Figured this is a good place to ask since pretty much the only people running 1600 cc/min injectors are us single folks...

Does anyone have a GOOD list of Bosch fuel injector part numbers with colors (the tops of Bosch are color coded) listing flow rates/other stats?

Regards,
B

 

what do you need to know?

 

I need to know what colored tops correspond with what flow rate. I have seen several "1600 cc/min" Bosch injectors that people sell and they aren't all the same color.... That leaves me scratching my head!

The most common ones I've seen are light blue or greenish blue on the top. The ones I have are brown. I'm just curious to know part numbers and flow rates for sure

i am getting 8 in the mail soon, i will let you know what color they are.
bosch part number is 0 280 150 846 , though.

 

I've seen light aqua, medium blue, and white tops...
They were all supposedly 1600's.
The different colors are for different applications.

I think its pretty much like Ted said.
The aqua ones are 0 280 150 839 and come from CNG fuelled Ford V8s.
The brown ones are 0 280 150 837 and come from CNG fuelled Chrysler V8s.
Then there are some blue ones (and maybe white ones going by Teds post) which I'm not sure about.
From what I know they are rated at 160lb/min which is something like 1680cc/min.

 

Does anyone know if there are any 1600's with a high impedance (resistanse) coil ? , I dont really like the inline resistor way .

 

I haven't seen anything over 900cc/min that came original from the factory that was high impedence.

You do know low-impedence fuel injectors are for better performance, right?


-Ted

 

Yes , but all my other injectors are high and I dont want to mix them.

 

If anybody has a part number for the 1200cc's I would be eternally greatful. I contacted bosch australia and spoke to someone in the motorsports division. He gave me a part number but said you have to get them through Ford Motorsports USA.
this is what he said "Our Product manager advises that the CNG injector is not suitable for petrol.
The only 1200cc injector is 0 280 150 835 it is called Indy Blue and is only
available from the Ford USA Motorsport division.
This injector is manufactured by Bosch USA for Indy cars"

But then he sends me another email that says "The injectors are top feed. The 0 280 150 835 should read 0 280 150 839 Indy
Blue. We are unable to assist any further as we do not sell them In Australia
Made for Indy cars and supplied by Ford Motorsport in USA only" So I'm thinking to myself...which is it? 835 or 839?

Well I called Ford motorsports and they have there part numbers start with "M" not 0. The guy here also says the 2 largest injectors they have is a 150/lb injector and a 40 something lb injector, none of which would be a 1200cc injector.

i've been searching for this injector for a few months now and its getting frustrating!

 

Oh and in reference to your original question...here ya go! http://www.bosch.com.au/sat/motorspo...linjectors.pdf


Now if someone can help me find the top feed low impendance 1200's I'm looking for!. And its not the 842 injector....the 842 is for CNG operation only which I beleive is methanol only.

Also does someone know how to convert gallons per minute to cc/minute?

Don't forget that you can order 160lb injectors also from Accel, they are Black with a White top(or maybe Light Grey top, depending on how you look at it) in color, you can order them from Summit, Jegs or from nearly anywhere that carries Accel, the part# for the 160lb(1680cc) injector is #74160. On a side note, me as well as other people I know have checked the resistance in the 1600 injectors and have found that they are really not low resistance, they usually measure 5.5ohms when cold, and 7ohms when hot, this is another reason why you can actually use 1600's with a PFC and don't need resistors, this ONLY applies to the 1600s though, all the other low impedience top feed injectors in the same Bosch type body that have been tested with lower flow rates are really low impedience. Here is another thread supporting this:
https://www.rx7club.com/showthread.p...hreadid=255008

 

i have heard of a couple pfc's popping because there was no resistor, it might be right on the edge

 

I measured my brown-topped "1600" injectors, and they were around 3 ohm. I put 10 ohm resistors on them.

Brian

 

its oms law, the less resistance you have the more current will flow....

the pfc i wanna say had a 1 amp injector driver

 

That's VERY strange cause me and everyone that I know has measured them, even the brown ones that you're reffering to, and they all came at the same resistance level stated, I would make sure that you have 1600's. Not argueing, just make sure.

 

Well that is strange. You know when I got them, I noticed that they had a number like "148" or something on the side. I thought that maybe this was the flow in lbs/min which would be about 1550 cc/min. Being a little uneducated about the subject, I just shrugged and figured that "1600" injectors were really more like 1550 (much like many people say a car has a "2 liter" engine when really it might be 1.94 or something). I installed them and they work just fine up to dyno-tested low-400 rwhp. I bought them from K2RD if that is of interest to anyone.

I checked my records and my brown topped injectors each measured 2.5 ohm. Maybe I don't have 1600s after all... perhaps they are something a little different?

Brian

 

Sounds like you definately don't have 1600's, also to clarify something the 1600's are actually 160lb injectors which in reality flow 1680cc's.

 

The other blues one that i know about are 0 280 150 842 There also 160lbs injectors that are exactly like the 839's

The white ones i believe are 0 280 150 846 These are also 160lb injectors but there response time is slower then the 839/842/837.

what injector are you referring too wargasm?
Look for the bosch part number on it. Not the color
Then i could help you.

 

Who know's about the injector referred to as the "indy blue"? I have talked to rep's at bosch and motec(motec carries them) and the rep at motec said they flow about 1400cc depending on fuel pressure.

Weird though I have never heard of 1400's but that size is perfect for my application. 350-380rwhp on a 60-1.

 

I'm building a fuel injector tester (like RCEng has but not as fancy) and I'm going to test and clean my own injectors ... We'll see how many cc/min I get outta them heheheheh

 

The injectors are in the car now so I can't see the part numbers. Besides, I think I remember someone used a grinder to obscure the part number. Dicks....

 

Those indy blue are the 839's.
Although the 842's are also blue and have the same characteristics.

 

Thanks for confirming that Enzo. If i'm running a 87 turbo 2 which do I want for my secondaries then? 839's or 842's if you say they have the same characteristics. There must be some difference or they would not have different part numbers correct?

Can you confirm flow rating's of them and are they a direct drop in into the secondary rail or are mod's needed?

Thanks Enzo

Edit: The 842 is not for petrol use, its a methanol injector, so I'm assuming i want to with the 839?

BTW the 839 isn't even listed on the link to bosch's motorsport injectors. Does this injector even exist? lol
