The B18C5 engine, known for its high-revving capabilities and robust performance, has become a popular choice among automotive enthusiasts. In this article, we will explore performance testing on the B18C5, focusing on the power gains achieved through the installation of Skunk2 camshafts and a high-flow exhaust system.
Understanding the B18C5 Engine
The B18C5 is a variant of Honda’s B-series engine family, specifically designed for performance applications. It features a DOHC design and is known for its ability to produce high horsepower numbers while maintaining reliability.
- Engine displacement: 1.8 liters
- Configuration: Inline-4
- Power output: Approximately 200 hp in stock form
- Applications: Honda Integra Type R
Modifications Overview
To enhance the performance of the B18C5, we focused on two key modifications: the installation of Skunk2 camshafts and a high-flow exhaust system. Each of these upgrades plays a crucial role in improving airflow and overall engine efficiency.
Skunk2 Camshafts
Skunk2 is renowned for its high-performance camshafts, which are designed to increase the engine’s power band and efficiency. The camshafts alter the timing and duration of the intake and exhaust valves, allowing for better airflow.
- Increased lift and duration for improved airflow
- Optimized for high RPM performance
- Compatible with stock valvetrain components
High-Flow Exhaust System
A high-flow exhaust system is essential for maximizing the performance gains from the camshafts. By reducing back pressure, the exhaust system allows for quicker evacuation of exhaust gases, improving engine response and power output.
- Mandrel-bent piping for smooth airflow
- Larger diameter pipes to reduce restriction
- High-performance muffler design for optimal sound
Performance Testing Methodology
To accurately measure the performance gains from these modifications, we conducted a series of dyno tests. The testing involved comparing the stock configuration of the B18C5 against the modified setup with Skunk2 camshafts and a high-flow exhaust.
- Baseline testing: Stock B18C5 configuration
- Modification: Installation of Skunk2 camshafts
- Modification: Installation of high-flow exhaust system
- Final testing: Dyno runs to measure power and torque
Results of Performance Testing
The results from our testing provided valuable insights into the effectiveness of the modifications. Below, we present the power and torque figures obtained throughout the testing process.
- Stock B18C5: 200 hp and 130 lb-ft of torque
- After Skunk2 camshafts: 220 hp and 140 lb-ft of torque
- After high-flow exhaust: 230 hp and 145 lb-ft of torque
Analysis of Power Gains
The power gains observed from the modifications were significant. The Skunk2 camshafts alone contributed to an increase of 20 hp, while the addition of the high-flow exhaust system provided an additional 10 hp. This demonstrates the synergistic effect of combining these two upgrades.
Conclusion
In conclusion, the performance testing of the B18C5 engine with Skunk2 camshafts and a high-flow exhaust system yielded impressive results. The modifications not only enhanced power output but also improved the overall driving experience. For enthusiasts looking to maximize the potential of their B18C5, these upgrades are highly recommended.
