The .7 HEMI engine has gained a reputation for its robust performance and potential for significant power upgrades. In this guide, we will explore how you can boost the power of your .7 HEMI to an impressive 400-450 horsepower using turbocharger kits from renowned manufacturers Garrett and BorgWarner.
Understanding the .7 HEMI Engine
The .7 HEMI engine, known for its distinctive hemispherical combustion chamber design, offers a solid foundation for performance enhancements. With a displacement of 7.0 liters, this engine is capable of producing substantial horsepower and torque. However, to reach the 400-450 HP range, additional modifications are necessary.
Benefits of Turbocharging
Turbocharging is one of the most effective ways to increase an engine’s power output. By forcing more air into the combustion chamber, turbochargers allow for a more efficient burn of fuel, resulting in increased horsepower and torque.
- Improved power-to-weight ratio
- Increased efficiency
- Enhanced throttle response
- Potential for higher torque at lower RPMs
