What Does Cammed Mean Car

Cammed in the context of cars refers to a modification made to the engine. It typically involves installing a performance camshaft, which is an essential part of an internal combustion engine.

The camshaft is responsible for controlling the opening and closing of the engine’s valves, which allows for the intake of air and fuel and the expulsion of exhaust gases. A performance camshaft, also known as a “cam,” is designed to optimize engine performance by altering the timing and duration of the valve operation.

When a car is “cammed,” it means that the original stock camshaft has been replaced with a higher-performance aftermarket camshaft. This modification can significantly improve engine power and torque, especially at higher RPMs.

There are different types of camshafts available, each with its specific profile and characteristics. Some cams are designed for low-end torque, while others are focused on top-end horsepower. The choice of camshaft depends on the desired performance goals and the engine’s specific characteristics.

It is important to note that camming a car is not a simple modification and requires careful consideration and adjustments to other engine components. Installing a performance camshaft may require modifications to the valve springs, valve lifters, cylinder heads, and other related parts to ensure proper fitment and operation. Additionally, the engine’s computer system may need to be recalibrated to accommodate the changes made by the new camshaft.

Cammed cars often have a distinct sound due to the altered valve timing and duration. The engine may produce a lopey idle, characterized by a choppy and irregular rhythm, which is often a desirable sound for performance enthusiasts.

The performance gains achieved by camming a car can vary depending on several factors, such as the specific camshaft used, the engine’s condition, and the accompanying modifications. When done correctly, camming can provide significant improvements in horsepower, torque, and overall engine response.

However, it’s essential to consider that camming a car may also have some downsides. Depending on the camshaft selected, the engine’s low-end torque may be compromised, resulting in a loss of drivability at lower RPMs. Additionally, fuel economy may be negatively affected due to the altered valve timing and increased airflow.

In conclusion, camming a car refers to installing a performance camshaft to enhance engine performance. It can provide significant gains in power and torque but requires careful consideration and adjustments to other engine components. Proper installation and tuning are crucial to ensure optimal performance and reliability.
