The 5.7 HEMI engine is one of the most powerful engines offered by Chrysler, Dodge, and Jeep. With up to 392 horsepower and 410 lb-ft of torque, it’s a powerhouse no matter your driving needs. If you’re looking to elevate your 5.7 HEMI’s performance and speed, you’re in the right spot! In this article, we’ll cover all the basics of how to make a 5.7 HEMI faster so that you can get out on the road with more power than ever before. We’ll discuss various upgrades like intakes, exhausts, programmers/tuners, superchargers/turbochargers, and more so you can customize your ride according to your specific performance goals. So, if you’re ready for an adrenaline-filled ride with extra power under the hood, read on as we dive into how to make a 5.7 HEMI faster!
Upgrading Your Air Intake System
One of the most popular and cost-effective ways to increase power in any vehicle is to upgrade the air intake system. Enhancing airflow can greatly boost engine performance. The key to upgrading your air intake system is ensuring it flows more freely than the factory setup. It can be done by replacing the stock components with higher quality aftermarket parts or adding an aftermarket cold air intake kit. Colder, denser air has more oxygen, which helps create a richer fuel/air mixture for improved combustion and more power. An upgraded air intake will also reduce engine temperature and extend engine life. Read here about Best Cold Air Intake For Jeep.
Exhaust System Upgrades
Another way to unlock more power from your 5.7 HEMI engine is through exhaust system modifications. Exhaust systems act as a pathway for burned fuel and exhaust gases to escape the combustion chamber after they have been used to create energy while powering your vehicle forward. An upgraded exhaust system will allow these gases and fuel to flow out faster, resulting in increased horsepower, torque, and acceleration due to reduced back pressure on the engine and improved airflow efficiency throughout all cylinders. Common upgrades include increasing pipe size, using low-restriction mufflers or headers, or installing a complete cat-back exhaust kit designed specifically for your vehicle’s make and model year.

ECU Tuning
To maximize your 5.7 HEMI’s performance, you must get the most out of the engine’s electronic control unit. ECU tuning is the process of reprogramming your vehicle’s computer to optimize its performance based on your specific needs. You can increase horsepower and torque levels while improving acceleration and responsiveness by adjusting various parameters such as fuel injection timing, air/fuel mixtures, and rev limits. ECU tuning can also help improve gas mileage by properly calibrating the air/fuel mixture for optimal efficiency.
Forced Induction Systems
For those looking for serious power increases, forced induction systems are one way to get there quickly and efficiently. Forced induction systems work by compressing air into the engine via either a turbocharger or supercharger, which helps create a denser fuel/air mixture that leads to increased horsepower and torque output. Turbochargers use exhaust gases from the engine to spin a turbine that forces air into the intake manifold, while superchargers are mechanical devices powered by a belt connected to your crankshaft that directly pumps air into cylinders. Either option will give you significantly more power than stock levels, but make sure you know what setup is needed for proper installation on your 5.7 HEMI before making any major decisions about forced induction upgrades.
Final Thoughts
No matter what you’re looking for in terms of performance, there are ways to increase the power output of your 5.7 HEMI engine. From simple upgrades like intakes and exhausts to more complex modifications like ECU tuning and forced induction, you can achieve higher levels of speed and efficiency with the right upgrades. Use this guide as a starting point for unlocking the power of your 5.7 HEMI engine but remember that it’s important to do your research and consult a professional before making any major changes to ensure maximum safety and reliability. Good luck!
