When it comes to enhancing vehicle performance, one of the most popular modifications is upgrading the air intake system. This article explores the differences between cold air intakes and short ram intakes through dyno testing, focusing on power gains and cost comparison.
Understanding Air Intake Systems
Air intake systems play a crucial role in how efficiently an engine breathes. By improving airflow, these systems can significantly impact engine performance. There are two primary types of intakes: cold air intakes and short ram intakes.
Cold Air Intake vs. Short Ram Intake
Both cold air and short ram intakes aim to improve engine performance, but they operate on different principles and have unique advantages and disadvantages.
Cold Air Intake
A cold air intake draws air from outside the engine bay, where temperatures are cooler. This cooler air is denser and contains more oxygen, which can lead to improved combustion and power output.
- Advantages: Increased horsepower and torque, better fuel efficiency, improved throttle response.
- Disadvantages: More complex installation, potential for water ingestion in extreme conditions.
Short Ram Intake
A short ram intake is designed to bring air from within the engine bay, providing a shorter path for air to travel. This can lead to quicker throttle response but may not be as effective in terms of overall power gains as a cold air intake.
- Advantages: Easier installation, quicker throttle response, often less expensive.
- Disadvantages: Higher intake temperatures, potentially less power gain compared to cold air intakes.
Dyno Testing Methodology
To accurately compare the performance of cold air intakes and short ram intakes, dyno testing was conducted on a controlled environment. The same vehicle was used for both tests to ensure consistency in results.
- Vehicle Used: 2020 Honda Civic Si
- Baseline Dyno Runs: Conducted with the stock intake system
- Testing Conditions: Same temperature, humidity, and altitude for both tests
Results of Dyno Testing
The results from the dyno testing provided clear insights into the performance differences between the two intake systems.
Cold Air Intake Results
The cold air intake demonstrated significant power gains during the testing phase. The following results were recorded:
- Horsepower Gain: 12 HP increase over stock
- Torque Gain: 10 lb-ft increase over stock
Short Ram Intake Results
The short ram intake showed moderate improvements, but not as substantial as the cold air intake. The results were as follows:
- Horsepower Gain: 6 HP increase over stock
- Torque Gain: 5 lb-ft increase over stock
Cost Comparison
When considering modifications, cost is always a significant factor. Below is a comparison of the costs associated with both intake systems.
- Cold Air Intake: Typically ranges from $200 to $400
- Short Ram Intake: Typically ranges from $100 to $250
Conclusion
In conclusion, both cold air intakes and short ram intakes offer unique benefits and drawbacks. Cold air intakes generally provide more significant power gains, while short ram intakes are often easier and cheaper to install. Ultimately, the choice between the two will depend on individual preferences and performance goals.
