DAP Injectors

[TFaoro]

I have a buddy with an 03 and his injectors are dying. He is looking for a good place to buy some injectors that won't destroy the bank. I told him about DAP, but we aren't sure just how good they are. Has anyone ever run DAP common rail injectors? Are they reliably and high quality? I know my 100hp 24V injectors are great, he just wants some reassurance. Thanks in advance!

I would only run bosch remans that are actually rebuilt by bosch. Dont get confusedb reman bosch. I have been seeing lots of bad remans lately and it isnt worth destroying an engine. I get mine through browns diesel

[TFaoro]

Any thoughts on these?

Ya i forgot about the smarty ones. They are well worth the extra money. Plus everything is brand new and you keep the old injectors. Im not certain about those from dap. Seem too good for a 50hp injector for only $350 each

[AH64ID]

He want's to get new ones only, they will hurt the bank a little more but will be trouble free vs many of the reman issues.

 

The BBi's are top notch, hands down. They are more money but your old ones can be sold as cores for around $600.

 

BMS are #2, and OEM are #3.

 

I would suggest getting OEM's with a minor upgrade, like 50hp. Better fuel economy and a nice increase in power as well.

I run the BMS ones with the 50HP DDP nozzles and they are a great improvent over my original stock injectors.  No smoke and a nice power increase and I have seen 22+ mpg on several trips to Portland and back.  Frm what I can tell in talking to other folks, that is great mileage for an '05 CR.

BMS ???

What about DDP and F1????  They used to be the big players in injectors.

Bosch Motor Sport.  These are marine injectors.  All brand new Bosch (no reman or reused parts).  They can be fitted with various HP nozzles and spray angles but come stock for the 385 HP cummins marine engine ( I think I have my numbers correct on this).

 

DAP usually has these as do other vendors.  I got mine from USA Freedom Diesel (Montana) with the DDP nozzles and flow tested.  I am very happy with them in my truck.

Thanks for the help guys I'll let him know what you have suggested and let him decide!

[hex0rz]

The one thing I seem to remember about the BBI's is the fact that they say they have the injector issues solved. The fact that there are multiple injection events on one stroke, they use the best and some certain type of engineering aspect that allows their injectors to be the best.

 

I'm no salesman, but if they are saying they solved the premature injector failure issue, I would be alllllll over that one!

2 micron filtration is key

[AH64ID]

The BMS 50's are the 03-04 spray pattern and come in the QSB 440's.

 

The BMS 100's are the 03-04 spray pattern and come in the QSB 480's.

 

Lots of people running 03-04 spray pattern in the 04.5-07, just don't run 04.5-07 in a 03-04.

Premature injectulation???!!!  

 

 

 

Lots of people running 03-04 spray pattern in the 04.5-07, just don't run 04.5-07 in a 03-04.

 

 

Could you expand on that some more??  How is that possible???  I always thought that it a no-no!!  

[Wild and Free]

OK I never heard of BMS then. Makes sense.

 

DW if the spray pattern of the 03-04 is narrower than the 05-07 and still hits inside the sweetspot in the cup of the piston then no issues. The issue comes when the spray patter hits outside th bowl on the top flat area that causes hot spots and torches throught the aluminum.

This is just a guess as to why it would work not knowing exactly what the pray patterns or piston cups are on them.

[AH64ID]

The 03-04 is actually flatter, wider, than the 04.5-07 but it works, and is becoming more common.

 

I am not sure I agree with it, yet, but time will tell.

There are quite a few people talking about how the flame front works, etc and apparently it works with 03-04 in 04.5+ but not the other way around.

I know quite a few people doing it, and so far I haven't seen a single issue from it. There was one possible issue on Cummins Forum but there where other issues so it's really hard to say.

[mopartechnician]

03-04 have a smaller piston bowl right? Thats why you can spot bad injectors better in a 03-04 than the newer years because it sprays on top of the piston and not in the bowl. Am I close?

[AH64ID]

Yes they have a smaller diameter bowl (all 03-07 bowls have the same cc's), and a wider spray pattern.

 

Timing is the bigger reason to spray on top of the bowl, unless there is a serious problem with the nozzle.
