The Mazda ND Miata is a beloved sports car known for its lightweight design and agile handling. One of the most effective ways to enhance the performance of this vehicle is by upgrading the camshaft. In this article, we will compare various aftermarket camshafts available for the ND Miata to determine which one adds the most power.
Understanding Camshafts
A camshaft is a crucial component in an engine that controls the timing and duration of valve openings. Upgrading to an aftermarket camshaft can lead to significant performance improvements by optimizing airflow and increasing power output. When considering a camshaft upgrade, it’s essential to understand the specifications and intended use of each option.
Factors to Consider When Choosing a Camshaft
- Lift: The height that the valve opens, affecting airflow.
- Duration: The time the valve remains open, influencing engine performance.
- Overlap: The period when both intake and exhaust valves are open, impacting throttle response.
- Profile: The shape of the cam lobe, which affects how the engine breathes.
- Intended Use: Consider if the camshaft is for street, track, or racing applications.
