The Dodge SRT-4 is known for its impressive performance and tuning potential. With the right upgrades, enthusiasts can push the limits of this compact powerhouse. This article explores how to achieve 350 wheel horsepower (WHP) using an AEM Engine Management System (EMS) and a 3.5-inch turboback exhaust system.
Understanding the SRT-4 Turbo System
The SRT-4 is equipped with a 2.4-liter turbocharged inline-four engine, which provides a solid foundation for tuning. The turbocharger, intercooler, and exhaust system are critical components that can be upgraded to enhance performance.
Stock Turbo Specifications
The stock turbocharger on the SRT-4 is a Garrett GT28, which offers a good balance of power and response. However, to reach the 350 WHP goal, a larger turbo and supporting modifications are necessary.
Essential Upgrades for 350 WHP
- AEM EMS
- 3.5-inch turboback exhaust
- Upgraded turbocharger
- High-flow fuel injectors
- Upgraded intercooler
- Performance intake system
AEM EMS Installation
The AEM EMS is a powerful engine management solution that allows for precise tuning of fuel and ignition maps. Installing the AEM EMS involves:
- Removing the stock ECU
- Wiring the AEM harness
- Configuring the EMS settings
- Uploading base maps for initial tuning
Upgrading the Exhaust System
A 3.5-inch turboback exhaust system improves exhaust flow and reduces back pressure, which is essential for achieving higher power levels. Key steps include:
- Removing the stock exhaust components
- Installing the new turboback system
- Ensuring proper fitment and sealing
Supporting Modifications
To support the increased power output, several additional modifications are necessary:
- High-flow fuel injectors to meet the increased fuel demand.
- An upgraded intercooler to reduce intake temperatures.
- A performance intake system to improve airflow.
Choosing the Right Turbocharger
To achieve 350 WHP, selecting a suitable turbocharger is crucial. Popular options include:
- Garrett GT30
- Precision 5862
- FP Black Turbo
Tuning for Maximum Performance
After completing the hardware upgrades, tuning is essential to achieve the desired power output. This process typically involves:
- Using a dynamometer to measure power output.
- Tweaking fuel and ignition maps for optimal performance.
- Monitoring air-fuel ratios to ensure engine safety.
Final Thoughts on Tuning the SRT-4
Tuning the SRT-4 for 350 WHP is an achievable goal with the right upgrades and tuning strategy. By focusing on key components like the AEM EMS and a 3.5-inch turboback exhaust, enthusiasts can unlock the full potential of their vehicles.
As always, ensure that all modifications comply with local regulations and consider consulting with a professional tuner for the best results.
