    Delphi 830cc High imp injectors - GT35

    Has anyone used the Delphi injectors on a BT build?
    I was looking at the 830cc injectors for my stroker GT35 build.
    Are they up for job, not going to run the turbo to the max. Thinking 20psi for a daily drive
    The block and head are ready for assembly, waiting for gasket sets, arp and misc stuff. So I need to start thinking about fueling.

    never used them myself

    They will be fine with that amount of boost but when you up it make sure you have a 4 bar or a Adjustable FPR just in case you need more fuel

    What fuel pump are you going to run?

    044 or similar will be needed for that level of supply

    Thanks Andrew, I have 4 bar FPR to install. Got an IE fuel rail so need to plumb the FPR into the rail.

    Yip got a 044 pump that will be install in a swirl pot. That should be enough hey.

    I think Bill@Badger5 uses 830's in his Race car so he will know more about them than me

    I guess if Bill uses 830's in his race car, I'm pretty safe

    I do indeed run 830's, but along side 750's so please dont use me as a guide for injector sizing.. I run 8 injectors 750+830 per cylinder

    830's should be adequate for 20psi GT35 boost flow.. (IF) you do keep it there.

    22psi on my gt35 hybrid is make me 460bhp, 12psi makes me 360bhp

    The 830's when I first used them max'd out at just over 500bhp when I 1st used them, so had to get more fuel in.. I used to run 35psi boost to 9krpm back then. Currently quote conservative at 26psi peak boost and 8800rpm hardcut

    Bill, you are one crazy dude, 35psi
    I think you should just run 4 x 044 pumps direct to the intake

    I dont plan on going over 450bhp for awhile, so think 830cc are safe for now.
    Is the delphi a good brand? I hope so, as I have paid $200 for them.

    Strange I did'nt see you there when I was making them, aligning it and machining them into counterbores, and welding..

    easy for some folks...

    not so easy for others, to do it right.

    your engine running ok now?
    whens it going to do its 35psi 600+bhp target then?

    seems like forever in the coming.. You must be patient as heck? All that time and effort, £, and not there yet (that would be frustrating for me)

    We need a 600bhp S3 on the forum

    I hope so but i'm just going by what it last did but then it had standard cams, 3 bar FPR, 0.63 hot side, and oil passing the rings into the cylinders and not fully mapped, just not getting my hopes up.

    Now have Piper cams, 0.82 hot side, Adjustable FPR 1-5 bar, and new JE rings so yes i hope it gets near to 600 or 600

    If it doesn't hit 600 i will drive it and enjoy it with 500+ then look into the best way
