The Honda B16 engine is renowned for its performance and tuning potential. With a stock output of around 125 horsepower, many enthusiasts seek ways to enhance its power and responsiveness. One of the most effective upgrades for increasing horsepower is the camshaft. In this article, we will explore the best camshaft upgrades for B16 engines and how they can help you achieve a power output of up to 160 horsepower.
Understanding Camshaft Functionality
The camshaft plays a critical role in the engine’s performance by controlling the timing and duration of the valve openings. Upgrading the camshaft can significantly improve airflow into and out of the engine, leading to increased power. The right camshaft can optimize engine performance by enhancing the engine’s ability to breathe, especially at higher RPMs.
Factors to Consider When Choosing a Camshaft
- Lift and Duration: Higher lift and longer duration can improve power but may affect drivability.
- Overlap: The amount of time both intake and exhaust valves are open can enhance performance but may lead to rough idle.
- Engine Setup: Ensure the camshaft matches your engine’s configuration and other modifications.
- Intended Use: Consider whether the car is for daily driving, racing, or a mix of both.
