What Does A Camshaft Do In A Car?

If you’re trying to figure out if an engine’s camshaft increases horsepower then the answer is yes.

In order to ensure that a top-performing stock cam boosts horsepower it is necessary make other adjustments, including changing the intake air, the exhale manifolds, the injectors and many more that we’ll discuss further down.

What is a Camshaft Do in a Car?

A high-quality camshaft can boost the power of your car by 10-20 times according to the camshaft you choose.

The camshaft is a shaft that rotates which activates the engine’s cylinder’s valves for exhaust and intake. As the shaft turns the cams push down on the intake valve that is spring loaded by the movement of the pistons. This then triggers those spark plugs.

The camshaft’s size can make a significant difference in the performance of your car. A bigger camshaft allows more air and fuel to the engine’s cylinder. This makes vehicles run more efficiently and also adjusting the timing of the camshaft so that the camshaft is behind or ahead could affect an engine’s performance.

What Does a Performance Camshaft Do?

No matter what kind of engine it is the one that determines how the valves are opened and closed. This then controls the intake of air and fuel mixture, as well as the circulation of air. This will increase engine performance, fuel efficiency as well as cam timing and emission levels.

Each of these elements affects the power that your vehicle will be able to produce. If the goal is to increase the horsepower of your vehicle then you’ll need to know all you can about exhaust gas options to timing belt tune-up, the options for exhaust valves and fuel flow, bolt-ons and more.

Performance Camshaft HP Gain

Performance cams increase the power your vehicle produces because they increase the frequency of valve openings. This makes it accelerate faster.

You’ll experience an uneasy idle when you have an overhead camshaft with performance which gives that rumble many people want in their vehicles.

How many HP is the Stage 1 cam add?

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

How many HP is the Stage 2 cam add?

How much horsepower does Stage 2 camshaft make? Stage 2 involves upgrading the camshaft and changing the intake and mapping both the ECU along with the exhaust to complete Stage 1.

You’ll feel 20-25 percent more power from the engine after you’ve completed stage 1 and 2.

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

Stage 3 will provide as much as 40 percent more power than Stage 1. However, Stage 1 and Stage 2 must both be modified prior to you can progress to Stage 3.

What horsepower can the Stage 4 cam add? Stage 4 cam add?

Stage 4 Stage 4 upgrade boasts a lower torque at lower rpm, but delivers peak power. If you choose the right model you can get 460+ whp when you purchase an appropriate set of head cylinders.

Upgraded Camshaft Benefits

There are many benefits to the adjustment of camshafts, many that boost the performance of the vehicle. Here are some of these benefits.

Benefit 1

Enhance torque at the low end.

Altering the camshafts in order to make sure that the cams are not behind or ahead can alter the performance of your engine, and, if done properly it will be beneficial. How? The speeding up of the timing causes the fuel intake valve to open and close earlier, increasing low-end torque in the overall. In addition delay in the cam can increase the horsepower of high-end engines. But, this is at the expense of low-end torque.

Benefit 2

increase the power and increase efficiency

The lobes of the upgraded camshaft are likely to have a different form, which allows the valves to 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 if you go for lighter, high-quality models.

Benefit 3

Heightens sound

If you’re a true motorhead, then you’ll be awed by the sound that certain vehicles produce. If you’re looking for an unassuming and deep growl, enhancing the engine’s cams is definitely beneficial, because it will give you that strong, clear engine sound.

Benefit 4

A higher RPM range

People who want to modify their engine to run more efficiently and within a precise RPM range, might consider camming their car.

Camshaft Upgrade Pros And Cons

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


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

Both of these parts are 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 other components It is essential to buy high-quality components and ensure the proper fitting of the camshaft accessories.

This could include components for timing chains and valve train parts, stock heads rocker arms, larger cams, as well as other components that influence how crankshafts operate and enhance performance.


In some states, purchasing an entirely new camshaft is prohibited unless your vehicle is registered with a car certification number.

In this instance 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 raise prices and deter people from buying your vehicle in certain circumstances.

Another issue? The price is expensive, yet many people think it is worth it in the long run.

Is Buying A Car worth it?

Camming a car is about improving the timing and the duration of the closing of the valve. In terms of motoring increasing the timing and lifting that the valves.

For a deeper dive to the topic of timing, it is the length of time it takes for the camshaft’s shaft to open its valves. The more precise the timing and the higher the lifting, the greater amount of air and fuel that the mixture will get to the cylinder for optimal outcomes.

If increasing the performance of your car is important, then boosting it is a good idea, as it’s a sure method to increase the horsepower.


Are you able to record any vehicle?

The only exception is the case of a car powered by a rotary engine; however, it is possible to make it work if you have an ordinary automobile. If you’re not sure then it’s recommended to consult an expert mechanic with experience in this field, and who can tell you the amount of horsepower your specific vehicle can 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 end up paying the cost of repairs, particularly if the air-fuel mixture was tampered by the engine or exhaust valves are damaged as a result of the process of upgrading.
