If a 3.7 L V6 Engine Makes 330 Horsepower Alone, How Much Would It Make If You Add in Twin Turbos?

Rate this post

Have you ever wondered how to squeeze more power out of your car’s engine? If you’re a car enthusiast, the thought of increasing horsepower might have crossed your mind. One popular method to achieve this is by adding twin turbos to your engine. In this article, we will explore the impact of twin turbos on a 3.7 L V6 engine that already produces 330 horsepower. So, if you’re curious to know just how much power can be gained from this modification, keep reading!

Understanding Twin Turbos

Twin turbos, also known as twin turbochargers, are a forced induction system that can significantly boost an engine’s performance. They work by compressing the incoming air before it enters the engine, allowing for more air to enter the combustion chamber. This increased air intake results in improved fuel combustion and, consequently, higher horsepower output.

Adding twin turbos to a 3.7 L V6 engine can provide substantial benefits. By forcing more air into the engine, the combustion process becomes more efficient, leading to increased power and torque. Additionally, twin turbos offer quicker throttle response, which enhances the overall driving experience.

Turbocharging a 3.7 L V6 Engine

To incorporate twin turbos into a 3.7 L V6 engine, several modifications are necessary. The process typically involves installing two turbochargers, each connected to three cylinders of the V6 engine. This configuration ensures that each turbocharger has equal exhaust gas flow, resulting in balanced power delivery. Additionally, a new intake manifold, intercooler, and exhaust system may be required to support the increased airflow and exhaust gas volume.

After successfully turbocharging a 3.7 L V6 engine, the additional power gains can be significant. While the exact horsepower increase will depend on various factors, it’s not uncommon to see gains of 50% or more. This means that the 330 horsepower produced by the naturally aspirated engine could potentially reach 495 horsepower or more with the addition of twin turbos.

Factors Affecting Horsepower Increase

Several factors can influence the horsepower increase achieved by adding twin turbos to a 3.7 L V6 engine. Firstly, the overall condition of the engine plays a crucial role. A well-maintained engine with good compression and minimal wear will be better suited to handle the increased stress of forced induction.

The size and efficiency of the turbochargers also impact the horsepower gain. Larger turbos can deliver more airflow, resulting in higher horsepower potential. However, it’s essential to strike a balance between turbo size and response. Choosing the right turbochargers for your application is crucial in maximizing performance.

Engine tuning is another critical factor. Properly tuning the engine’s fuel delivery, ignition timing, and boost levels ensures optimal performance and reliability. A skilled tuner can help achieve the desired horsepower increase while maintaining the engine’s longevity.

Supporting modifications, such as upgrading the fuel system, intercooler, and exhaust, can further enhance the turbocharged engine’s performance. These modifications ensure that the increased airflow and exhaust gas volume are managed efficiently, leading to improved power output.

FAQ (Frequently Asked Questions)

Q: Will adding twin turbos affect fuel efficiency?

A: Turbocharging a 3.7 L V6 engine can impact fuel efficiency. While a turbocharged engine generally consumes more fuel under heavy load or when boosting, advancements in turbocharger technology have made significant improvements in fuel economy during normal driving conditions. However, it’s important to note that aggressive driving habits can still affect fuel efficiency.

Q: Is it necessary to upgrade other components when adding twin turbos?

A: Upgrading certain components is often necessary when adding twin turbos to a 3.7 L V6 engine. This includes upgrading the fuel system to ensure an adequate supply of fuel, upgrading the intercooler to cool the compressed air before it enters the engine, and upgrading the exhaust system to handle the increased exhaust gas volume. These modifications ensure optimal performance and longevity of the turbocharged setup.


In conclusion, adding twin turbos to a 3.7 L V6 engine that already produces 330 horsepower can result in a significant increase in power. With the right modifications, tuning, and supporting components, it’s possible to achieve gains of 50% or more. The addition of twin turbos not only improves horsepower but also enhances throttle response and overall driving experience.

If you’re looking to unleash the true potential of your 3.7 L V6 engine, turbocharging with twin turbos is a compelling option. However, it’s important to consider the factors mentioned in this article and consult with professionals who can guide you through the process. So, why settle for the ordinary when you can experience the thrill of increased horsepower with twin turbos?
