and ensures the quality fit of your camshaft add-ons.

These may include timing chain parts, valve train components, stock heads, rocker arms, bigger cams, and other popular parts that affect how the crankshafts work and boost performance.

Cons

In certain states, investing in a new camshaft can be illegal unless your car comes with a vehicle certification number.

In this case, it is fine to upgrade the cam. Another con, when it comes to insuring or selling your vehicle, you will need to list all modifications. This can increase prices and put people off buying your car in certain cases.

Another con? The cost can be quite pricy, although most believe this is worthwhile in the long term.

Is Camming A Car Worth It?

Camming a car means improving the timing and duration of the opening of the valve. Or, in motoring terms, heightening the timing and lift of the valves.

To delve further, timing surrounds the length of time it takes the camshaft’s lobes to open the valves. The better the timing and lift, the more fuel and air the mixture will receive into the cylinder for best results.

If boosting your car’s power is key, then camming it is worthwhile, as it is a surefire way to gain more horsepower.

Camshaft Upgrade Cost

In terms of costs, on average, each camshaft replacement will set you back around $1,348 to $1,574. You must also factor in labor expenses, which are about $864 to $1,090.

Then there are the parts, which start at $483, and this is before fees and taxes.

Of course, the exact costs are determined by your exact vehicle and your location. Other costs to consider include future repairs and stage upgrades, resulting in higher costs yet more horsepower.

FAQs

Can you cam any car?

The only exception may be a rotary-powered car; however, you can likely cam it if you own a standard vehicle. If you are unsure, it is always best to speak to a specialist mechanic knowledgeable in this area and who knows how much horsepower your exact vehicle can achieve.

Are cammed cars reliable?

A cammed car is very reliable, providing it has been upgraded correctly using quality parts. If not, you will likely have to foot a hefty bill in repairs, especially if the air-fuel mixture has been tampered with or the exhaust valves have become damaged in the upgrade.

Are cammed cars illegal?

The answer is yes to this in certain states and certain cases, even if altering the mufflers alone is still classed as an upgrade. However, vehicles that showcase a CARB certification number are exceptions to modifications.

What Does Camming A Truck Do?

The term “camming” refers to the modification of a truck’s camshaft. While it may sound justifiably complex, the process of changing out the camshaft allows you to build a custom engine that performs better within a particular RPM range.

But why would you want to do this? And even with good reason, is it really worth your while? Let’s take a closer look at camming and what it does for your truck.

How Does A Camshaft Work? A camshaft is a metal rod that drives an engine. There are one or more cams, or irregular lobes, that actuate parts of the machine along the rod. As the shaft rotates, the larger parts of the lobes can drive levers or pistons. The earliest camshafts date back to the 13th century when Arabs used them to operate water mills. They quickly spread throughout the civilized world, but their use was limited until the industrial revolution. Since that time, camshafts have become an essential part of engine design. In an engine with multiple pistons, such as a truck motor, the pistons don’t fire simultaneously. Instead, they fire in a sequence, one after the other, and the motor’s camshaft raises and lowers the pistons to determine the firing sequence. The camshaft activates a cylinder’s intake and exhaust valves. One lobe will activate the intake valve, followed by a second lobe that activates the exhaust valve. As the shaft rotates, the valves will open and close in the appropriate timing. Moreover, a camshaft determines the duration and nature of the ignition process. For instance, the intake valve may open for a longer or shorter period of time during the upstroke. A small change in this duration can make a big difference in how the engine performs. Different camshafts will allow the vehicle to perform better under certain conditions. For example, allowing more fuel into the cylinder is wasteful at low RPMs, but provides more power at higher RPMs. However, most stock camshafts are generalists and perform best during everyday driving. But if you have a heavy load or you’re racing, you may want a shaft that’s engineered for your specific purpose.

Why Install A Custom Camshaft? Custom camshafts are designed with larger, wider lobes than factory shafts. As a result, the intake valves are open for an extended period. This provides additional power and efficiency at higher engine speeds. While this may sound like an easy decision based on the benefits, camming a truck is not without its downsides. While increased fuel intake is helpful at higher speeds, it’s actually detrimental to your performance at lower speeds. Specifically, your low-end torque will suffer, which can prove problematic for a work truck or for towing since you need a lot of torque to get started with a heavy load. That being said, many truck owners simply prefer a custom camshaft for aesthetic reasons. Yes, it’s inefficient at slow speeds, but it also provides a distinctive, aggressive rumble that makes the engine sound deeper and richer. The downside here is obvious – your gas mileage and towing performance will clearly suffer. However, if you want a deep, roaring engine, camming may be a worthwhile option.

FAQs About Truck Camming So, what can you expect if you cam your truck? Here’s a quick overview of truck camming basics. Does Camming A Truck Make It Faster? In most cases, yes, but it depends on the model of the truck and which custom cam you use. With that said, aftermarket cams are designed for high-end performance, so you can typically expect to experience faster speeds after camming a truck. Are Bigger Cams More Powerful? Yes. A bigger cam will open the intake valve wider, allowing more fuel and air into the cylinder. The larger the cam, the more fuel that is let in. Does Cam Timing Make A Difference? Yes. Adjusting the camshafts so the cams are slightly ahead or behind will alter the engine’s performance. Advancing the timing will cause the fuel intakes to open and close earlier, which improves low-end torque. Conversely, retarding the cam will improve high-end horsepower at the expense of low-end torque. What Is A Lope? A lope is a distinctive, rhythmic rumble that occurs when an engine is idling. It’s highly undesirable for performance, but the sound is much sought-after by gearheads who want their performance truck to sound like a performance truck. A lope is caused by extremely large and wide cams. When cams are wide enough, they will overlap, so in other words, the intake on cylinder two will open before the intake on cylinder one is closed. In addition to the unique sound, a lope is actually desirable when racing. At very high RPMs, the longer valve times will allow for plenty of fuel to enter the cylinders, even as the cam quickly rotates. As a result, the truck won’t lose power when approaching redline. Why Are Cammed Trucks Louder? The main reason that cammed trucks are louder is that there’s more fuel going into the engine, meaning a louder idle and more volume at any given speed. While this is mostly true, the extra noise doesn’t just come from increased fuel intake. It also results from the larger size of the cams themselves. Steeper angles and wider valve openings create more mechanical noise. Why Do Camshafts Break? Camshafts usually break because of a failure elsewhere in the engine. Connecting rods and other parts can break loose and strike the shaft. They can also fail due to defects in manufacturing, such as microfractures. In the rare instance that this occurs, failure usually happens relatively quickly. How Much Does It Cost To Cam A Truck? Assuming you provide your own new camshaft, most shops will charge between $600 and $1,000 to cam your truck. If you plan on doing the job yourself, make sure you set aside an entire weekend. Though it’s not terribly difficult, it can be very time-consuming.
