Determining the Rotational Speed of the Head
An important process for engine tuning is determining the rotational speed of the head. This is an important factor in determining performance as it allows for an accurate and consistent measurement of the power output from the cylinder heads. Most modern engines now have the ability to measure the rotational speed of the cylinder heads through a variety of methods, allowing for more accurate tuning than ever before.
The most common way to measure the rotational speed of the head is through a dyno roll test. This method uses the engine itself to measure the rotational speed of the head and is the simplest and most effective way to measure it. The engine is placed on a dyno and the head is spun up, either through the use of a fan or by a dedicated dyno wheel. As the head spins, its rotational speed is measured and can be used to determine the power output of the engine.
Additionally, a more high tech way of determining the rotational speed of the head is through an electronic component known as a Hall effect sensor. This device utilizes a magnet mounted on the top of the cylinder head and a sensor further down the engine. As the magnet passes through the sensor, an electrical signal is created, which can be used to determine the rotational speed of the head. Although this method is more expensive, it yields more accurate results compared to the dyno roll test.
Other methods of determining the rotational speed of the head involve measuring the amount of air being drawn into the cylinder as it is spinning. This method is efficient but does not take into account any variations in the amount of air being drawn in at any given time. As a result, this method is better used for testing purposes rather than for tuning purposes.
Finally, the rotational speed of the head can also be determined by using a spark plug wire. This method works by measuring the electrical signal produced from the spark plug when it is fired, which is then multiplied by a given number to determine the head’s rotational speed. This method is simpler than most other methods, but it is not always accurate as it does not take into account any variances in the amount of air being drawn in at any given time.
In conclusion, determining the rotational speed of the head is an important process in engine tuning and can be done through a variety of methods. The dyno roll test, Hall effect sensors, and spark plug wires are all methods that can be used to determine the speed of the head. Ultimately, whichever method is used will depend on the individual’s performance requirements and budget.
