What are the advantages and disadvantages of camshafts?

If you’re wondering if the horsepower of a camshaft is increased then the answer is yes.

For a stock cam that is high-performance, cam boosts horsepower it is necessary make other adjustments, including replacing the intake air, the inlet manifold for the exhaust, injectors and much more, which we’ll cover further down.

What Does a Camshaft Do in a Car?

A good camshaft will increase the power of your car by between 10 and 20 times according to the camshaft you choose.

The camshaft rotates that triggers the engine’s valves for exhaust and intake. When the shaft rotates it, the cams press on the valve for intake that is spring-loaded through the motion of pistons, and then engage those spark plugs.

The camshaft’s size can also play a role in the performance of a car. A bigger camshaft allows more fuel and air into the engine’s cylinder. This makes the vehicle run faster and also adjust the timing of the camshaft to ensure that the camshaft is behind or ahead of the engine’s performance.

What is a Performance Camshaft?

Whatever the model of engine, when the camshaft is involved, and it regulates the way the valves are opened and closed. This then controls the intake of air into the engine and fuel mixture, as well as the circulation of air. This will increase engine performance, fuel efficiency in addition to cam timing and even emissions.

These factors all affect the amount of power your car will be able to produce. If your goal is to increase the horsepower of your vehicle then you’ll need to know the basics of everything from exhaust gas options to timing belt tune-up, alternatives for the exhaust valve including fuel flow, bolt-ons etc.

Performance Camshaft HP Gain

Performance cams boost the horsepower your vehicle produces through increasing the speed of valve openings. This makes it accelerate faster.

You’ll experience an uneasy idle when you have an overhead camshaft with performance with that rumble some people would like to hear in their vehicles.

How many HP is the Stage 1 cam add?

The camshaft only adds 10-20 horsepower. The commonly-quoted gain of 50-100 horsepower can only be achieved through the addition of a number of changes throughout Stage 1 and Stage 2.

How many HP is the Stage 2 cam add?

What is the horsepower that Stage 2 camshaft produce? Stage 2 will upgrade the camshaft and improving the intake as well as remapping both the ECU along with the exhaust to complete Stage 1.

It’s possible to feel 20-25 percent more power coming from the engine after you’ve completed the first and 2.

What is the horsepower of Stage 3 cams add? Stage 3 cam add?

Stage 3 can have as much as 40 percent more power than Stage 1. But Stage 1 and Stage 2 must both be modified prior to you can progress to Stage 3.

What is the horsepower of the Stage 4 cam add? Stage 4 cam add?

This Stage 4 upgrade boasts a lower rpm torque , yet provides maximum power. With the correct engine you can attain 460+ whp If you buy an excellent set of head cylinders.

Upgraded Camshaft Benefits

There are many advantages to the adjustment of camshafts, many which boost the performance of your vehicle. We have listed some of these benefits.

Benefit 1

Increase torque in the lower end

Altering the camshafts in order to make sure the cams are behind or ahead can alter the performance of your engine, and, if done properly and correctly, it can improve the performance of your engine. How? By speeding up the timing, it triggers the valve for fuel intake to open and close earlier, which increases low-end torque in the overall. Additionally slowing down the cam will increase the horsepower of high-end engines. However, this will come at the expense of low-end torque.

Benefit 2

Increase the power and increase efficiency

The lobes of the camshaft that have been upgraded will be different in form, allowing the valves open for longer time periods on a more frequent schedule, but with a delay.

This will ensure the best air and fuel delivery as well as an increase in power and efficiency particularly when you opt for lighter, high-quality models.

Benefit 3

Heightens sound

If you’re a total motorhead, then you’ll be awed by the sound that certain vehicles emit. If you’re looking for an incredibly low and deep growl, enhancing the cams in your car is definitely beneficial, since it’ll ensure loud, booming engine sound.

Benefit 4

A greater range of RPMs

People who want to modify their engine to perform more efficiently while staying within an RPM range, may think about camming their vehicle.

Camshaft Upgrade Pros And Cons

Like any other tweak to a car the camshaft upgrade comes with an array of advantages and disadvantages, a few of which we’ve included below.


There are many advantages; two main reasons why cars tend to go for an upgraded camshaft are because of power and sound.

Both of these components can be enhanced by the addition of a new cam. This feature increases the horsepower of your engine and the overall performance of your engine.

For a reliable camshaft, valve timing, fuel filtering and much more it is important to buy high-quality components and ensure the proper fitting of the camshaft accessories.

They could comprise components for timing chains and valve train parts, stock heads and rocker arms, larger cams, as well as other components that influence how crankshafts function and improve performance.


In some states, purchasing an entirely new camshaft is illegal unless you have a car with a certification number for your vehicle.

In this scenario you can change the camera. Another issue is when it comes to insuring and selling your car it is necessary to record all modifications. This could increase the cost and deter people from buying your vehicle in certain circumstances.

Another drawback? The price can be expensive, but many believe that this is worthwhile over the long run.

Is Buying A Car Is It Worth It?

Camming a car is about improving the timing and the duration of the open valve. In motoring terms, it means increasing the timing and lifting of valves.

For a deeper dive to the topic of timing, it is the length of time that it takes for the camshaft’s lobes of the camshaft to open the valves. The higher the speed as well as the lift is, the greater amount of air and fuel the mixture is able to get to the cylinder for optimal outcomes.

If increasing the power of your vehicle is important, then boosting it is a good idea, as it’s a guaranteed method to increase the horsepower.


Are you able to record any vehicle?

The only exception is an engine driven car, but, you’ll likely overcome this if you own an ordinary car. If you’re unsure then it’s advised to talk to an expert mechanic with experience in this field and who can tell you the amount of horsepower your particular vehicle could attain.

Are cammed cars reliable?

Cammed cars are extremely trustworthy, provided that it was upgraded properly with high-quality parts. If not, you’ll likely be paying an enormous bill for repairs, particularly if the air-fuel mix has been altered by the engine or exhaust valves are damaged during the process of upgrading.
