The F20C engine, known for its high-revving capabilities and impressive performance, is a favorite among car enthusiasts. One of the most effective upgrades for this engine is the installation of a performance camshaft. In this article, we will explore how a camshaft swap can yield an additional 15-20 horsepower, particularly when using Competition Cams.
Understanding the F20C Engine
The F20C is a naturally aspirated 2.0L inline-four engine that powers the Honda S2000. It is renowned for its high specific output and exceptional rev range. With a factory output of around 240 horsepower, the F20C is already impressive, but enthusiasts often seek more power through various modifications.
What is a Performance Camshaft?
A performance camshaft is a critical component that affects the engine’s airflow, timing, and overall performance. By altering the lift and duration of the engine’s valves, a camshaft can significantly improve horsepower and torque. When upgrading to a performance camshaft, it’s essential to consider the engine’s tuning and supporting modifications.
Benefits of Swapping to Competition Cams
Competition Cams is a well-known manufacturer of performance camshafts that cater to a variety of applications, including the F20C engine. Swapping to a camshaft from Competition Cams can provide several advantages:
- Increased Horsepower: Expect an additional 15-20 horsepower with the right camshaft.
- Improved Torque Curve: Enhanced mid-range torque for better drivability.
- Better Throttle Response: More immediate power delivery when accelerating.
- Custom Tuning Options: Compatibility with aftermarket ECUs for optimal performance.
Choosing the Right Competition Camshaft
When selecting a camshaft from Competition Cams, it’s essential to consider your performance goals and the specific characteristics of the camshaft. Here are some factors to keep in mind:
- Lift and Duration: Higher lift and longer duration can lead to more power but may require additional modifications.
- Profile Type: Decide between a street-friendly cam or a more aggressive race cam based on your driving style.
- Compatibility: Ensure the camshaft works well with your existing engine components.
- Support Modifications: Consider whether you need upgraded valve springs, retainers, or tuning to maximize the camshaft’s potential.
Installation Process
Installing a new camshaft requires a good understanding of engine mechanics. Here’s a general outline of the installation process:
- Gather Tools and Parts: Ensure you have the necessary tools, including a torque wrench, camshaft alignment tool, and any new gaskets or seals.
- Remove the Valve Cover: Start by taking off the valve cover to access the camshaft.
- Remove the Timing Chain/Belt: Carefully remove the timing chain or belt to free the camshaft.
- Swap the Camshaft: Replace the old camshaft with the new Competition Camshaft, ensuring proper alignment.
- Reassemble: Reinstall the timing chain/belt and valve cover, making sure all components are torqued to specifications.
Tuning After Installation
After installing a new camshaft, tuning is crucial to achieving optimal performance. A proper tune will ensure the engine runs smoothly and efficiently with the new camshaft. Here are some tuning options:
- ECU Remapping: Consider remapping the ECU to accommodate the new camshaft specifications.
- Dyno Tuning: Use a dynamometer to fine-tune the engine’s performance and make adjustments as necessary.
- Monitor A/F Ratios: Ensure that air-fuel ratios are within optimal ranges for best performance.
Conclusion
The F20C performance camshaft swap is an excellent way to enhance the engine’s power output significantly. By choosing a quality camshaft from Competition Cams and following the proper installation and tuning procedures, enthusiasts can achieve an additional 15-20 horsepower, making their driving experience even more exhilarating. Whether on the track or the street, a camshaft upgrade is a worthwhile investment for any F20C owner.
