The 5.9 Cummins 24v is known for its incredible reliability, but is also well known for its performance potential. While CP3 versions of the engine are going to be the most capable, even the VP44’s can produce some decent power levels with just tuning and a few bolt on modifications. In this guide we’re going…
While the 6.7 Cummins turbo-diesel is one of the best modern power plants on the market, it is far from a perfect engine. Unfortunately, one of the biggest issues is the Holset HE351VE turbocharger and VGT actuator failure. When the actuator fails you will run into a number of performance related issues like a loss…
For over a decade now, the Ford 6.7 Powerstroke and Dodge’s 6.7 Cummins have been the top of the line for turbo-diesel power plants. Yet, besides their displacement, they actually share very little in common. For starters, the Powerstroke is a V8 while the Cummins is an inline-six. However, they are two of the most…
If you were looking for turbo-diesel power in the 1990s and early-2000s, you had two main choices: Ford’s 7.3 Powerstroke V8 or Dodge’s 5.9 Cummins I6. These were some of the first modern diesels to have direct injection and turbochargers as standard, opening up entire new worlds of performance opportunities. Though now long out of…
Crankcase ventilation systems take dirty gases and pass them back into the intake system to have them burned during combustion. While this is a positive for emissions, it is a negative when it comes to performance and engine longevity on the 6.7 Powerstroke. For these reasons, deleting the CCV system is a popular modification to…
If there is one downside to the 6.7 Powerstroke, it was Ford’s decision to use the Bosch CP4.2 high-pressure fuel pump. The CP4.2 is notorious for failing early, and it also struggles to adequately fuel past 500 horsepower. A much better option is the Bosch CP3 fuel pump. For those looking to push their builds…
When it comes to 6.7 Powerstroke performance modifications, nothing adds power like a turbocharger upgrade. Furthermore, the 2011-2014 models had an unreliable and problematic turbo, making it a great performance and reliability upgrade to swap in a new turbo. However, there are tons of routes to go and differing options based on your engine generation….
Since it first became available for the 2007 model year, the 6.7 Cummins has made a solid name for itself as one of the most powerful and dependable turbo-diesel truck engines. Over the years there have been a number of design changes and problems to be aware of, however. In this guide we are going…
Power output was decidedly modest for the 5.0 Cummins, at just 310 horsepower and 555 lb-ft of torque. Fortunately, engine tuning and some bolt-on performance mods can take this engine to the 425whp range for just a few thousand dollars. Pushing too much beyond these power levels get expensive and starts to sacrifice reliability, which…
While it has been out of production for almost two decades, the 24v 5.9L Cummins is still widely regarded as one of the best turbo-diesel engines ever made. Also known as the 5.9 ISB, the engine was the successor to the beloved 12v Cummins. Dodge produced the 24v Cummins from 1998–2007, where it made 215–325…
You don’t need a full size diesel like the 6.7 Cummins to make some serious power and torque. Just a few bolt-on performance upgrades can take the half-ton 3.0 EcoDiesel to above 300whp and 500wtq. While the 3.0 EcoDiesel has a questionable reputation from a reliability perspective, its fuel economy and factory performance make it…
The 5.9 Cummins 12v earned a legendary reputation for reliability. The engine is also extremely strong, making it a prime candidate for performance modifications and upgrades. However, these engines are mechanically driven which makes them a bit more challenging to modify. While it isn’t as simple as just dropping a tune on it, there are…
