The best performance upgrades for HEMI 5.7
Below we will talk about each performance part role and what it will do for your engine and will also link to the post with recommended part (in case you need it).
1. Cold air intake
If you’re looking for a way to improve the performance of your 5.7 HEMI, a cold air intake is a great option to start. A cold air intake will help your engine breathe more easily, allowing it to run cooler and produce more power. In addition, it can also improve fuel economy.
A cold air intake is a type of air intake system designed to draw in cooler air than stock air intake. This can help improve the engine’s performance and efficiency, as cooler air is denser and contains more oxygen than warm air. Cold air intakes typically consist of a large filter connected to a tube that directs the air into the engine. They are usually installed outside the car, where they can draw in cooler air from beneath the vehicle or behind the grille.
Various cold air intakes are available on the market, so you can choose the one that best fits your needs and budget. We recommend the K&N 57-Series Cold Air Intake, a high-quality intake designed to work with 5.7 HEMI engines.
2. Exhaust system
Another great way to improve the performance of your 5.7 HEMI is with an aftermarket exhaust system. A quality exhaust system will allow your engine to breathe more freely, resulting in further increased power and efficiency. In addition, a decent exhaust system will also give your car a more aggressive sound.
When choosing an exhaust system for your 5.7 HEMI, there are a few things you need to keep in mind. The first thing to consider is the type of exhaust system you want. There are three main types of exhaust systems: single exit, dual exit, and quad exit.
Single exit exhaust systems are the simplest and most affordable option. They consist of a single pipe that exits the car at the rear. Dual exit exhaust systems have two tubes that exit at the car’s back. This setup provides a more aggressive sound and better performance than a single exit system. Quad exit exhaust systems have four pipes that exit the car, two on each side. This is the most aggressive option and provides the best performance, but it is also the most expensive.
The second thing to consider when choosing an exhaust system is the material. Exhaust systems can be made from stainless steel, aluminum, or titanium. Stainless steel is the most common material and is strong and durable. Aluminum is lightweight and dissipates heat quickly, making it a good choice for high-performance applications. Titanium is the lightest and most robust material but is also the most expensive.
The third thing to consider when choosing an exhaust system is the size of the pipes. The larger the pipe diameter, the more air your engine will be able to breathe and the more power it will produce. Most exhaust systems come with either 2.5 inches or 3 inches diameter pipes. Still, some systems offer larger or smaller pipe sizes.
Once you have considered these factors, you can choose an exhaust system that best suits your needs and desires. A quality aftermarket exhaust system can significantly improve performance and sound for your 5.7 HEMI engine.
There are various exhaust systems available, so you can choose the one that best fits your demands and budget.
Adding headers can improve the performance of your HEMI 5.7 by increasing the airflow into and out of the engine. This can result in more power and better fuel economy.
Many types of headers are available on the market, and it can be challenging to determine which one is best for your vehicle. The best way to select a header is to consider your driving habits.
If you drive in a city or suburbs, you will want a header designed for low-end torque. If you drive on the highway, you will want a header designed for high-end horsepower. Selecting the wrong header can decrease your fuel economy and performance.
Another factor is the tube type; short and long tubes. Short or popularly shorty headers are an excellent option for a 5.7 HEMI Charger because they provide improved performance and sound without sacrificing ground clearance. They’re also relatively affordable, making them a popular choice for many car enthusiasts.
Long tube headers are a superb option for 5.7 HEMI Chargers. They offer even better performance and sound than shorty headers and create more torque and horsepower. But you lose some ground clearance and are expensive.
Some headers are made from mild steel, while others are made from stainless steel. Mild steel headers are less expensive, but they will rust over time. Stainless steel headers are more costly but will not rust and last longer.
Headers are available from various manufacturers, so select the best option for your needs. To get you started, here are our best headers for HEMI 5.7.
4. ECU tune
An ECU tune can significantly impact if you’re looking for a way to realize the maximum performance of your 5.7 HEMI. A quality ECU tune can provide various benefits, including increased power, improved throttle response, and enhanced fuel economy. In addition, an ECU tune can also allow you to customize the performance of your car to your specific driving style.
When it comes to choosing an ECU tune for your 5.7 HEMI, there are a few things you’ll want to keep in mind. First, you’ll need to find a reputable tuner with experience tuning the 5.7 HEMI. Next, you’ll need to decide what kind of tune you want. Several tunes are available, including street, race, and tow tunes.
Once you’ve decided on the type of tune you want, you’ll need to make sure that the tuner has a map for your specific car. Finally, you’ll need to ensure that the tuner has access to a dyno so they can properly tune your vehicle.
If you follow these steps, you’ll be sure to find the best ECU tune for your 5.7 HEMI. With a quality ECU tune, you’ll enjoy increased power, performance, improved throttle response, and enhanced fuel economy. So to get the most out of your 5.7 HEMI, an ECU tune is a great choice.
5. Throttle body spacer
A throttle body spacer is a great path to improve the performance of your 5.7 HEMI engine. A throttle body spacer will help your engine breathe more easily, allowing it to run cooler and produce more power. In addition, it can also improve fuel economy.
The price range for throttle body spacers for 5.7 HEMI engines varies depending on the quality and features of the spacer. Generally, though, throttle body spacers can be purchased for around $50 to $100. Choosing a high-quality spacer made specifically for your engine is vital to ensure that it functions properly and does not damage your vehicle.
6. Transmission cooler
A transmission cooler is a device that helps keep your transmission running cool. It does this by circulating coolant through the transmission, which helps to dissipate heat.
A transmission cooler is a significant performance upgrade for the Hemi 5.7 engine.
This is important for two reasons. First, a cooler transmission will last longer and perform better. Second, the cold temperature will help protect your engine from damage. A transmission cooler is a must-have for any vehicle with a Hemi engine.
When choosing a transmission cooler, there are a few things you need to consider. First, you need to decide what size cooler you need. The cooler depends on the size of your transmission and the power your vehicle puts out.
Second, you need to decide what type of cooler you need. There are two types of transmission coolers: air-cooled and water-cooled. Air-cooled coolers are cheaper and easier to install, but they don’t perform as well as water-cooled coolers. If you can afford it, I recommend choosing a water-cooled cooler.
Finally, you need to decide which brand of cooler to buy. Many different brands are available, so do your research and find the one that best suits your needs.
7. Cam or camshaft
Camshaft upgrade is a great way to max out your 5.7 HEMI performance. A quality cam can add power and torque across the entire RPM range, resulting in a more responsive and powerful driving experience.
There are several factors to consider when selecting a camshaft for your engine, so it’s essential to work with an experienced professional to find the best option for your vehicle.
Some key factors that will affect your choice of cam include the type of driving you do, the power goals you’re hoping to achieve, and the upgrades that have already been made to your engine. It’s also important to consider the limitations of your vehicle’s stock components – for example, if you have a stock intake and exhaust system, you’ll need a camshaft that’s compatible with those components.
Once you’ve determined what you need in a camshaft, it’s time to start shopping around. Several reputable companies offer high-quality cams for HEMI engines, so do your research and find the best option for your needs. When installing a new camshaft, it’s essential to have it professionally installed by a qualified technician – making sure all the tolerances are correct is critical for getting the best performance from your engine.
