When enhancing an engine’s performance, car enthusiasts often turn to modifications that can increase horsepower. One popular modification that can make a significant difference is upgrading the camshaft. But how much horsepower does a camshaft add? Knowing how much HP a cam deliver, such as the often-quoted 50-100 horsepower gain, makes a significant difference when driving.
The camshaft is a critical component of an engine’s valvetrain system. It controls the timing of the intake and exhaust valves, determining when they open and close during the engine’s combustion cycle. Optimizing the engine’s performance and increasing horsepower is possible by altering the camshaft profile and lift. It’s important to note that the horsepower gain from a camshaft upgrade depends not solely on the camshaft itself. The performance of the entire engine system, including the intake and exhaust systems, cylinder heads, pistons, and air-fuel mixture, all contribute to the overall power increase.
Additionally, the type of vehicle and its existing power output will impact the potential horsepower increase from a camshaft upgrade. A stock camshaft replacement on a high-performance engine may yield more significant gains than a standard engine with limited modifications. In our guide, you can learn more about whether or not a camshaft will make a huge difference in your car. By the end, you’ll better understand if a crankshaft and camshaft upgrade is worth the time and effort. (Learn How Many Spray Cans To Paint A Car)
How Does A Camshaft Work?
You’ve probably heard of camshafts if you’re interested in increasing your engine’s horsepower. A camshaft is responsible for opening and closing the engine’s valves, which allows air and fuel to enter and exhaust gases to exit.
There are two main types of camshafts: overhead camshaft (OHC) and regular camshafts. The camshaft turns at half the speed of the crankshaft, which means that the camshaft is responsible for opening and closing the valves at the right time. The camshaft is designed with a series of lobes that push against the valves, which causes them to open and close.
The number of lobes on a camshaft can vary depending on the engine’s design and the desired performance. A regular camshaft may have one lobe per valve, while a high-performance camshaft may have multiple lobes per valve.
Will A Camshaft Increase Horsepower?
A camshaft is an essential component of an engine that controls the timing of the valve opening and closing. It is a long, cylindrical shaft with several egg-shaped lobes, known as cams, responsible for pushing open and closing the valves in the engine. The camshaft spins in time with the engine’s crankshaft connected to the pistons. As the camshaft rotates, the cam lobes push against the valve lifters, pushing the intake and exhaust valves open.
The intake valve opens to allow a mixture of air and fuel into the engine’s combustion chamber, while the exhaust valve opens to let out the exhaust gases. The camshaft controls the timing of the valve opening and closing, ensuring that the right amount of air and fuel enters the engine and that the exhaust gases are expelled at the right time.

How Much Horsepower Does A Camshaft Add?
When it comes to increasing your car’s horsepower, the camshaft is a popular choice among car enthusiasts to ensure their car is running at its maximum. The camshaft turns to control the opening and closing of the engine’s valves, affecting the amount of air and fuel that enters the engine. This process can significantly impact your car’s additional horsepower output. So, how much horsepower does a camshaft add? On average, a performance camshaft can increase by around 10-20 horsepower.
However, the amount of horsepower gain will depend on several factors, including the type of camshaft you choose, the engine’s current horsepower output, and many other modifications should you want to upgrade your car. An upgraded cam can add horsepower and torque, improving acceleration and overall performance.
Is Performance Camshaft Worth The Camshaft Upgrade Cost?
Upgrading your camshaft will provide an increase in your engine’s horsepower. However, it’s essential to understand the impact of different camshaft upgrades and accompanying modifications through Stages 1 and stage 2.
A performance camshaft can add 10 to 20 horsepower, about a 5% to 10% increase. Some companies may claim you’ll find their performance camshaft worth 50 to 100 more horsepower, but that’s only after completing a series of other modifications with the new cam.
It’s essential to consider the upgrade stage when upgrading the camshaft to add power. Stage 1 camshaft upgrades are the most basic and typically involve replacing the stock camshaft with a new camshaft. This upgrade will increase horsepower and torque but won’t require any additional modifications. Stage 2 camshaft upgrades are more advanced and require additional modifications to the engine. This upgrade can significantly increase horsepower but also be more expensive due to the required modifications.
Stage 3 camshaft upgrades are the most aggressive and typically require a complete stage 1 and 2 upgrade. This upgrade can substantially increase horsepower, but it can also be the most expensive. It’s important to note that upgrading just the camshaft won’t increase the desired peak power. Accompanying modifications through a stage one cam, stage 2, or a stage 3 cam may be necessary to achieve the desired results. (Read Is A Camaro A Good First Car)
Camshaft Effect To Add Horsepower. Replacement and Installation
If you want to increase your engine’s horsepower, replacing your camshaft is one way to achieve it. However, camshaft work is a complex task requiring a mechanic’s expertise. Before you decide to replace your camshaft, you must determine if replacing your piston and cylinder is necessary.
It may be time to replace your camshaft if you need more power, rough idling, or poor fuel economy. A mechanic can assess the situation and determine if a camshaft replacement is necessary. Camshaft replacement requires the removal of the old camshaft and the installation of a new one. It’s essential to choose the right camshaft for your engine. The wrong camshaft can cause damage to your engine and decrease performance.
Will Camshaft Affect Other Things That Influence Horsepower
Regarding the amount of horsepower a camshaft can add to your vehicle, there are several factors to consider besides the camshaft itself. Here are some of the factors that can influence the horsepower gain you can expect from a new camshaft:
- Air Intake: Upgrading your air intake system can increase the amount of air that flows into the engine, which can help improve horsepower gains from a new camshaft.
- Replacing the Camshaft: If you’re replacing the stock camshaft with a performance camshaft, you may see a larger horsepower gain than simply adding a camshaft to a stock cam system.
- Type of Vehicle: Your vehicle can also affect how much horsepower you can gain from a new camshaft. For example, a dual overhead camshaft engine may gain more horsepower than a single overhead camshaft engine.
- New Exhaust System: Upgrading your exhaust system can also help improve horsepower gains from a new camshaft by allowing the engine to breathe more easily.
- Other Modifications: Remember that adding a new camshaft is just one of many modifications you can make to boost the horsepower. For example, adding a stage 1 or stage 2 modification can also make a difference.
It’s important to note that while many performance camshaft companies claim that their camshafts can add 50 to 100 horsepower, this often-quoted horsepower gain is only possible after completing a series of other modifications with the new cam. A camshaft can increase horsepower by anywhere from 10 to 30, depending on the specific engine and camshaft combination. Ultimately, upgrading your camshaft can be a great place to start if you want to boost your vehicle’s horsepower. Remember that the horsepower gain you can expect will depend on several factors beyond just the camshaft itself.
FAQs: How Much Horsepower from Performance Camshaft Is There?
Can a single camshaft increase horsepower?
