    even with the say $500 cost of the diff (i dunno, could be higher? Shouldn't be.) it would be $1000+ savings..?

    Nah, just go to ebaymotors, search for low mileage New M5/M6 Pumpkin from a wreck (Should be around $599). If you're handy with a wrench, bingo just swap in in for a <$600 3.65 LSD upgrade.

    Congratulations to everyone who worked on this project! Impressive!

    @VargasTurboTech: What is your projected production capacity for Stage 2 turbos? The biggest turn-off for me to get RBs is the super long waiting list.
    From all the things I've lost,
    I miss my mind the most!

    What I meant was for you to make and release your own OTS maps for these kits. Just basic 91-93, and 100. Something that folks can use right away after buying and installing the kit. If they need more power, or a more fine tuned custom map, then they can use PTF to make to those maps on a dyno.

With Tony's parallel LPFP setup in the tank (OEM+Walbro) the LPFP Actual pressure is staying on target (and slightly above actually) without dropouts.
    Well just grab a 1M HPFP, and it's an easy swap, problem solved. Now for your 800+whp glory run, forget about the alcohols, ditch the 02 sensors and use C16.

    I am sure they will have base starting tunes, but At the stage 3 power levels on 93, 100, and e85, a custom tune is a must. Why spent 10k plus on mods and then skim on $250? Every car is unique, get the thing can can be the difference between long term reliable safe power and potential unsafe tuning right.

    What year is the car they are working on dummy? Do you notice how several part numbers have others above it that say ended? You just go in there and type in part numbers, and see they are all listed as the same, because that's the one currently being produced. Try searching by year, or taking a closer look before you try to rebuttal. And for Gods sake, please Don't ever quote me.

    LPFP pressure actually seems to go up to 80-90 under full load and that side really doesn't seem to be an issue "pressure" wise. Tony's setup is a parallel one and the only thing I could suggest at this point experimentally is to add in a wider fuel line to carry more fuel to the HPFP. Regulator may also be a great idea to look into and test.
    If low pressure is really going up to 80-90psi then he is overrunning the regulator with his pumps which should also be corrected. I'm not sure how the DME reacts to seeing higher than target low pressure like that. It might lower the pump PWM. Keep an eye on it. Ideally you'd want to bias the low pressure signal back to the dme to keep it observing around 72psi. If 90psi isn't enough try 100psi, etc. His parallel fuel pumps can probably support it. A higher low pressure should allow the high pressure pump to increase flow. Remember a wider line won't do anything. If you had a volume problem, low fuel pressure would drop. It's read at the high pressure pump inlet. But while he is rigging up a new regulator there are a few bits of 1/4" line in tank that should be replaced for 5/16" line.

    Dummy! It sais ENDED because it is recalled. Here is the SAME part number for a 2007 335i:

    http://realoem.com/bmw/showparts.do?...83&hg=13&fg=15

    ...and oh yeah, the part number was changed BEFORE the release of the 1M. So there is no way the 1M part number is different!

    I did search by year! Of course I searched by year. Who keeps part numbers in their head. Do yourself a favor. Find the HPFP for a 2007 335i and a 2011 335is, and for 2011 1M, by navigating via model years. Tell me what you arrive at.

    I have no dog in this fight, but you didn't say "just grab the latest version of the N54 pump", you said "just grab a 1M pump" clearly suggesting -- at least to me -- that the 1M had a different pump than other N54-motored models.

    Just my two cents.

    The 1M/335I/and post 2010 335I all share the same part numbers. But if you look at say a water pump, or HPFP from my car which was made in 2006, and compare it to the current ones, you will see big differences.

    Think before you write. Even if they were the same, you don't know the mileage of the 335I they are working on. Chances are it could be well over 50K. We don't all have low mileage occasional "autocross", crashed, and repaired vehicles. An HPFP at 8K miles, and one at 60K miles, are two different animals. And why do you think the HPFP was recalled? Don't you realize that the part was redesigned?

    Not only that, but no way in hell would i give up factory widebands and, technologically speaking, go back in time 15 years when there are much better alternatives than leaded fuels that don't kill O2 sensors

    Where have you been in the bast 3 years? BMW issued several different versions of the HPFP which was failing in earlier models. The latest HPFP version, coupled with software and injector recalls cures the major fiasco BMW had on their hands. This was resolved in 2010. All new N54 motors that come out of the factory will have the latest part numbers. This is how recalls work, whether its for an airbag or fuel pump.

    Your posts suggest that there is a difference in output and performance in the 1M fuel pump, when in fact there is none. ALL fuel pumps are the same. If your car does not have the latest pump, it is because you did not receive a recall letter from your BMW dealer to get it replaced.

    I am fully aware of that. What I am trying to say is (and Neil thinks the same way) that your posts suggests that the 1M pump has a higher output or is somehow beefer, stronger, makes more power than the other pumps which is simply not true.

    EXACTLY my thoughts. Turkeybaster somehow thinks he can easily ditch the O2 sensors and run open loop all the time. Idiotic idea at best.

    No, you won't. You might find a 335i that hasn't had a HPFP recall yet, but BMW has gone through quite a few model #s on the HPFP part. This is why you're seeing different part numbers. There is no other HPFP out there right now for this platform. End of discussion.

    We can hope that the new M3/M4 cars have one compatible with the N54, because it will undoubtedly be beefed up. Or unless someone figures out how to rig up two HPFPs running en-tandem.

    BINGO! I am also hopeful that other components from the M3/M4 will be swappable as well: LPFP and injectors.

    Guy, the recalls weren't sent out in the mail. BMW doesn't do things like that. I got my HPFP changed, with the SAME OLD part number mind you, only after I failed emissions testing at well over 50K miles. If you haven't failed an emissions test, and just go to a dealership, even with problem codes, they typically won't just sit there and start applying recalls to your car. At 100K+ I'm still on original turbos. These suckers have a waste gate rattle recall on them, up to 80K miles. Even with waste gate rattle the dealership refused to do the change.

    It truly is best for you to quite quoting me. I don't want to have anything to do with you.

    Yes they were. I got one in the mail and so have many others! As a matter of fact I get regular communication in the mail from BMWNA related to my car. You did not get yours because you did not call BMWNA and did not have them update the mailing address associated with the VIN of your car. This also means that you won't get future recall letters.

    By LAW all car makers are required to send letters to all owners if there is a recall on a critical component of the vehicle that can jeopardize passenger safety.

    Get your ducks in a row mate.
    From all the things I've lost,
    I miss my mind the most!

    Yes, so which part number does he have? What are the differences in part numbers? was the equipment redesigned? Even if nothing has changed, how old is the OP's fuel pump? An LPFP, or HPFP, at say 50-80K miles is VERY different from a brand new one.
