The Audi RS5 2.9TT is a high-performance vehicle that has captured the attention of car enthusiasts and tuners alike. With its twin-turbocharged V6 engine, the RS5 offers impressive power and performance straight from the factory. However, many owners seek to enhance their driving experience further with aftermarket modifications. This article explores the dyno-verified power gains achieved through the installation of a Milltek exhaust system and an APR intercooler.
Understanding the RS5 2.9TT Engine
The heart of the RS5 is its 2.9-liter twin-turbocharged V6 engine, which produces a robust 444 horsepower and 443 lb-ft of torque. This engine is known for its rapid acceleration and responsive throttle. However, with the right modifications, it can unleash even more power and improve overall performance.
Benefits of Upgrading the Exhaust System
A performance exhaust system is one of the most popular modifications for the RS5. The Milltek exhaust system is designed to enhance exhaust flow, reduce back pressure, and improve sound quality.
Power Gains from Milltek Exhaust
When tested on the dyno, the Milltek exhaust system showed significant power gains. Here are the results:
- Stock Power: 444 hp
- Milltek Exhaust Power: 470 hp
- Power Gain: 26 hp
The increase in horsepower is attributed to improved exhaust flow, which allows the engine to breathe better and produce more power.
The Role of an Intercooler in Performance
An intercooler is essential for turbocharged engines, as it cools the intake air before it enters the engine. Cooler air is denser, allowing for more oxygen to be packed into the combustion chamber, which leads to increased power.
APR Intercooler Benefits
The APR intercooler is designed to provide superior cooling efficiency compared to the stock unit. This upgrade is particularly beneficial during high-performance driving conditions.
- Stock Intercooler: Limited cooling capacity
- APR Intercooler: Enhanced cooling efficiency
- Result: Improved throttle response and power
On the dyno, the APR intercooler demonstrated impressive results, contributing to the overall performance of the RS5.
Combined Power Gains from Milltek Exhaust and APR Intercooler
When both the Milltek exhaust system and APR intercooler are installed, the results are even more remarkable. The combination of improved exhaust flow and enhanced cooling leads to significant power gains.
- Base Power: 444 hp
- Milltek Exhaust Gain: +26 hp
- APR Intercooler Gain: +20 hp
- Total Power: 490 hp
This total power output showcases the effectiveness of these modifications, making the RS5 a formidable performer on the road and track.
Conclusion
Upgrading the Audi RS5 2.9TT with a Milltek exhaust and APR intercooler provides significant dyno-verified power gains. These modifications not only enhance performance but also improve the overall driving experience. For RS5 owners looking to maximize their vehicle’s potential, these upgrades are a worthwhile investment.
