The 5.9 Magnum is a V8 engine that was produced by Chrysler from 1992 to 2003. It was available in a variety of vehicles, including the Dodge Ram, Jeep Grand Cherokee, and Chrysler 300. The 5.9 Magnum is a powerful engine, but it can be made even more powerful with a few modifications.

In this article, we will discuss some of the best ways to get more horsepower out of a 5.9 Magnum. We will cover engine modifications, exhaust modifications, and other performance upgrades.

Engine Modifications

The most effective way to increase horsepower in a 5.9 Magnum is to make modifications to the engine. Some of the most common engine modifications include:

• Intake manifold: The intake manifold is responsible for delivering air to the engine. A performance intake manifold can increase airflow, which can lead to more power.
• Headers: Headers are exhaust pipes that connect the engine to the exhaust manifold. Headers can increase airflow and power, and they can also improve throttle response.
• Camshaft: The camshaft controls the opening and closing of the valves. A performance camshaft can increase valve lift and duration, which can lead to more power.
• Pistons and rods: Pistons and rods are responsible for transferring power from the crankshaft to the wheels. Upgrading to a set of high-performance pistons and rods can help to improve performance.
• ECU tuning: The ECU (electronic control unit) is the computer that controls the engine. ECU tuning can be used to adjust the engine’s performance, and it can help to improve horsepower and torque.

Exhaust Modifications

Exhaust modifications can also be used to increase horsepower in a 5.9 Magnum. Some of the most common exhaust modifications include:

• Cat-back exhaust: A cat-back exhaust is an exhaust system that replaces the catalytic converter and the rest of the exhaust system. A cat-back exhaust can increase exhaust flow, which can lead to more power.
• Downpipe: A downpipe is a section of exhaust pipe that connects the turbocharger to the rest of the exhaust system. A downpipe can increase exhaust flow and power, and it can also improve throttle response.
• Mufflers: Mufflers are used to reduce noise from the exhaust system. However, they can also restrict exhaust flow, which can reduce power. If you are looking to increase horsepower, you may want to consider removing the mufflers or replacing them with a set of performance mufflers.

Other Performance Upgrades

In addition to engine and exhaust modifications, there are a number of other performance upgrades that can be made to a 5.9 Magnum. Some of the most common performance upgrades include:

• Upgraded fuel injectors: Upgraded fuel injectors can deliver more fuel to the engine, which can lead to more power.
• Upgraded spark plugs: Upgraded spark plugs can help to improve combustion, which can lead to more power.
• Cold air intake: A cold air intake can deliver cooler air to the engine, which can lead to more power.
• Upgraded transmission: An upgraded transmission can handle more power and torque, which can improve performance.

By making a few modifications to your 5.9 Magnum, you can significantly increase its horsepower and performance. With a little bit of work, you can turn your 5.9 Magnum into a real powerhouse.

3. Drivetrain Modifications

The drivetrain is responsible for transferring power from the engine to the wheels. There are a number of modifications that can be made to improve the performance of the drivetrain and increase horsepower.

• Transmission

The transmission is responsible for converting the engine’s rotational power into torque that can be used to turn the wheels. There are a number of ways to improve the performance of a transmission, including:

• Upgrading to a higher-performance transmission
• Installing a performance clutch
• Adding a transmission cooler

• Clutch

The clutch is responsible for engaging and disengaging the transmission from the engine. A performance clutch can help to improve shifting and acceleration.

• Rear end

The rear end is responsible for transferring power from the transmission to the rear wheels. A performance rear end can help to improve acceleration and handling.

4. Suspension Modifications

The suspension is responsible for providing a smooth ride and handling. There are a number of modifications that can be made to improve the performance of the suspension, including:

• Springs

The springs are responsible for absorbing bumps and providing a smooth ride. Upgrading to stiffer springs can improve handling and reduce body roll.

• Shocks

The shocks are responsible for damping the movement of the springs. Upgrading to performance shocks can improve handling and reduce body roll.

• Struts

Struts are a type of shock absorber that is used on front-wheel drive vehicles. Upgrading to performance struts can improve handling and reduce body roll.

• Camber arms

Camber arms are used to adjust the camber of the wheels. Adjusting the camber can improve handling and reduce tire wear.

These are just a few of the modifications that can be made to a 5.9 Magnum to improve horsepower and performance. By making these modifications, you can transform your 5.9 Magnum into a powerful and capable street machine.

How To Get More Horsepower Out Of A 5.9 Magnum?

• Q: What are the best ways to increase horsepower on a 5.9 Magnum?

A: There are a number of ways to increase horsepower on a 5.9 Magnum, including:

• Increasing the displacement: The easiest way to increase horsepower is to increase the displacement of the engine. This can be done by boring out the cylinders or by adding a stroker kit.
• Adding forced induction: Forced induction, such as a supercharger or turbocharger, can also be used to increase horsepower. This works by compressing the air before it enters the engine, which allows more air to be drawn into the cylinders and burned.
• Upgrading the camshaft: A higher-lift camshaft can increase horsepower by allowing the valves to open wider and stay open longer. This allows more air and fuel to be drawn into the cylinders and burned.
• Adding performance headers: Performance headers can help to increase horsepower by reducing exhaust restriction. This allows exhaust gases to flow more freely out of the engine, which helps to improve performance.
• Installing a cold air intake: A cold air intake can help to increase horsepower by providing the engine with cooler, denser air. This air is more conducive to combustion and can help to produce more power.
• Reprogramming the ECU: Reprogramming the ECU can help to improve the engine’s performance by changing the fuel and spark maps. This can allow the engine to run more efficiently and produce more power.

• Q: How much horsepower can I expect to gain from each of these modifications?

A: The amount of horsepower you can gain from each of these modifications will vary depending on the specific engine and the other modifications that are already installed. However, you can generally expect to gain between 10 and 30 horsepower from each of these modifications.

• Q: What are the drawbacks of each of these modifications?

A: Each of these modifications has its own drawbacks. For example, increasing the displacement of the engine will increase fuel consumption. Adding forced induction can also increase fuel consumption and can put more stress on the engine. Upgrading the camshaft can make the engine more noisy. Adding performance headers can increase exhaust noise. Installing a cold air intake can decrease engine longevity. Reprogramming the ECU can void the factory warranty.

• Q: Which of these modifications are the most cost-effective?

A: The most cost-effective way to increase horsepower on a 5.9 Magnum is to upgrade the camshaft. This modification can typically be done for under $500 and can produce a noticeable increase in horsepower.

• Q: Which of these modifications are the most difficult to install?

A: The most difficult modification to install is adding forced induction. This modification requires a significant amount of engine work and should only be performed by a qualified technician.
