    Ok All
    I'm posting this here as opposed to the Jeep or LX side because I hope our Turbo'd SRT4 betheren can help answer some fueling questions and give some insight to fueling issues with the Mopar line.
    With the new changes that are happening in blower tuning for the V8's on my end I have to look for bigger replacement injectors that are sort of plug and play (forget tuning for now) just R&R.
    This is what I have for Mopar Injectors 3 inches long so far.

    P/N 05037479AA 6.1 Hemi Stock engine
    Flow 30 Lbs/Hr @58 PSI

    P/N 04891574AB 392 Mopar Crate (Originally a Neon Injector)
    Flows 52.3 Lbs/Hr @ 58 PSI


    P/N P4510529 2.4 L 16V High Output Turbo Neon
    Flow 62.5 Lbs/Hr@58 PSI

    Anyone else can offer any other injector spec's???
    And now fuel pump changes my thoughts right now are dual in tank Holleys 12-922's
    And fuel rail tech to come.

    Have you given thought to these? They're site states that these custom injectors are ideal for 426's and most supercharged packages..

    Thanks that is a good alternative.
    I see the website states a 42 Lb/Hr injector so thats a good fit over the stock injector.

    Now I would like to find a bigger injector than a 62.5 Lb/Hr injector.

    Thanks Again\

    Yes HHP has done a great job in creating injectors for the powerhouses, but IMO are very much overpriced.

    Jeff,

    SRT4 injectors have been used in several 6.1 applications.

    I believe the 03 0r 04 model SRT4's to be exact???

    Also, i would recommend allowing me to change up the title to this thread to gain more SRT4 views and support??

    You say the word, and I will fix the title.

    ok so stock 03 srt4 injectors are 49.80lbs/min@58lbs
    stock 04-05 injectors are 55.23lbs/min@58lbs
    Stage2/3 srt4 injectors are 64.76lbs/min@58lbs

    Deatchwerks sells bigger plug and play injectors for the srt4 but they rate theirs at 43.5psi of fuel pressure.

    the deatchwerks 590cc injector is equivalent to the 64.76lb/min mopar injector
    the sell a 650cc(61.9lbs/min@43psi) and a 750cc(71.4lbs.min@43psi) one of those should be more than big enough for you


    are you going to be using some sort of rrfpr? if you're not going to be tuning in the near future i would at least get one and set the fuel pressure lower so that the bigger injectors dont kill your gas mileage, and a rrfpr is always a good idea when in boost.

    For right now, in a low boost test it will be a returnless system.

    When we start making some big boost I'll have to go return system with a rising rate regulator.

    Did you really want this posted in the SRT8 forum? Say the word and we'll move it to the SRT4 section for you.

    Doesn't matter to me, this was originally posted so that us V-8 folks could have a post to search for options for the Hemi.

    if you go to the crappy forum there are tons of stock injectors for sale for really cheap. if you're concerned about them just send them out to deatchworks for a cleaning/inspection. it will end up being cheaper that way.
