Featured Diesel Performance Tech
Want to tow with more confidence? More power? Better fuel economy? These essential modifications aim to improve performance, fuel economy, handling, and trailer stopping/decent control.
By far the most popular modification on the market and best bang for the buck, tuners/programmers provide substantial increases in horsepower and torque at the push of a button. As engine management systems become more sophisticated, the aftermarket responds with even more powerful devices.
Looking to mod your 12v Cummins on a budget? Both 1st and 2nd generation 12v engines feature a mechanical injection pump with adjustments to alter various fueling characteristics that potentially may unlock measurable power for cheap.
In a nutshell, nitrous oxide injection serves as both a turbocharger and intercooler in that it injects a great deal of oxygen into the engine and provides a cooling effect upon the intake air charge.
To delete, or not to delete, that is the question. We dive into the controversial topic of deleting and disabling a diesel particulate filter system. While the obvious improvements in reliability, performance, and fuel economy are attractive benefits to a DPF delete, there are many aspects to consider before moving forward.
Who needs a heat grid? Well, some of us might, but for those who live in warmer climates it may only serve as an unnecessary restriction and deleting the heater grid on the 5.9L Cummins has been proven to allow for greater airflow potentials, albeit marginal in many instances.
The efficiency and performance potential of turbocharging is significantly increased as a result of intercooling. Sometimes also referred to as aftercooling, the process cools the hot, pressurized intake charge before it reaches the intake manifold. Intercooling can be accomplished with in air-to-air and water-to-air methods, the later requiring a more sophisticated cooling system.
Tuning the 6.9L and 7.3L IDI diesel is a fairly simple task requiring only basic hand tools, a pyrometer, and a few hours of downtime. By adjusting the fuel settings on the Stanadyne DB2 injection pump, IDI owners can find the sweet spot between maximum power and minimal smoke, which coincidentally can send EGTs skyrocketing into the danger zone.
Diesel propane injection was relatively popular when it first came to market. However, it's become a widely controversial modification with skeptics claiming the LPG/CNG injection is not ideal for the diesel cycle and proponents pointing out the potential for massive fuel savings.
