The Acura TL is a well-regarded luxury sedan that combines performance with comfort. One of the most effective ways to enhance its performance is through the installation of performance camshafts. This article will explore how performance camshafts increase power and what you can expect in terms of cost and installation.
Understanding Camshafts
Camshafts play a crucial role in the engine’s operation. They control the timing and duration of the opening and closing of the engine’s valves, which directly affects performance. Performance camshafts are designed to optimize this process, allowing for greater airflow and improved engine efficiency.
How Performance Camshafts Increase Power
Performance camshafts enhance engine power through several mechanisms:
- Increased Valve Lift: Performance camshafts typically have a higher lift than stock camshafts, allowing more air and fuel to enter the combustion chamber.
- Longer Duration: They also have a longer duration, which keeps the valves open longer, improving the engine’s breathing capability.
- Better Timing: Performance camshafts can be designed for optimal timing, ensuring that the valves open and close at the most effective moments during the engine cycle.
- Improved Torque and Horsepower: By optimizing airflow and combustion efficiency, performance camshafts can significantly increase both torque and horsepower.
Types of Performance Camshafts
There are various types of performance camshafts available for the Acura TL, each designed for specific performance goals:
- Stage 1 Camshafts: Ideal for daily drivers looking for a slight increase in power without sacrificing drivability.
- Stage 2 Camshafts: Suitable for enthusiasts who want a more aggressive performance boost, often requiring supporting modifications.
- Stage 3 Camshafts: Designed for track use, these camshafts provide maximum power but may compromise everyday usability.
Cost of Performance Camshafts
The cost of performance camshafts can vary widely based on brand, type, and the specific model of the Acura TL. On average, you can expect to pay:
- $300 – $800: For the camshaft itself, depending on the performance level and brand.
- $500 – $1,500: For installation costs, which can vary based on labor rates and any additional modifications needed.
Installation Process
Installing performance camshafts is a complex process that typically involves the following steps:
- Preparation: Disconnect the battery and remove necessary components such as the intake manifold and valve covers.
- Camshaft Removal: Remove the old camshaft, taking care to note the timing and positioning of components.
- Camshaft Installation: Install the new performance camshaft, ensuring proper alignment and timing.
- Reassembly: Reassemble all components in the reverse order of removal, ensuring that all connections are secure.
- Tuning: After installation, it is often necessary to tune the engine for optimal performance with the new camshaft.
What to Expect After Installation
After installing performance camshafts, you can expect several changes in your Acura TL:
- Improved Acceleration: You will likely notice a significant increase in throttle response and acceleration.
- Increased Power Band: Performance camshafts can widen the power band, allowing for better performance across a range of RPMs.
- Engine Sound: The engine may produce a more aggressive sound, which many enthusiasts find appealing.
- Potential Fuel Economy Changes: Depending on driving habits, fuel economy may improve or decrease; tuning can help optimize this.
Conclusion
Upgrading to performance camshafts is an excellent way to enhance the power and performance of your Acura TL. While there are costs and installation considerations, the benefits in terms of performance can be significant. Whether you are a daily driver or a performance enthusiast, investing in quality camshafts can lead to an exhilarating driving experience.
