Additional Insight on BBi Injectors

then why are you chiming in like you would know anything about them... anyways, i have talked to people that have run industrial injection, bosh motorspots, BD diesel, DTech, Dynomite Diesel, all stateing how much smoother the bbi's are, they may not have them to expirence the performance on the road yet.. but i do and more and more people are getting into them so im sure you will see more and more good news and info soon.
 
Bumper indicates less than clean...or not washed it in 5,000mi?
 
it does have a smarty on it.. idk who runs one but no matter what you do its going to smoke with a smarty.. the injectors are 30lpm over stock so... they flow more as well.. i dont think anyone ever said they dont smoke.. i would love to see a truck making high hp with no smoke at all!!
 
So then I don't get the purpose of these...if they still smoke/haze just like "Competitors Nozzles"...then what justifies the cost?

Just for thought...except for WOT my 200hp nozzles with non-smarty tuning are smokeless.

This is a 12valve so we can't expect miracles but it's pretty close to with no smoke at all and is making just over 700 hp at the wheels. I assume this is close to the upper HP limit of those BBI stage 1's on a common rail motor. In my experience, smoke is 10% injector related and 90% tuning. Aggressive tuning designed for stock injectors will probably smoke with larger injectors. I know on my crude mechanical injection Junker Drag Truck, the fueling duration (pulse width for you electronic guys) is cut back almost 50% over stock in the lower boost ranges.

i still see smoke hen he does the pull.. anyways, my smarty is on a lower level untill i get a clutch so its just the catcher tune. once i get my clutch put in i will be able to do the udc tuning and alot of the smoke will clear up, as it is now it will smoke at low boost if im lugging it or take off hard. when i do the udc tune it will take most all of the smoke away. also, as it is now at wot i dont see mutch of any smoke from it. probly less then that 12v..

if you really do your research and look at everything BBI has put out about their injectos you will find all the info you need about what "justifies" the cost. they flow and spray better under all pressures then brand x and y whoever they may be. the BBI injectors are the most clear cut nozzles and spray the best through all the rpms and at all pressures.. they arnt just the nozzle that is different either. they build the entire injector to much better standards and tolerences then any other company.. the proof and information and testing is all out there.. do some reading and and find what the difference is.. i may not be able to prove to you with just my words and there words but testing and all the time in development does. look at some of these charts and dyno runs. i dont think this is all just made up..

the 23,200psi (1600) bar tests don't seem very balanced... Do they test to 26K?

If you look at the largest injector in that set, it flows 165.7 mm³/stroke. 2% of that is 3.314 mm³/stroke.

The smallest injector in that set flows 163.1 mm³/stroke, 2% of that is 3.262 mm³/stroke.

The flow difference between the largest & smallest injectors in that set @ 1600 bar is 2.6 mm³/stroke. Well within the BBi standard of maximum allowable difference of 2%.

Have you ever seen a chart like this on other aftermarket injectors to compare? I haven’t... I would like to see these same tests on a variety of aftermarket injectors and tips to see how they do... I think that would prove a lot… I don’t know what brand x and y in the BBI charts are but if I took a guess I would say they are some well-known brands… just my thought though.

Nah, don't have a chart like that. My 6.7 injector calibration print just shows more MPa test points at more duration points... Less than 2%. Just run of the mill crap injectors.

You mean something like this...250% overs within >1%
