Their full 2014 catalog is available @ bosch-motorsport.com

Anything not listed, they state to inquire about.

I did find a PDF that gives some part numbers, the highest flowing injector they show is 697g/1016cm3 with a part number of B 280 436 469-01. I have included a copy of the PDF that has this info.

yea after some more digging, that is the general complaint about them and they are hard to come by also.

these EV14s are supposedly good for 8bar though so I guess just up the pressure till the small injector flows like big brother and reap the benefits of better atomization. A Bosch pump in their catalog capable of doing this is a mere 3-4grand easy..lol

I might have some "insider" info soon, I did inquire about some part numbers.

Comes out that all of the injector modifiers have zero clue of what they're doing, they just drill straight through ruining orignal geometry of injector or at best giving you inconsistent split cones . I ordered a set of 8 of these (on national backorder though, figures, until may 5th or something like that) and I will drill them myself with proper angles. Then test flow, I have enough parts lying around for this to be no problem.

Drilling:
- Adjustable angle drill press with precision bits, I have some nice ones that are as thin as a hair and up from there.
- I can only adjust one angle... how do I get a compound angle for both x and y so that I can accomplish both dual-cone with a bend to streams? I will have to think about this.

Test rig I am thinking about:
- stock fuel pump pumping distilled water into stock fuel manifold with 3bar fpr, return to the same bucket
- injectors in stock fuel rail dumping into 2L empty coke bottles (weight the bottles on jewelers scale pre and post test to ensure injectors are flow matched)
- injectors connected to button switch so that they all fire simultaneously when I apply 12V
- estimate new flow by testing a sample drilled injector in parallel with stock which I know how much it flows. If stock flows 200g of water per test time and the drill out does 400g I know I have 2 x stock flow (630ish cc in this case)
- once I get one injector that flows roughly what I need (750cc - 800cc), replicate drilling on next one and flow match them. Do it for all six or eight. I ordered 8 to have spares lying around.


I will keep you posted, should be fun. At worst I will have a set of 6 to sell if I ruin two at which point I will abandon this adventure

Personally, I wouldn't run water through fuel injectors.

My concern would be rust.

I would try to find an alternative.

What are you going to use to pulse the injectors?

My injectors finally shipped yesterday, they were on national backorder for last month... I guess they are new flavor of the month.

If I cannot properly modify these, I might just bump up FPR pressure to 5bar, which would make them adequate to fuel my set up... I might have to do something with pump set up, maybe do duals. Running at 6-7bar would be preferrable anyway. Race car . Superior fuel atomization this way.

Running these for couple of days unmodified just to see how they're doing. I set my FPR to 5bar. So far I have to run surprisingly high KRKTE (70% higher for Ford at 5 bar than 1000cc at 4 bar, I expected difference of about 35%) which doesn't relate to expected flow of injectors at all. They seem to be considerably less flowing that what they are reportedly rated at (630 - 650 cc/min @ 3 bar). I should be getting ~820CC at 5bar and I am not getting that at all.

I rigged simple flow tester with my old fuel rail, 6 injectors in it (5 x 1000cc and one 0280158298) and power to fuel pump and two injectors, 1000cc and Ford. I am leaving 4 remaining ones unpowered, just to plug the injector holes. I will give it 12V and fill two bottles and then measure what each injector flowed. We'll see if the stuff matches or if my FPR/pressure gauge is POS and shows boloney readouts on fuel pressure and why the expected flow at higher pressures doesn't make sense in relationship to KRKTE I had to use.

But the injectors are super smooth... I forgot how good they are after running 1000CC straight shooters Ev14. They were not that bad but stock Ford ones are improvement, no doubt.
