.....and if you're chasing a low injection pressure problem with a stock pump and AB/AD injectors on a "hot" tune, don't be surprised if neither pump gets your pressure where it's supposed to be.

Oil usage is determined by intensifier piston area, plunger travel, and nozzle size.
Basically, split shot injectors waste a good bit of oil because there is a period of the injection event where oil is being used but no fuel is being injected. Couple this with a relatively small volume of fuel to begin with and the excessive injection pulse width that is required to empty an AB or AD injector and you have injectors that KILL HPO. There aren't problems under normal usage to tunes <80 HP in most cases. However, tuning that maxes out the injectors' capability (100 HP or so) really begins to show shortcomings because of this issue. That's why hybrids and singles with larger nozzles are da' bomb. Hybrids have a smaller intensifier piston (basically use about 72% of the oil volume that stock injectors use per given amount of plunger travel) and larger nozzles allow a greater amount of fuel delivery in a given amount of time compared to stock nozzles. 300 RWHP with stock nozzles on stock injectors is WAY different than 300 RWHP with larger nozzles as far as the tuning is concerned.....and that USUALLY results in the ability of a HPO system to maintain pressure above and beyond what's possible with stock splits. |

I just bought this truck about a year ago and I'm still shaking it down + going thru a giant learning curve as this is my first diesel anything. The truck just went over 300K and seems to be sound but a little weak in the hp area. Didn't know about the early 99 thing till after I bought it. I had the injectors out last winter and replaced one that was questionable with a factory reman. The tags on the injectors didn't say reman on them so I'm taking it for granted that there original. So if I upgrade I should be looking at single shots?
are they noisier than double shots? and how does the idm fall into the mix? 110v vs. 220v. I was also looking at a ballbearing turbo setup from turbonetics but that's quite away down the pipline. Did I say I love my truck. Well I do. |
