The Audi RS5 is a high-performance sports coupe that has captured the hearts of enthusiasts since its debut. With its powerful engine and sleek design, it’s a vehicle that commands attention on the road. In this article, we will delve into the results of a dyno test comparing the stock performance of the Audi RS5 at 470 horsepower to its performance after an ECU remapping and intake upgrade, which pushes the power output to an impressive 530 horsepower.
Overview of the Audi RS5
The Audi RS5 is equipped with a 2.9-liter V6 twin-turbo engine, which is known for its remarkable balance of power and efficiency. The stock version produces 470 horsepower and 442 lb-ft of torque, allowing it to go from 0 to 60 mph in just 3.9 seconds. The combination of Quattro all-wheel drive and an 8-speed automatic transmission ensures that power is delivered smoothly and effectively.
Dyno Testing Methodology
To accurately measure the performance of the Audi RS5, we conducted a series of dyno tests. The testing environment was controlled to ensure consistent results. The first test was performed on the stock vehicle, followed by tests after the ECU remapping and intake upgrade. The following parameters were recorded:
- Horsepower (HP)
- Torque (lb-ft)
- Air-Fuel Ratio (AFR)
- Boost Pressure
Stock Performance Results
The initial dyno test of the stock Audi RS5 revealed the following results:
- Horsepower: 470 HP at 6,500 RPM
- Torque: 442 lb-ft at 1,900 RPM
- Air-Fuel Ratio: 12.5:1
- Boost Pressure: 19 PSI
These figures demonstrate that the stock RS5 is already a formidable performer, delivering strong power and torque across the RPM range.
ECU Remapping and Intake Upgrade
The next step in our testing involved an ECU remapping and an upgraded intake system. The remapping process recalibrates the engine’s control unit, optimizing fuel delivery and ignition timing for increased performance. The intake upgrade allows for better airflow, which further enhances engine efficiency and power output.
Performance Results After Upgrades
Following the ECU remapping and intake upgrade, the Audi RS5 was retested on the dyno with the following results:
- Horsepower: 530 HP at 6,500 RPM
- Torque: 490 lb-ft at 2,200 RPM
- Air-Fuel Ratio: 12.0:1
- Boost Pressure: 22 PSI
The increase in horsepower and torque is substantial, showcasing the effectiveness of the upgrades. The RS5 now accelerates with even greater authority, making it a more thrilling driving experience.
Comparison of Stock vs. Upgraded Performance
When comparing the stock performance to the upgraded results, the differences are clear:
- Horsepower Increase: 60 HP
- Torque Increase: 48 lb-ft
- Boost Pressure Increase: 3 PSI
This significant improvement in performance highlights the potential of the Audi RS5 when modified, making it a prime candidate for enthusiasts looking to enhance their driving experience.
Conclusion
The dyno test results clearly illustrate the benefits of ECU remapping and intake upgrades for the Audi RS5. With a jump from 470 horsepower to 530 horsepower, the modifications not only enhance performance but also elevate the driving experience to new heights. For Audi RS5 owners considering upgrades, the results speak for themselves, demonstrating that with the right modifications, this already impressive vehicle can achieve even greater performance.
