Cam Duration vs Lift: Which Is Better?

When it comes to cam duration vs lift, which is better? This is a question that has been asked by many engine builders and performance enthusiasts over the years. The answer to this question is not as simple as it may seem. In order to make an informed decision, it is important to understand the basics of camshaft design and how each parameter affects the overall performance of an engine.

Cam duration is the length of time, in crankshaft degrees, that the cam lobe is in contact with the valve. Lift is the distance, in inches, that the valve is raised off of the seat. A longer duration cam will stay in contact with the valve for a longer period of time, and will provide more torque and horsepower throughout the engine’s rpm range. However, a longer duration cam will also require more valve lift to achieve the same results.

A shorter duration cam will provide less torque and horsepower than a longer duration cam, but it will also

What’s more important cam lift or duration?

This is a question that has been debated for many years, and there is no definitive answer. Some people believe that cam lift is more important, while others believe that duration is more important. The truth is that both cam lift and duration are important, and they both play a role in the performance of an engine.

Cam lift is the distance that the cam lobe moves up and down. This is important because it determines how much valve lift is created. The more valve lift that is created, the more air and fuel can be drawn into the engine, and the more power the engine can produce.

Duration is the amount of time that the cam lobe is in contact with the valve. This is important because it determines how long the valve is open, and how much air and fuel can be drawn into the engine.

Both cam lift and duration are important in determining the performance of an engine. However, it is important to choose the right combination of cam lift and duration

What does more duration do for a camshaft?

The duration of a camshaft is its most important specification. Duration is how long the valve is open, measured in degrees of crankshaft rotation. More duration means the valve is open longer, which allows more air and fuel into the engine. This makes the engine more powerful and efficient.

There are two main types of duration: duration at 0.050″ valve lift and duration at max valve lift. Duration at 0.050″ valve lift is the most important, because it is the duration at which the valve is actually opening and closing. Duration at max valve lift is less important, because the valve is only open for a short time at high engine speeds.

There are also two main types of duration: duration at 0.050″ valve lift and duration at max valve lift. Duration at 0.050″ valve lift is the most important, because it is the duration at which the valve is actually opening and closing. Duration at max valve lift is less

What does more lift on a camshaft do?

Lift is the distance the cam lobe moves off of its baseline, or the height the cam lobe moves off of the camshaft. More lift means the cam can open the valves further, resulting in more airflow into and out of the engine. This can result in more power, but it also comes with a trade-off: increased wear on the valves and valvetrain.

Does cam duration affect idle?

The answer to this question is yes, cam duration can affect idle characteristics. A cam with a longer duration will typically have a higher idle speed than a cam with a shorter duration. This is because a cam with a longer duration will open the valves further and keep them open for a longer period of time, which increases the airflow into and out of the engine. This increased airflow can cause the engine to idle at a higher speed.

What makes a cam choppy?

There can be a lot of reasons why a cam might be choppy, but here are the most common ones:

1. The cam is not getting enough power. This can be due to a weak battery, a dirty or clogged air filter, or a malfunctioning fuel pump.

2. The cam is not properly lubricated. This can be due to a lack of oil, old or dirty oil, or a clogged oil filter.

3. The cam is not getting enough air. This can be due to a dirty air filter, a malfunctioning carburetor, or a clogged intake manifold.

4. The cam is not getting enough fuel. This can be due to a malfunctioning fuel pump, a clogged fuel filter, or a dirty carburetor.
