The B8 S4 has long been celebrated for its performance and tuning potential. Recently, we conducted a dyno test after installing an Injen intake and Unitronic software, and the results were impressive, showcasing a significant boost in power and torque. This article delves into the specifics of these modifications and the resulting performance metrics.
Understanding the B8 S4
The B8 S4, produced by Audi, features a supercharged 3.0-liter V6 engine that has garnered attention for its balance of power and efficiency. With the right modifications, the potential for increased performance is substantial. The combination of an upgraded intake system and optimized software tuning can significantly enhance engine output.
Modifications Overview
Two key modifications were made to the B8 S4 for this dyno test: the Injen intake system and Unitronic software tuning. Below, we explore each modification in detail.
Injen Intake System
The Injen intake system is designed to improve airflow to the engine, resulting in better combustion and increased horsepower. This cold air intake replaces the factory unit and is engineered to provide a substantial increase in air volume and velocity.
- Enhanced airflow for better engine performance
- High-quality materials for durability
- Improved throttle response
Unitronic Software Tuning
Unitronic software tuning optimizes the engine’s performance by adjusting the fuel maps, ignition timing, and boost levels. This tuning is specifically tailored to work with the Injen intake, ensuring that the engine runs efficiently at higher power levels.
- Increased horsepower and torque output
- Smoother power delivery
- Custom tuning for individual vehicle specifications
Dyno Results
After completing the modifications, the B8 S4 was put on the dyno to measure its performance. The results were remarkable, with the vehicle producing 370 horsepower and 390 lb-ft of torque. This marked a significant improvement over the stock figures.
Stock vs. Modified Performance
To put the results in perspective, it is essential to compare the stock performance of the B8 S4 with the modified version. The stock B8 S4 typically produces around 333 horsepower and 325 lb-ft of torque.
- Stock B8 S4: 333 hp, 325 lb-ft tq
- Modified B8 S4: 370 hp, 390 lb-ft tq
Implications of the Results
The increase in horsepower and torque not only enhances the driving experience but also improves the vehicle’s overall performance metrics. This boost allows for quicker acceleration and a more responsive throttle, making the B8 S4 a more thrilling car to drive.
Driving Experience
With the new intake and software, drivers can expect a noticeable difference in how the car performs. The added power translates to improved acceleration and a more engaging driving experience, especially during spirited driving or track days.
Conclusion
The combination of the Injen intake and Unitronic software has proven to be a successful upgrade for the B8 S4, resulting in impressive dyno numbers of 370 hp and 390 tq. These modifications not only enhance the vehicle’s performance but also provide a more enjoyable driving experience. For enthusiasts looking to unlock the full potential of their B8 S4, these upgrades are worth considering.
