    Any idea of the pressure increase by a piggy. I think i've seen like 1/2 volt over stock, but I'm not sure. Is it about 500psi per volt?

    Not sure how the voltage maps over to psi...i've read in the N54 docs that the highest HPFP pressure is 2900psi (200mbar) and that's what I've also seen in cobb logs when I asked Rob once to max out the fuel pressure for me just to see how it'd affect AFR/fueling and how the car would behave...the car just adapted it out and closed injector duty cycle to meet AFR targets naturally...you may/may not be right on the fuel limitation, the analogy does make sense to a point...

    Almighty Shiv has claimed many times that around 480whp is about the power level where the stock fuel system will be starting to see its limitations...i gather that's what he's seen while tuning that ASR 135i, his own 335i with ASR turbos and a few other RB cars including mine...on mine he pulled off 496whp though (uncorrected) at ~18.5-19psi@6k rpm, well at least on the runs where it didn't miserably misfire

    Since I'm unbanned there with a threat for a permaban if I fight shiv, I'll post all my cool data here. If anyone wants hard data and discussion, they can come here for it.

    It's possible the high pressure pump moves less volume at higher pressures as electric pumps do but I don't believe that is the case. Dzenno should just hit up the dyno with a 21psi map and monitor his high and low fuel pressure so we know the answer. Click here to enlarge

    honestly i still try for the "noobs who happened to buy a procede"s sake. Any of those guys still going all crazy fanboy over there (yet accusing all us JB4 users of doing the same) deserve shiv....the results speak for themselves....

    still not...hold on.......... nope......still not seeing any much in the way of procedes in the top lists. About 2 that aren't shiv in the first 2-3 pages on drag times. Oh wait, it costs more, it must be better.

    hope that was legal bashing....if its true its good to go right? Click here to enlarge

    All you guys want is more data so you can knit pick every detail, why? Cause thats all you guys do.... bicker about the details.
    How does your car run? If it runs great then who cares about some dumb air fuel graph

    Agreed! He conveniently avoids my questions as well. Sad part about all this is that there are a lot of new comers to the N54 game as those cars are becoming cheaper and cheaper to buy second hand.

    Those bans are a total joke! ...not only because they are done for stupid reasons, but mostly because they can be EASILY circumvented with a little knowledge. Yeah, they can ban a specific username, but they have absolutely no way of stopping anyone to reappear on the forum.

    This is the same guy that jumps on everyone who doesn't bow to everything Vishnu posts and who thinks he's got far more tuning knowledge than everyone else including the 'NOOBS' who run COBB. lmao. If I were Shiv I'd shut that guy up lol. Can't be good for business...

    Don't expect that from Shiv Click here to enlarge look at his new beeyatch SIKH335! Can you report that guy over on e90 for being obscene and jumping into hotrod's thread and being obscene...i got banned for just arguing a technical discussion, that guy is just dumb/retarded/obscene..he should at least be warned

    SIKH clearly has small dick syndrome. He can't possibly fathom hotrods car is so fast lol, although I'm skeptical as well. Does 200 lbs of weight reduction on a 335i that's not even FBO equate to 123-125 mph traps? I seriously wish I could run side by side with him just to see.

    Hotrod plays games, I don't like it. He makes love to a Vbox.

    Although I am skeptical of his results as well, considering his car is apparently some sort of super factory freak that can trap 2-4 mph faster than the fastest stock turbo N54s, I can't say I dislike him. He posts results, graphs, logs, and I can't dispute that.

    I wish he would post some more technical data, how he shifts, what he did to drop weight on his car, techniques, etc. All we see are just that, results, graphs, logs.

    Hotrod stated that 99% of the time he lets the car shift on its own from a thread he posted..

    Hmm, found this interesting video that shows the vbox in action on hotrods car. Now we all know, the 335i speedo reads about 3-4% too fast on stock wheel/tire size (e.g. actual speed is around 76-77 mph when the speedo shows 80). This was GPS verified on two of my N54s with a 9500ix radar detector.

    Even if he ran drag radials, it wouldn't account for the speedo reading almost 5 mph too slow, considering they all read fast to begin with. The speedo was right around the 110 mark when the vbox chirped at the set point of 116 mph, per the video and it reported 115.x? Considering the damn speedo is fast to begin with, THEN couple in the fact the speedo is 5-6 mph slow over the vbox trap speed?
