Fuel Injectors for 1994-1998 Dodge Ram Cummins Diesel 12 Valve
Budget Builder vs. Power Driven Injectors
Our line of Budget Builder Injectors are by far our most popular line and are the perfect choice for 99% of our customers, they are built here in house on genuine BOSCH bodies and utilize a mass manufactured nozzle of our own spec. Our Power Driven Injectors are built on the same genuine BOSCH bodies but utilize a genuine BOSCH nozzle that can be ordered in either 145° or 155° spray pattern and either SAC or VCO nozzle style. Both injector lines are pop tested and balanced within an 8bar spread in each set of 6 before they ship out the door. All Power Driven Injectors are custom made and thus are much more expensive and may have extended lead times.
5-hole vs. 6-hole vs. 7 hole Injectors
Like countless others, you may be wondering what the difference is between all of the injector sizes/hole counts and surfing the internet to find the answer can often lead to more confusion. We’re here to shed some light on the matter. Per a given flow amount, an injector with a smaller hole count and larger orifice size will penetrate deeper into the piston bowl. Depending on the rpm for the application, this could be an advantage or a drawback. An injector of the same flow with a larger hole count and smaller orifice size will produce a finer spray and penetrate less deeply into the bowl, meaning that it will burn sooner at lower rpm/boost levels. The real world effects of this seem to come in the form of burn efficiency at a given rpm. At low rpm, the 7-hole better disperses fuel into the air charge which results in increased burn efficiency (more power). There is a cross-over point around 2000rpm where the deeper penetration of the 5-hole injector results in better fuel dispersion into the increasingly turbulent air charge, enabling a more complete burn which results in more power. While apparent, these differences are minimal until 3000rpm. The 5-hole style injector is by far the most common and is the best choice for most applications.
