    Power goals aside, I don't understand, why so many people want tons of boost/power/torque down low? As mentioned, 85-90% of people don't have enough tire to handle that power.

    It's all preference really. Some guys enjoy the torque down low. I personally like the 6466 and actually moving up to the 6870 when the built head is installed. I don't mind the lag from 3500-4000 because that pull to reline is unlike anything you feel with smaller turbos. On windy roads however I do feel the larger turbo holding me back a bit.

    Makes sense if some are old vs new there might be some issue but at this point, they are all new, just a month old for all. Hmm, thats interesting... I initially had the pins out but they are in now and still getting them.

    Not saying that your 6466 is excessively laggy, just that all things being equal (gen 2), a 6062 would be even more responsive at low RPM than the bigger turbo. The fact that a turbo is capable of 900+whp is of little consequence to someone targeting 600. Either turbo can make far more power than what is being requested, but the smaller turbo will make the power band wider and be more responsive. You are saying that anyone that wants faster spool, more boost at lower RPM, is greedy because your turbo gives more than anyone should want or need. In a perfect world, we could have a single that feels like twins below and still has the flow to push hard to redline. Using your logic, why not get a 6870? It gives even more top end potential with capacity of over 1,200whp. You are right about one thing ... I really want to get the performance of good Hybrid Twins, with the simplicity and accessibility of a top mount single, and think that the 6062 is as close as I can get without staying with low mount twins.

    Actually its capable of 900whp+, just not on this platform yet. My point is you're not really accepting more lag. More power down low is just going to be more of a traction problem while sacrificing potential up top. Driving my car, I don't see how even more response is going to help you. Just stick with hybrid twins if that's the case. I'm guessing you've never driven a twinscroll 6466 car. It's not laggy, at all. I never asked who wants to make power at 2500rpms. I said who wants MORE power. I had to dial my throttle map BACK because the low-end with the OEM throttle mapping was too much. As it is, I can barely keep my tires from spinning at 3500rpm and I'm on 315s. Most of these builds aren't running enough tire to make more power down low useful. There's quite a few cases of blown motors these days, it's true. But you can make >700whp without needing to push more than 600ftlbs (far less actually). The guys making 600-650ftlbs are in the 800whp range anyway. In the end, its whatever people want to buy. But this isn't a 2JZ or a 4G63. The N54 can spool some turbo. :)

    Hi, I remember you were using NGK 4786 non-resistor plugs gapped at .025 a while back - do you have any updates on them? I have a set sitting in my garage after I swapped them out for stock, and wanted to see how you feel about those plugs now, as I didn't see it on the spark plug list on the first post of the thread. Thanks

    as long as its a gen 2 turbo, i think youll be happy. that being said, id recommend a 6062 for your application.

    I'm getting a 3100 code for boost pressure deactivation. I don't have the stock solenoids anymore and just wiring off wastegate pressure now. What can I do to get rid of the code? Thanks

    Velocity26 replied to a thread Single Turbo Question in N54
    Sered, Your 6466 is supposedly capable of ~850hp at the top, while a 6062 is estimated at ~750hp. For someone targeting ~600hp max, why should they accept more lag and a higher rpm power band with nothing in return? Either turbo can easily meet their power targets, but one of them has the benefit of more response for those who daily drive these cars. Asking who wants power at 2,500 rpm? The guy who is driving with an auto transmission in D mode while on his daily commute. If this were a dedicated race car, your comments would make a lot of sense ... minimal downside with plenty of upside potential. Another factor for all of the guys chasing 700+hp on their N54, the blown engine thread shows a lot of broken pistons and bent rods that were caused by people pushing 600+tq numbers. To those that plan to build the bottom end, good for you ... but you account for a very small percentage of N54 owners.

    I inject mine with apple juice the night before and leave it in the plastic shrink wrap to prevent it from leaking out. About an hour before cooking i pat it dry with paper towels, rub it down with oil and liberally apply a generic BBQ rub that i make. Smoke @ 225 until internal temp hits 205. Immediately wrap it in tin foil and towels and let it sit for an hour or two. I also smoke it fat cap down and flip it fat cup up while its wrapped - this seems to really let the fats and juices redistribute throughout the meat. I really enjoy cherry wood for the smoke but pork is extremely universal.

    Thats odd. I always have the opossite experience of tony. He loved his twin disc with the hard ceramic puck discs and i hated mine. I havent had a problem with my gtr plugs and gc turbos. 26 psi without an issue. Ill find out more when i go back on the dyno. It however should be mentioned that i am spraying a lot of fuel through port injection while he is full di. So id keep that in mind.

    Just an update for people. Do not bother with the GTR plugs. For whatever reason, they do not like the combustion chamber environment of a DI engine. They are obviously fine on very high power GTR's. But I tried them twice to make sure it was not something else. I had 5992's in there, car ran perfect no misfires, gapped the GTR plugs, put them ran it again on the dyno. I would get the small dips on the graph, and could hear the plug misfires. I pulled them back out, check gap again, put them back in, same thing. I put my 5992's back in, ran it again, clean pulls. So in my opinion these are a no go, this was at a very reasonable 650WHP, not a crazy number or very high boost. The only plugs I will run in these cars currently is the 5992's. Hope this helps someone save some money.

    I dunno why there's an obsession with spool on the smaller turbos. I've got logs of my 6466 hitting 20psi at 3000rpms in 4th and positive boost at <2k; it is not laggy at all. Making anymore power down lower would be a waste imo. I don't think you're going to get any better response out of it either.

    NGK 93026 (DILKAR8A8) Just so you are aware I'm ordering these plugs currently and the price has gone up to $20. You have it listed for 17 on the first page just giving you a heads up. I want to have an extra set with me just in case my current ones blowout on the dyno LOL

    Our Australian friends at Nizpro were nice enough to answer some questions for the BimmerBoost N54 community which is hungry for automatic transmission upgrade options. Nizpro recently demonstrated their upgraded ZF 6HP21 capability with hard launches on the drag strip. That is obviously just the beginning and development continues. BimmerBoost wanted to know when they were planning to release their transmission upgrade, what the upgrades entails, if the TCU software can be purchased separately, etc. These questions and answers below should provided some much needed details. BB: What is the expected cost? Nizpro: A fully internal Nizpro transmission upgrade will be approximately $ 7900 Australian dollars. BB: How close is it to release? Nizpro: We would like to be able offer full upgrades by Christmas . BB: Who is doing the TCU software tuning? Nizpro: Software calibrations are being done in house at Nizpro. BB: Does the $7900 AUD include software? Nizpro: Yes the calibration will be included as a complete package, however various calibration will be needed for various power levels. BB: Is it possible to purchase the software separately from the hardware? Nizpro: Absolutely, our plan is to offer calibrations totally separately. There will be a number of different calibration we will make available, for customers seeking different requirements. All will be based on standard transmissions, or of course our own upgraded transmission, if you have an upgraded transmission from another workshop you can certain use an off the shelf calibration but how it will behave I have no control over. BB: What is the expected torque capacity? Nizpro: Actual maximum torque numbers are a little hard to say, simply because there are many parameter that come into it. There is also a direct relationship with maximum torque numbers vs durability. In other words we could claim the transmission is capable of 1000 ft lbs of torque and in the fine print disclose it will last for half a mile at the torque figure. Customers need to be aware that the standard HP21 is rated at 450 nm, however this has a durability of 60,000 miles. It is clear that the stock transmission will cope with double its factory rating although its life expectancy is more like 20,000 miles those torque numbers. BB: How soon will Nizpro be testing the software as thus far the 335i with Nizpro upgrades did not utilize the software in its 1/4 mile runs? Nizpro: We actually have. We have track tested the car twice. Once using our upgraded transmission with Alpina for a base test data. 4 runs were recorded. We are not concerned with overall quarter mile times simply gear shift times for comparison, between calibrations. The second lot of testing using software changes were done the following weekend at a different track. The track had little grip on the day so the results were not really useful in terms of quarter times. This is all good news. Nizpro is on schedule to release their product this year and they will not force you to bundle their hardware and software together. Here are some additional details which should help get a better idea of what is involved. Things are looking up for the N54 automatic scene.
