They don't have proof that they work. But there is proof that HUGE holes don't work for a street ride, they smoke at idle. I've seen the vid of your truck and it was great, and they deff worked, but prob wouldn't be the answer for a DD. Maybe there will be a injector with more holes that flows the same but would be more suitable for street use.
iduno maybe there is one out there
I think in the coming years there will be some real advancements with injectors. We have really just hit the tip of the iceburg. Its JMO but I feel that with some time and work more holes could be the hot ticket. Maybe not the nozles that are out there now or maybe them, I don't know. But like I said I see a future of huge impovements
The reason my truck smokes at idle has little to do with injectors.
I can make the haze go away by using more pressure but I have to make my PW so small my balance rates go to heck and it idles like crap. Now if I use low pressure 4000 and a 450 PW it idles super smooth. Smoother than my LBZ. But it hazes.
Why I think it hazes
1 15:1 compression
2 Poor quench area
3 Cam design
4 BF injectors.
I have low compression due to widen bowls and large valve releifs. The valve releifs are needed for clearence with the cam I run and they are not small. This messes up the quench area. My cam is designed to spool a large single turbo. It is actually a good bit different then a stock cam and it's design does not lend itself well to a clean idle. Last the big friken injectors. They are meant for one thing getting the fuel in fast. I am all about running lots of rpm. The FICM is much happier running the lower duty cycle and I beleive my pistons are much happier that I am not spraying them as much going down as I am with them coming up. My top PW is 60% what it was with the stockers and it never ever ran this hard before.
FWIW I think that if I had stock cam and 16:1 compression there would be no haze. One thing I really want to do is have Fingers log my idle cylinder pressure so it can be compared to a stock LB7/LLY and stock LBZ/LMM. We know the LBZ/LMM has less pressure at idle. I bet my 15:1 is a fair bit lower yet.
I have had great luck with 45% overs in stock compression trucks not smoking at idle with even no tuning change. I now of one person running 60% overs with no idle haze
there is enough proof out there, just listen to the right ones
29% overs are 10 holes, stock diameter ....
Well that all sounds great but no offense every one I know of that tried more hole injectors weather it yours, II, ATS or JL none reported good results. I messed with II 10 holes. They sucked IMHO. I keep getting told I am doing it wrong. Well I guess everyone else is doing it wrong to? You have a Dmax and EFI Live so show us. Theroy is wonderful. Your theroy makes sense but in real life it just does not seem to pan out.
More holes is far far from new by the way. I find it funny that some think this is new cutting edge stuff. Truth is Tractor pullers messed with it long ago. They told what I say. Smooth but smokey and no real gains where had unless timing was increased.
As time goes on the more I find that as far as performance goes the tractor guy know there stuff. We have better control of injection but that does not change the fact of life that it is still a direct injected diesel. Nothing new. Not a revolution more like evolution.
When Wade had his truck at the dyno a few weeks ago, I was asking him about his injectors. He wasn't sure exactly what % over they were, but he said he had a flow chart from before and after and the flow was double what it was stock. The funny thing is the thing didn't even so much as have a light whisp of smoke at idle. Of course the Custom Auto truck, which was at the track just a few weeks before, has the same injectors, and that truck was hazing really bad at idle. Maybe it's hit or miss with honed tips?
If I had to guess the shop truck has less compression. Wade's truck is 16:1 IIRC. If the shop truck is 15:1 it will make a big difference IMHO.
