    Please read the Q & A, your first question is answered there, of course we offer a 1 year warranty for failed hardware, ie housing, etc, we do not offer any warranty for failed pumps, We all know these pumps are not the best design, BMW has been sued, and issued a recall over them, they are better now but they are still prone to failure, this upgrade is designed to take their failed experiment and allow it to flow enough fuel to run the WHP levels we are coming up on without adding fuel from outsides sources, we found the pumps holding up very well during our testing, we blew up a bunch of them, but everyone was blown up by us doing something to it we shouldn't have, once we got everything playing nicely we never lost another one. #3 We do not touch the pumps, the system uses stock pumps, we do suggest removing the filter in the inlet of the pump as it is very restrictive, but we wanted this upgrade to use stock pumps, and it does, you will need to either send in your rail, or we can provide a modified one and charge you a core until we receive yours back.

    So what I have won't save me any money for the double barrel kit. We'll will the single barrel be good enough for stage 3 twins? In for this product anyway.

    Why does the single barrel dip at 3.5K RPM? Is that when it starts to activate?

    They both dip there, if you look at logs no idea why, the DME has full control at that RPM, its most likely because it sees the HPFP over REQ and then yanks it back, overshoots and then finally gets it smoothed out (honestly we do not know, but that seems plausible), that dip is there in every log. Also I am not sure you read fully through the thread, the single barrel is just a single pump running at all times like the stock pump, there is no activation point.

    let me know when you get them in stock, ill drive up so you can test fit both versions on my n55 and we can see what works best...as the hybrid turbo is only the 1st step for this car going top mount soon after we get the fueling problem handled

    what's the downside to having it ALWAYS activated? the stock control just doesn't know what to do with it/too much flow or something?

    With the 'double barrel' system, should it provide actually double the flow

    also cool to know you worked out that you COULD overdrive it after you tried for long enough haha, even if it had to be a very precise level of overdrive Click here to enlarge



    hopefully not haha


    .. time to find the limits of the stock INJECTORS now.. how exciting is that? (not sarcastic, that's amazing the platform is able to do that in a few months!!)

    *adds to list* because i just NEEDED to have another couple of grand to spend haha
    I missed these questions sorry about that

    #1 it is extremely reliable
    #2 engagement is basically undetectable, if you look at the logs you really cannot see where it comes in, this is with a small amount of fuel being added
    #3 You cannot have it always activated for multiple reasons I wont get into, but lets just say the DME doesn't like it and start shutting things off

    #4 I never said it could not be overdriven, I said trying to overdrive it in the stock location was a very bad idea and most likely impossible idea due to the location, chain drive etc.

    #5 The Injectors are not going to be an issue ever on this engine if the flow numbers are correct, too high an RPM level might be as the injection window will get to small, the motor is really the next limitation. Thanks for the questions!

    That's the hardest thing about DI engines, the timing for injection window gets tiny for the amount of fuel needed in the higher rpms too. It's pretty crazy how it works and I honestly commend you Tony for getting into this game with basic knowledge on the n54 and now you're a Guru with how it all works, from turbo to fueling.

    Not a big fan of group buys, its very easy people to say they want something and put their name on a list, when it comes time to buy it there are many excuses as to why they can't. People can knock us taking pre-order deposits, but we only take them for one purpose, if you have something tied to your decision to buy, you almost always follow through.

    I am 100% on pre-order deposits. I wouldn't make something that costs 1k+ for someone unless I knew I have half of their money first for materials. It's for both parties and like insurance.

    @VagasTurboTech Tony I read that your test car had a walbro 450 in tank as well as inline. I thought this would draw to much power and result in blown fuses. Will your stage 3 turbo customers or big ST folks require this type of lpfp upgrading as well?

    We have not had a single blown fuse or even the phantom fuel pump warning consistently since we installed the dual 450's running on the stock wiring, all we did was put in a 25amp fuse over the stock 20 amp and it has been working flawlessly for us for thousands of miles. We will be switching over to a 450 parallel set up in the near future though, it would pull similar amps and should flow more fuel

    1 Awesome

    2 Awesome again, and with the next

    3 right fair enough - 'because reasons'/'because DME' is good enough lol i can think of a few, probably wrong but it makes sense lol.

    so (i'm sure you'll answer this later or whatever so no need to now) you'd set the activation RPM to just a bit before the stock pump gets overwhelmed, a few hundred RPM or something.. also to keep it alive longer i guess?

    4 ok fair enough again haha, much easier to change pulley/belt length on your current setup.

    5 yeah that's true. I'm talking about at high RPM's injection window though yes, When i worked it out i could well have been wrong and or the numbers could be 'conservative' (75% or whatever) - am just thinking E85+7krpm or higher + 700whp+ could show the limits. Steady state/mid RPM, like you say, if the numbers are correct, no worries haha. I hope i'm wrong!

    thanks very much for the replies! Great answers Click here to enlarge

    what about the wiring itself? for sustained high load on dual 450 pumps i mean

    probably something better sorted out with experimentation, i guess.
