The performance of a vehicle can often be enhanced through various modifications, one of which is the camshaft swap. This article will delve into the specifics of performance camshaft swaps for Volvo 5 cylinder engines, exploring whether such modifications can genuinely increase power by 25 horsepower.
Understanding Camshafts and Their Role
Camshafts play a crucial role in controlling the timing and duration of the engine’s intake and exhaust valves. This control directly affects engine performance, efficiency, and power output. In a performance context, camshafts can be designed to allow for greater airflow, which can lead to increased power.
Volvo 5 Cylinder Engines Overview
Volvo’s 5 cylinder engines, particularly those found in the 850, S70, and V70 models, are known for their unique balance of performance and efficiency. These engines have a distinct sound and character that many enthusiasts appreciate. Understanding the specifics of these engines is essential for evaluating the impact of a camshaft swap.
Engine Specifications
The Volvo 5 cylinder engines typically feature:
- Displacement: Ranges from 2.0 to 2.5 liters
- Configuration: Inline 5 cylinder
- Fuel System: Multi-point fuel injection
- Power Output: Varies by model, generally between 140 to 250 hp
Benefits of a Performance Camshaft Swap
Swapping to a performance camshaft can provide several benefits, including:
- Increased horsepower and torque
- Improved throttle response
- Enhanced engine sound
- Better overall performance in high RPM ranges
Potential Power Gains
One of the most discussed aspects of a camshaft swap is the potential for increased power. Many enthusiasts claim that a well-chosen camshaft can yield gains of up to 25 horsepower. However, several factors influence these results.
Factors Influencing Power Gains
Several factors can affect the power gains from a camshaft swap:
- Type of camshaft selected
- Supporting modifications (exhaust, intake, tuning)
- Engine condition and maintenance
- Fuel quality used
Choosing the Right Camshaft
Selecting the right camshaft is critical for achieving desired power gains. Performance camshafts come in various profiles, each designed for specific performance characteristics.

Supporting Modifications
To maximize the benefits of a camshaft swap, supporting modifications are often necessary. These modifications can help ensure the engine can take full advantage of the new camshaft profile.
Essential Supporting Modifications
- High-flow intake system
- Performance exhaust system
- ECU tuning for optimal fuel maps
- Upgraded fuel injectors
Installation Considerations
Installing a performance camshaft requires careful consideration and precision. It’s advisable to consult with a professional mechanic or a knowledgeable enthusiast to ensure proper installation.
Installation Steps
- Remove the valve cover and timing belt
- Replace the camshaft
- Reinstall the timing belt and valve cover
- Adjust valve clearances as necessary
Tuning After Installation
After installing a new camshaft, tuning the engine is essential. This ensures that the engine runs efficiently and takes full advantage of the new camshaft’s characteristics.
Tuning Options
- ECU remapping
- Dyno tuning for precise adjustments
- Using performance chips or modules
Conclusion
In summary, a performance camshaft swap on a Volvo 5 cylinder engine can potentially increase power by 25 horsepower, but this is contingent upon various factors including the choice of camshaft, supporting modifications, and proper tuning. Enthusiasts should carefully consider these aspects to achieve the best results from their modifications.
