What is camming a car?

Camming a car refers to the modification of its camshaft, also known as the cam, which controls the opening and closing of the engine's valves. The camshaft is a crucial component of the engine's valvetrain system and plays a significant role in determining the engine's power and performance characteristics.

Camming a car involves replacing the stock camshaft with a higher performance or aftermarket camshaft. This modification aims to optimize the engine's airflow, fuel mixture, and valve timing, thereby increasing power output, torque, and overall performance.

There are different types of camshafts available, such as hydraulic, flat tappet, and roller camshafts, each offering specific benefits. Some common modifications include increasing the duration of valve openings, known as a longer duration cam, or altering the lift of the valve, known as a higher lift cam.

Benefits of camming a car can include:

  1. Increased horsepower and torque: By optimizing the valve timing and opening duration, camming can improve the volumetric efficiency of the engine, resulting in increased power output and torque.

  2. Enhanced throttle response: Upgrading the camshaft can improve the engine's response to throttle inputs, allowing for quicker acceleration and responsiveness.

  3. Improved engine breathing: Camming can enhance the engine's airflow, enabling better combustion efficiency and potential increases in fuel efficiency.

  4. Customization: Camming provides an opportunity for car enthusiasts to tailor their engine's performance to their desired driving style, whether it's focused on daily commuting, racing, or towing capabilities.

However, camming a car is not a simple task and may require additional modifications to the engine system. It is recommended to consult with knowledgeable professionals or engine tuners who can guide you through the process and help determine the ideal camshaft modifications for your specific car and its intended use.

Furthermore, it is important to consider that camming a car may affect its emissions, fuel consumption, and overall driveability. Some states or regions may have regulations regarding the modifications allowed, so it is essential to be aware of local laws and emissions requirements before making any changes.
