The Acura RSX Type S is a beloved vehicle among car enthusiasts, particularly those interested in performance upgrades. One of the most significant modifications that can enhance the engine’s power output is the installation of an aftermarket camshaft. In this article, we will compare various aftermarket camshafts available for the RSX Type S and evaluate which ones offer the best power increase.
Understanding Camshaft Functionality
Before diving into specific aftermarket options, it’s essential to understand what a camshaft does. The camshaft controls the timing and duration of the engine’s intake and exhaust valves. By altering these parameters, a camshaft can improve engine performance, efficiency, and responsiveness.
Factors to Consider When Choosing an Aftermarket Camshaft
When selecting an aftermarket camshaft for the RSX Type S, several factors should be considered:
- Lift: The height that the valve is opened, which affects airflow.
- Duration: The time the valve stays open, impacting engine timing.
- Overlap: The period when both the intake and exhaust valves are open, influencing performance at different RPMs.
- Compatibility: Ensuring the camshaft works well with existing engine components.
