    Completely wrong, yes sure if the turbo is at max flow if you have a boost leak big enough to affect the flow going into the motor sure you will drop power, the guy stated clearly they were easing into it, meaning the turbo was not even closed to being maxed out, losing that o-ring is a very small boost leak, I guess you also ignored the part where I actually ran without one for a good 6 months, during this time the car put down almost 650WHP on stock frames, so I am not just guessing, I inadvertently ran without the oring and while it was a small boost leak, when it was replaced, the numbers on the car didn't change. You lose a boost hose, of course you can't make power, you leave a small boost reference hose off, you will have a direct boost leak, but unless you are completely maxing the system and the turbo can't make up for it, you will not lose power. I mean what do I know we only build turbos for a living. Your calculations are great on paper, we deal in the real world.

    Hey guys, Pure Turbo dropped off their M4 for a little JB4 dyno tuning. The car has a JB4, full exhaust, factory intake system, racing fuel, meth kit running dual CM7 nozzles (overkill with the race gas... but better safe than sorry first time out), and of course the hybrid turbos. It's an MT. There were a few little bugs to work through but the end result exceeded my expectations. I'm pretty impressed with these turbos. Spool is delayed maybe 300-500rpm, similar to RB N54s vs. stock N54s. But damn does it hold more power to redline. There is probably another 30-40whp in them but since it's not our car I didn't want to push it "too" hard. :lol

    That is actually a brilliant idea. I bet it would likely fix the issues we're all seeing.

    This is true if turbine efficiency is being maximized(Boost leak is greater than combusted mass volume) in this case it likely wasn't based on the statement that this was initial tuning and vanos tables for spool any leak losses would result in better pid control later. As for the meth leak hurting octane, it likely wouldn't be noticed until pushing timing. My concern and the reason I also would've stopped is the fire potential not the loss of power from the leak. Engineering calculations are great until you put them to practice as I'm sure both of you know.

    Like the title says, looking to run Stock Turbo FBO/Tune 135's or 335's in the Washington DC Area. I have an Intake/Tune 5.0. Can post video results.

    Funny thing is, this is an option the shop which installed my twin disc was exploring - just threading a delrin nipple so we can adjust the throw of the slave cylinder to compensate.

    I also called SPEC. Spoke to Danny who also told me to take down the trans to take pics. Problem is, I had a shop put it in due to lack of time and all the talk of failed installs due to not lining up both discs on the input shaft. I don't want to pay for labor to pull the tranny, take pics then pull the trans again once a fix has been identified, or wait for shipping back to / from SPEC. It is a daily driver for me. Plus the other issue is the shop I had it installed at is closed as of Friday for holidays and won't be back open til January 5th. So its either I wait (which I don't want to do) or take it to yet another shop. It looks like either way I'm paying for double labor, it would be nice to know the second time around will fix my problem and not just a "we'll see" type thing.

    Invalid ^ From an engineering standpoint I can understand where he is coming from when he states that a leak in the system can cause power loss. Its the same concept in fluid power systems. Leak in system> System works hard to make up for lost pressure> system not running at optimal efficiency. Its good to see the owner of a company act this way. Mainly the reason i didnt put the money down on the stage 3 twin turbo kit.

    FINALLY ARRIVED!!!! Christmas came early this year!!! Motiv-900 HTA3794R Packaging is AWESOME!!! I mean you know this is a Premium kit when EVERYTHING comes individually sealed and secured so that nothing RUBS and is Damaged during shipping. The list is Personal to you! This is a really nice touch, you know everything was meticulously checked specifically to your kit. VERY NICE! This Exhaust Manifold is so pretty I wish it was exposed so Everyone could see it.

    Whoa whoa captain sensy pants, easy there. First of all I can comment on any thread if I decide I want to, as this is a public forum, secondly I was stating a very simple fact, that your small boost leak at the charge pipe is not going to cost you any horsepower at all, the turbo is just working harder to get that lost air through the motor. I said nothing about power numbers, blah, blah, blah. I simply pointed out a fact. That you posted that up there without provocation is a little insight into your insecurity about what you set up may or may not be putting down. But hey, if you think that o-ring is costing you 50WHP, by all means that is your right to believe something that isn't true. Can a big enough boost leak cost you power, sure can, will that o-ring cost you any, sure wont. I mean I only ran my charge pipe for 90% of the shop car testing without the o-ring in as I hadn't realized it was gone, I finally discovered it recently. You enjoy your day now man. Drink a beer or something and relax, high blood pressure is a killer.

    Tony, after watching you and Rob Beck bicker back and forth like two 13 year old private school girls over on n54tech, I'd rather you not comment on anything I post but thanks for once again speculating on data you haven't seen. No one said anything about challenging your "world record dyno queens" by adding an o-ring, just that the data correlated to the leak. Time lost trying to recover from and compensate for a book leak is time that could be better spent making power, not to mention the loss of octane. Guys like you are what make guys like me not want to post any real data about anything on here or anywhere for that matter. You never have anything value-added to contribute to any conversation I've ever seen you in, only making yourself look foolish and immature. Actually, those are my personal pics Sticky posted in the OP that I originally posted on n54tech. If I had wanted them over here I'd have done it myself. There might be a reason for that...hmmmm, wonder what it could be. Not sure if you try to be a douche rocket or if it just comes natural but either way, well done. You have warranted yourself quite the reputation. Thanks for validating. I'm done with this forum.

    N54 HPFP are under an extended 10 year/120K miles factory warranty from BMW. Take all your mods off. Fill up with 93, not E85. Dealer can deny it if they find mods/tuner/high ethanol content(no more than 10%).

    Talked to spec. If we are all having the same issues we should bring it to their attention. The asked me to take off the tranny and send photos of the splines to the output shaft. They would like to see how everything sits. They confirmed that the tob should be in the low setting. But they did say they are installing one on a 135i in the beginning of the year. i just think if they are aware of the issues from us they should take quicker action to resolving the issue.

    Besides a slightly low pedal, and me going against my judgement and torquing to their initial specs, this clutch is the ONLY clutch I would own for this car, pedal feel compared to the 3+ is night and day, the twin is so much nicer to drive, you can slip it, it holds more power then the 3+, etc, etc. There is really no drawbacks, I had zero problems installing it, the tranny slide right up to the engine like its supposed to etc. Of course it seems a lot of people had different experiences with this clutch, but I can say it was a breeze, and its awesome to drive.

    How do you increase sales and profits if you are BMW? Take a Mini, change the styling a bit, and give it some BMW badges. That is what you have here in the upcoming X1. BMW really did not need to do much of anything as Mini products are already using the BMW B48 four-cylinder motor which the X1 will also use. This really is essentially a Mini with a BMW badge. Expect front wheel drive versions and an all wheel drive option as well. Also expect it to be similar to the 2-Series Active Tourer (itself a reskinned Mini) offering similar powertrain options but with different styling. BMW has the X2 spot in the lineup open and with an X4 and X6 in production the speculation can begin on whether BMW intends to produce a 'coupe' variant of the X1. Considering how hard BMW is pushing X variants it will likely come. Exciting times at BMW for driving enthusiasts these days.
