Dynomite Diesel Injector Horsepower Ratings and Applications


When deciding what injectors to install in your diesel pickup, the choices are sometimes overwhelming.  Hopefully with this reference guide we can help explain why we recommend installing Dynomite Diesel injectors if your are going upgrade to a larger size.  Also, if you click on the engine below, we can tell you what size diesel injector is best for your application or power level.

Benefits of Dynomite Diesel Injectors:

- Smooth and Quiet Idle

- Better Mileage

- Less Smoke

- Lower EGT's

- More Power

- Reliability

How are Dynomite Diesel Injectors different from other aftermarket injectors?

Electro Discharge Machining (EDM) is a process in which an electrically charged wire burns a hole through metal.  Nearly all OEM nozzles are manufactured using an EDM process.  From the factory they are manufactured on a very advanced machine that controls the angle and speed of the wire insertion. The angle of insertion must be measured and implemented VERY accurately or the spay angle will be changed, resulting in possible engine damage.

When the OEM manufacturer changes the speed of insertion, they can achieve a cone-shaped hole that will improve atomization. EDM’s that are used in the aftermarket are usually decommissioned medical instruments that do not have the ability to control either angle or speed precisely enough to create a quality product.  When a nozzle is manufactured by the OEM supplier not only do they EDM but they follow that up with a process called Abrasive Flow Machining which cleans up any imperfections, removes burn residue, and balances out the nozzle flow.

When our competition uses an aftermarket EDM machine, they do not use AFM to balance out the flow of the nozzle or clean up any imperfections. DDP Injectors use Hone technology. We start with an OEM nozzle or nozzle that's been specifically machined for us with the desired spray angle.  Then we go through and finish hone them to remove imperfections, polish the inside of the nozzle, and radius the inside of the holes where the fuel flows through. This leads to better atomization, which provides less smoke, less heat, more power, and improved fuel economy compared to our competition's same sized nozzle.  Adding volume without helping atomization only adds heat and smoke, which means less useable power.

Why hone each nozzle separately?

DDP Hones each nozzle separately and balances their flow to better than factory specs to create a smooth idle, and smoother running truck throughout the RPM range. Stock injector nozzles from the OEM manufacturers are usually within 2 to 3 liters per minute on a flow test machine. When any set of nozzles leaves DDP, there will be no greater than a 1 liter per minute variance from the highest flowing to the lowest.

What else should I buy with injectors?

All trucks that receive injectors should have at minimum, a pyrometer installed to monitor exhaust gas temperature.  If you click on the link below for your application, each stage of injector is listed with the required supporting modifications.
