If you own a Ram with a 6.7 Cummins engine, there are simple and affordable modifications you can easily install. These bolt-on mods can significantly boost your vehicle’s power, adding over 150 horsepower and torque to your wheels. And all that for just a few thousand dollars. You can visit racemeofficial.com to increase the performance of your dodge ram 6.7 Cummins.
However, beyond this point, achieving even greater power becomes much costlier. This is because fueling limitations start to become a problem, which then requires the installation of additional upgrades. These include things such as a high-pressure fuel pump, a lift pump, and high-flow injectors.
The good news is that you can significantly increase the performance of your 6.7 Cummins by following the below methods.
6.7 Cummins Tunes
If you’re looking to upgrade your 6.7 Cummins engine, getting a tune should be your top priority. It’s the most effective way to increase power and get the most value for your money. Adding a tune can optimize the performance of other upgrades you make to your engine. So, if you’re only adding one modification to your 6.7 Cummins, a tune is the way to go.
A tune is a modification that fine-tunes several engine parameters such as fueling and boosts to enhance the engine’s efficiency. With a plug-and-play tune, you’ll have access to several pre-built maps. It will serve different purposes, such as fuel economy, power, and towing.
Moreover, a proper tune will consider other performance modifications like intake, and adjust the engine parameters accordingly to optimize the engine’s output and efficiency. For those seeking a modest boost in engine power, a plug-and-play unit will suffice. However, if you have specific performance goals in mind, custom tuning with EFI Live is essential.
6.7 Cummins Cold Air Intake Upgrade
The second most preferred upgrade on our list is a better intake system. Tunes primarily enhance power by raising turbo boost levels. But it’s crucial to bring more air into the engine when running at higher boost levels. This will help to alleviate strain on the turbo and boost its spooling capacity. Therefore, we highly recommend installing a performance intake system to boost the airflow into the engine.
An upgraded intake system can enhance engine efficiency by improving the airflow, resulting in power gains of approximately 5-10hp and 20-30tq. This modification costs less than $400 on average and offers multiple benefits such as increased power, improved fuel efficiency, and even a slight improvement in gas mileage.
6.7 Cummins Intercooler Upgrade
The turbocharger compresses the intake air, which causes it to heat up. To prevent the heated air from entering the combustion chamber, it must be cooled down. This is achieved by passing the compressed air through an intercooler. However, the stock intercoolers in 6.7 Cummins, particularly in models produced between 2013-2018, are relatively small.
When the engine is tuned and an intake is added, more air is brought into the engine, which necessitates more cooling. Apart from improving engine reliability, a larger intercooler is a highly beneficial modification for those who tow regularly. It ensures that the engine is healthier by enabling colder air to enter and reducing Exhaust Gas Temperatures (EGTs).
The overall result is a healthier engine. Furthermore, an intercooler helps to prevent heat soaking and high EGTs while towing heavy loads.
6.7 Cummins Exhaust Upgrade
As we increase the air and boost levels in the engine, it becomes crucial to decrease the exhaust system’s restriction to enhance exhaust airflow. The addition of air and boost raises the exhaust backpressure, which hinders the turbo’s ability to spool and, consequently, adds stress to it while decreasing its efficiency.
The most effective method to decrease exhaust backpressure is by replacing the exhaust system with a 5″ upgraded system. The greatest gains will be seen in 2007.5-2010 models that lack emissions equipment. However, for 2011+ models with DPF and other emissions equipment, the gains will be less.
You have two options when it comes to replacing the exhaust system: a 4″ or 5″ system. The 5″ system will offer better flow and lower Exhaust Gas Temperatures (EGTs), but it may also require upgrading the downpipe.
6.7 Cummins Intake Horn Upgrade
The intake horn and the intake manifold refer to the same component. If you’re seeking simple bolt-on power, we suggest focusing on a tune, intake, exhaust, and intercooler and ignoring the intake manifold upgrade. However, if you’re looking to achieve more power, an upgraded intake manifold is an excellent modification.
By replacing the intake horn, you can increase airflow by 25-50% and decrease Exhaust Gas Temperatures (EGTs) by 50-100°F. This upgrade can offer a boost of around 15rwhp and 25wtq, while simultaneously enhancing the engine’s reliability through lower EGTs. Additionally, certain intake horns feature bungs for injecting methanol, nitrous, and other substances.
Final Words
If you are interested in getting these modifications, go to https://racemeofficial.com. The 6.7 Cummins already generates impressive power levels from the factory. While bolt-on modifications can provide a notable power boost, attaining significant power gains can be quite costly due to transmission and fuel constraints.
That being said, the modifications we suggest should offer ample power and performance benefits for most individuals, all without compromising reliability.
