The Subaru WRX has long been a favorite among car enthusiasts, particularly those interested in tuning and performance enhancements. One of the most effective ways to increase power in WRX built engines is through the use of aftermarket camshafts and intake systems. This article will compare these two critical components, exploring their benefits, drawbacks, and how they can work together to maximize engine performance.
Understanding Camshafts
Camshafts play a crucial role in controlling the timing and duration of the engine’s valve openings. By altering these parameters, aftermarket camshafts can significantly improve engine performance. Here are some key aspects to consider:
- Types of Camshafts: There are various types of aftermarket camshafts, including performance, racing, and street-friendly options.
- Lift and Duration: Increased lift and longer duration can enhance airflow, leading to better power output.
- Tuning Requirements: Upgrading camshafts often requires additional tuning to optimize engine performance.
Benefits of Aftermarket Camshafts
Aftermarket camshafts can provide several benefits that contribute to increased power and overall engine efficiency. Some of these benefits include:
- Improved Power Band: Aftermarket camshafts can widen the power band, allowing for better performance across a range of RPMs.
- Enhanced Throttle Response: Upgraded camshafts can lead to quicker throttle response, making the car feel more agile.
- Better Engine Sound: Many enthusiasts appreciate the aggressive sound that aftermarket camshafts can produce.
Drawbacks of Aftermarket Camshafts
While there are many advantages to using aftermarket camshafts, there are also some drawbacks to consider:
- Potential for Reduced Fuel Economy: Increased performance may come at the cost of fuel efficiency.
- Increased Wear: More aggressive cam profiles can lead to increased wear on engine components.
- Cost: High-quality camshafts can be expensive, and installation may require professional help.
Understanding Intake Systems
Intake systems are essential for delivering air to the engine, which is crucial for combustion. Upgrading the intake system can lead to significant improvements in engine performance. Here are some important considerations:
- Types of Intake Systems: Options include cold air intakes, short ram intakes, and factory replacements.
- Airflow Improvements: Better airflow can result in increased horsepower and torque.
- Sound Enhancement: Many aftermarket intakes provide a more aggressive engine sound.
Benefits of Aftermarket Intake Systems
Aftermarket intake systems offer several advantages that can enhance engine performance:
- Increased Horsepower: A well-designed intake can significantly boost horsepower by improving airflow.
- Better Throttle Response: Enhanced air delivery can lead to quicker throttle response.
- Weight Reduction: Many aftermarket intakes are lighter than stock options, contributing to overall vehicle performance.
Drawbacks of Aftermarket Intake Systems
Despite their benefits, aftermarket intake systems can have some downsides:
- Potential for Increased Engine Noise: While some may enjoy the sound, others may find it excessive.
- Risk of Water Ingestion: Certain designs may be more susceptible to water ingestion in wet conditions.
- Installation Complexity: Some intake systems may require modifications for proper fitment.
Comparing Camshafts and Intake Systems
When considering aftermarket modifications for WRX built engines, it’s essential to compare the benefits and drawbacks of camshafts and intake systems:
- Power Gains: Both camshafts and intake systems can provide significant power gains, but they operate in different ways.
- Cost Considerations: Upgrading both components can be costly, requiring careful budgeting.
- Synergy: Using both upgrades together can lead to optimal performance, as they complement each other.
Conclusion
In conclusion, aftermarket camshafts and intake systems are vital components for maximizing power in WRX built engines. Each offers unique benefits and potential drawbacks, making it essential for enthusiasts to carefully consider their options. By understanding how these components work together, drivers can make informed decisions that will enhance their vehicle’s performance and driving experience.
