The Acura TL Type S is known for its performance and luxury, but enthusiasts often seek ways to enhance its capabilities further. One effective method to increase horsepower is through intake manifold porting. This article will explore how porting the intake manifold can boost airflow and potentially increase power by up to 15 horsepower.
Understanding Intake Manifold Porting
Intake manifold porting involves modifying the intake manifold to improve airflow into the engine. By smoothing out the internal surfaces and optimizing the shape of the ports, you can reduce turbulence and increase the volume of air entering the combustion chamber.
Benefits of Porting the Intake Manifold
Porting the intake manifold can provide several benefits for your Acura TL Type S, including:
- Increased Airflow: A well-ported manifold allows for a greater volume of air to enter the engine, enhancing combustion efficiency.
- Improved Throttle Response: Smoother airflow can lead to quicker throttle response, making the vehicle feel more agile.
- Higher Horsepower: Properly ported manifolds can result in a noticeable increase in horsepower, often around 15 hp.
- Better Fuel Efficiency: Enhanced airflow can lead to more efficient combustion, potentially improving fuel economy.
Tools and Materials Needed
Before you begin porting your intake manifold, gather the following tools and materials:
- Die grinder
- Porting bits
- Sandpaper (various grits)
- Cleaning supplies (solvent, brushes)
- Protective gear (gloves, goggles, mask)
- Torque wrench
- Gasket set
Step-by-Step Porting Process
1. Remove the Intake Manifold
Start by disconnecting the battery and removing any components that obstruct access to the intake manifold. Carefully detach the manifold from the engine, ensuring you keep track of all bolts and gaskets.
2. Clean the Manifold
Thoroughly clean the intake manifold to remove any dirt, oil, or residue. This step is crucial to ensure that you can see the areas that need modification clearly.
3. Identify Porting Areas
Examine the intake manifold and identify areas that require porting. Look for rough edges, obstructions, and areas that can be smoothed out or enlarged.
4. Begin Porting
Using the die grinder and porting bits, carefully begin removing material from the identified areas. Take your time and work gradually to avoid removing too much material.
5. Smooth the Ports
After achieving the desired shape, use sandpaper to smooth the surfaces of the ports. This step will help reduce turbulence and improve airflow.
6. Clean Again
Once porting is complete, clean the manifold again to remove any debris or dust created during the porting process. Ensure no particles are left that could enter the engine.
7. Reinstall the Intake Manifold
Carefully reinstall the intake manifold, using new gaskets as needed. Torque the bolts to the manufacturer’s specifications to ensure a proper seal.
Testing and Results
After completing the porting process and reinstalling the intake manifold, it’s time to test the results. Start the engine and allow it to idle, checking for any leaks or issues. Once verified, take the vehicle for a test drive to experience the improved throttle response and power.
Conclusion
Porting the intake manifold on your Acura TL Type S can be a rewarding modification that enhances performance. With the right tools and careful execution, you can achieve an increase in horsepower and overall driving experience. Always remember to follow safety precautions and consult with a professional if you’re unsure about any steps in the process.
