Dyno Day Results

This past Saturday I hosted a dyno day at my shop. As this pertains to the 6.0 world I will pass along some of the 6.0 results. So what we had was basically 4 6.0 trucks that were all similar yet all slightly different. These 4 ranged from 2003 to 2005 in model year, all had headstuds, straight pipe exhaust, tuner, and stock turbos. I feel these trucks give a very good overall comparison of what different injectors do as these were all on the same dyno same day. All of these truck had stock low pressure fuel systems.

I don't have the dyno sheets in front of me so I am giving a brief overview of the results

First truck (2004 automatic) had a sct race tune, stock ficm, stock injectors made 425 rwhp.

Second truck was my old dually (2003 manual), Kem tune, Ficm tuned, I rebuilt the injectors right before I sold the guy the truck and they are stock sized, 460 rwhp.

Third truck, 2003 automatic, Innovative race tune, stock ficm, we modded the injectors to 190cc with stock nozzles (Renegade Diesel injectors), made 485 rwhp.

Fourth truck, 2005 automatic, Innovative Race tune, stock ficm, Warren 175cc with 75% nozzles made 495 rwhp.

Man I really wish the third truck would have had some 100% nozzles on its injectors.

Nate would it have made a difference? With a stock turbo so much fuel was being pulled I don't think it would have made much difference.

We have a truck with 190cc 150% nozzles and it walks away from truck #4 on the street. Ran out of time to get it on the dyno.

I dont know if it would have made a difference or not really. I just think it would have been cool to see what it could have laid down.

Nozzles make a world of a difference.

If the FICM would have been tuned in the fourth truck what would be your guess on the RWHP. I have a similar setup as the fourth truck and was thinking about getting the FICM tuned by php.

Jeremy, are there many trucks out there with 150% nozzles on 190's? Also, is there really that much advantage or big of a difference between 100% and 150% nozzles on 190's?

From what i've been told, there is a noticeable difference. Of course I have no personal experience with this size nozzles, Im just going by what i've recently talked about with various injector builders.. You're going to get the fuel out quicker and its going to provide a more efficient burn, which equals less smoke and lower egts. This is going to help spool up on the bottom end.

When my injectors get sent back to jess they're coming back 210/150s.

Some will say they're too big but, realistically, theyre 150% over STOCK, what do the stock nozzles flow? I couldn't tell you, but a 150% nozzle wont technically be inefficient like a lot of people say they will be. Im hoping to have a turbo on my truck within the next few weeks, so hopefully ill be able to get a before/after type of deal going.
