I don't believe anyone even hinted towards the idea that Bosch only tested 1 injector so idk why you even mention that

Are you speaking from experience? Do you have data or info to support your claim that pop pressure won't be very noticeable? If no, then can I ask again why you're so hesitant to learn more and get more data and real results on the topic?

I've seen VP pump 12v's, and AGCO Sisu Power engines with VP44's that run a different injector....


I'm not saying that this conversation isn't interesting, but I feel like I've seen it before in about 2006 when VP's weren't quite yet the red headed step child of the Cummins world yet...

Carry on
Chris

The density of some here seems to be increasing as this conversation moves forward. I would second the question posted earlier and ask from those of you against the idea, what are you gaining by throwing jabs, what has it gained you so far, and what do you suspect will come of the opposition?

One opacity graph from an emissions test and a good bit of hearsay. We respect results that have been paid for by those who regard this information as their business, but with that said, we who are testing this are also paying for this out of our own pockets and trying to bring information to an area that has always been kept under lock and key.

If you don’t like it then that’s your stance and that’s fine. There’s no need to be offended by the data, videos, and experience. No one is forcing anyone here to take this as the truth.

touchy touchy bunch in here..if yer gonna post data be prepared to answer questions and explain..i only ask for things to be explained so I can understand them...

the reason I mentioned the one inj use was because we were talking about larger inj not beng tested in this engine by bosch.

do you think that this is increasing or shortening duration? or no effect at all? as I would assume it must delay the inj cycle right?

I have tough skin.


So we have rough data to compare in regards to duration, Idle state, in gear, shows ~%2 duration loss at 330 bar, 55 mph cruise state shows ~%2 duration loss as well. I would say roughly %2 is a good guess.

without a doubt it is shortening the length of injection.

Is that's about when SAC and micro blinds was the new king on the street and VCOs were stock garbage.

Excellent!

Yeah, I think so...Shortly after Don M posted his findings on that ridiculous 14 hole injector that made the internets explode for a month...


I'm just saying, not that things definitely haven't progressed in 10 years, but your injector is hardly the final place for gains on a VP truck. Lots of other variables and places for much more gains and losses vs a decent quality, "over the counter" VP fire stick.

IMHO,
Chris

No but it is one that is being presented at this testing and time. Im sure it wouldn't be debated that other factors are to play into this. Ive seen just a VP swap produce better HP..

Arent builders coming back to vco nozzle these days? Curious.


Really this testing is to figure what higher pop does and present with data. Not looking to reinvent the VP world. It's a dead market.

I'm eager to read the updates, just seems like you're overly excited about what you've got so far. For me, if the improvement is miniscule, why risk shortening the life of fuel system that's already considered iffy by many. For me, my current thoughts are to go to a higher quality injector, hopefully a second turbo, and ideally get the v2 tuning to dial it in best I can.
