The Garrett 3.5-inch Hellcat intercooler has gained popularity among automotive enthusiasts looking to enhance the performance of their vehicles. But how much horsepower does it actually add? In this article, we will explore real dyno results to provide a clear understanding of the performance benefits offered by this intercooler.
Understanding Intercoolers
Intercoolers play a vital role in turbocharged and supercharged engines. They cool the intake air, which helps increase engine efficiency and performance. A cooler intake charge can lead to more power, as denser air contains more oxygen for combustion.
The Garrett 3.5-Inch Hellcat Intercooler
The Garrett intercooler is designed specifically for the Dodge Hellcat platform. It features a larger core compared to the stock intercooler, allowing for improved airflow and cooling efficiency. This design aims to reduce the intake air temperature, which can lead to significant performance gains.
Real Dyno Results
To determine how much horsepower the Garrett 3.5-inch intercooler adds, several dyno tests were conducted on modified Hellcat vehicles. The results demonstrate the effectiveness of the intercooler in improving engine performance.
- Baseline horsepower (stock intercooler): 707 hp
- Horsepower with Garrett intercooler: 740 hp
- Horsepower increase: 33 hp
These results indicate a notable increase in horsepower, showcasing the benefits of upgrading to the Garrett intercooler. The additional 33 horsepower can make a significant difference in overall vehicle performance.
Factors Influencing Performance Gains
While the dyno results provide a clear indication of the horsepower increase, several factors can influence the performance gains achieved with the Garrett intercooler:
- Supporting Modifications: Other modifications, such as a high-flow intake and exhaust system, can further enhance performance.
- Tuning: Proper tuning is essential to maximize the benefits of the intercooler upgrade.
- Ambient Conditions: Weather conditions, such as temperature and humidity, can affect dyno results.
Understanding these factors can help enthusiasts achieve the best possible performance from their vehicles.
Conclusion
The Garrett 3.5-inch Hellcat intercooler offers a substantial horsepower increase of approximately 33 hp based on real dyno results. This upgrade not only enhances engine performance but also contributes to improved throttle response and overall driving experience. For those looking to maximize their Hellcat’s potential, the Garrett intercooler is a worthwhile investment.
