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.

Nitrous oxide tanks

How Nitrous Oxide Works in Diesel Engines

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.

Diesel particulate filter

DPF Delete dilemma

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.

Cummins heater grid

Cummins Heater Grid Delete

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.

Diesel intercooler

How Intercooling Works & Intercooler Upgrade Information

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.
