    Magnuson supercharger injectors flow data?

    (This question was originally tacked onto another old thread but now I started a new thread with a more accurate title for the information I'm looking for)

    I'm working on a 2011 Escalade with a magnuson SC.

    It has pink injectors with the part number 0 280 156 030
    0280156030 (listed both ways to help with future searches)

    I found this number on the Bosch spreadsheet here http://www.hptuners.com/forum/showth...ch+spreadsheet

    I still dont have the data I need, but by comparing with the info on Greg Banish's DVD I found that the Flow Rate listed by Bosch at 400 Kpa and at 300 Kpa equals Gregs flow data for the 39lb injector x 0.956.

    So what i'm going to do is use all of Greg's data and multiply it by 0.956

    Does anybody have any better ideas or better data?

    That injector I believe is 527cc and 50lbs @ 4bar. It's a SRT4 injector Stage 0.

    Also, it seems strange that the flow data from the Bosch spreadsheet shows a lower flow rate than the stock injector values I pulled out of the vehicle.

    Is my flow data wrong, or did Magnuson not do their homework and supplied smaller injector than the truck came with from the factory?


    Stock (I believe) tune pulled out of the vehicle attached.

    This is the info I'm getting from the spreadsheet in the link, Row #1008 from the spreadsheet


    Injector type OE NR. Type
    0280156030 0 280 156 031 EV 6


    Operating pressure (kPa) Q-stat (at operating pressure) (g/min)
    400 356


    Q-stat with 300 kPa (g/min) Q-stat with 300 kPa (ml/min)
    308.3 440

    EDIT: Corrected earlier mistake:
    I'm dividing 356 g/min by 60 to come up with 5.933g/sec @ 400 Kpa, Which I convert to 47.09 lb/hr @ 58 psi. This DOESN'T match what magnuson told me. They descrived the injectors as "41 lbs/hr."

    Your stock injectors are 50lbs @ 4bar also. This is because this Escalde is a flexfuel truck and ethanol needs higher volumes and therefore bigger injectors. Take them to measure to be sure.

    Color me shocked that an aftermarket company would have no clue about the actual characteristics of some random injector they threw in a kit. /sarcasm

    If you can confirm that it's actually an SRT injector, then you could open a Dodge file (using brand X or Y software) and look at their injector data to actually see mass flow vs on time in the Chrysler cal data.

    Lol.

    OP, just try to grab a set of LS9 injectors and call it a day. Then you can easily get all the cal data.

    If my memory serves me correctly, they are indeed SRT4 injectors.

    If you're trying to go by the "canned" tune they send for the inj. data, don't. They are horribly hacked up scaled tunes. They're not even scaled well. They're terrible.

    I did not do the install on this setup or get to pick the injectors. The LS9 injectors are shorter than the ones that fit on this setup.

    I plugged in all the data from the Ford 39 lb injectors scaled just like in my orginal post. Started it up and the fuel trims and wideband readings were almost dead-on from idle all the way up to high rpm WOT. I don't know if that makes me clever or just lucky, but I'll take it.

    I read this thread when trying to figure out what these pink 0280156030 injectors flow. Looks like they should flow 47.09 at 58 psi but the Magnuson tune calls them out at 43.98. Since that is wrong how screwed up are the rest of the injector tables????

    I have the original flex fuel injectors from the 2012 6.2L truck I am installing the blower on that flow 49.8 and all the factory data for them. They are about .6" shorter than the pink injectors but I can take out the .5" rail spacers and they fit pretty good. I am thinking of using these instead of what Magnuson sent. Does anyone see any problem in doing so?? Will the fact that they are now pointing straight instead of at an angle make any difference??

    I probably wouldn't have ordered this kit with injectors if I knew this is what I was getting. I thought I was getting ZR1 injectors which are just a little bigger than what I had. The Edlebrock kit I was going to get reused the stock injectors if it was flex fuel from the factory btw. Almost wish I would have went that way.

    So does anyone see a problem just running the stock 49.8 lb at 58 psi injectors in the maggi manifold???? Didn't really think the change in the angle they install would be a problem but just wanted to verify I'm not doing something wrong. Stock they are layed over about 10 degrees and in the maggi manifold they are straight.

    Seems the data for the stock injectors would be a lot more accurate plus they are a little bigger.

    So we know the flow rate. What about the offset tables and such that need to be modified as well for these injectors?

    This thread just kinda got left hanging. What did everyone do for injectors for the Maggie tvs1900 setup? Use the pink injectors that comes with the kit or is it possible to fit the original flex fuel injectors back in without any problems?

  19. #19
    My TVS1900 came with GM 2012-2014 6.0 Truck injectors, which flow 50lb/hr at 58psi, are black, made by delphi, and carry GM part number: 12613412. I will gladly provide that data.

    Others use LS9 injectors, and I believe the newer TVS1900's have the LS9 injector from the get go.

    Cant help with the pink injector data but I am sure it exists somewhere. Good luck!
