As a result, it will transfer power to the rear tires more efficiently. It will increase not only your engine’s power output but also the torque available.how to get more power out of a 5.7 hemi

Replacing the massive iron drive shaft with a lightweight aluminum one is a good idea.

If a vehicle has a horsepower less than 900, an aluminum driveshaft allows it to spin the driveshaft with a reduced horsepower.

As a result, the engine can transfer more power to the rear wheel, increasing torque and power. Since the 5.7 Hemi engine fulfills
who criteria, this modification is an excellent choice for it.how to get more power out of a 5.7 hemi

The 5.7 Hemi engine is a computerized one, and an ECU controls it. Like all other computer systems, the electronic control unit has some restrictions as well.

The developers have put them there. You can remove those limiters by flashing the ECU. By doing so, you can take advantage of the restricted horsepower.

vehicular to increase its power output and efficiency.how to get more power out of a 5.7 hemi

If you replace the stock air filter and intake box
through an aftermarket part, it will eliminate the intake box’s need.

Instead, it will collect cooler air from the inner fender well
via an oversized air filter. Thus, the engine will get a supply of cooler air. With a large amount of cold air, the combustion chamber’s efficiency will increase radically.

You can also add a throttle body with a broader throttle body. That way, the engine can get this higher airflow without any hindrance. By doing so, you can gain a significant increase in your horsepower.how to get more power out of a 5.7 hemi

A throttle body spacer can help direct the engine’s airflow. Placed between the throttle body, the spacer can increase the volume of the space between the throttle body and the intake runners.

It will, in turn, allow more air to the engine. And we all know that the more the air, the better the combustion. Although the throttle body spacer is supposed to help provide better fuel automization, it depends on the engine’s build.

With an increase in the engine’s airflow, the throttle body spacer helps your engine bring out more horsepower.how to get more power out of a 5.7 hemi
