    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.

    I am pretty excited about this. Newb335guy contacted me when we released the kit and there was a little bit of back and forth but we finally decided on the kit with a 6266. Got the kit all coated satin titanium with a cool DEI titanium heat shield. Just had to lay all the main parts out and show everyone. This setup is just going to rock, no doubt about that.

    Looking back at my track logs, I am generally exiting a corner and feeding in power between 3200 3800rpm and WOT by 4000rpm. On occasion I could be WOT @ ~3200rpm (absolute earliest). How small a single is needed to get excellent response from this rpm? If I had to modulate a significant spool up between 3000-4000rpm then it would be a PITA to handle. Obviously looking at dyno charts is not really a fair indication of performance in this application. But I guess a lot of people are going WOT from ~60mph in around this rpm and might be able to comment on how instant the response is? Total power goal not really as relevant to me as having power on tap from this point on.

    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

    Potentially an interesting drag race here as it pits three very fast cars each representing their nation against each other but Autocar screws the whole thing up. The Nissan GTR and the Porsche 911 Turbo S are not all that different from each other. Both feature twin turbo six-cylinder powerplants, both have all wheel drive, and both have dual clutch transmissions. The GTR is heavier however with less torque on paper. No direct fuel injection for the VR38DETT motor and of course a front engine layout. It's also quite a bit cheaper than the Porsche. The best horsepower per dollar value of the trio is the Hellcat but you already knew that. Just as you likely knew it is the heaviest car of the trio. We're talking 400 kg more than the 911 Turbo S or in other words more than 800 pounds. As this is Autocar they have no clue how to launch the Hellcat. The car is still spinning its tires when they go green. Why? What's the point of the drag race if the Hellcat never even gets a chance to hook up? Of course they also provide no data because it's Autocar and we should all just be happy they aren't doing this in the rain while sipping tea. They try again and the Hellcat again does its stupid spin until the tires go green routine. At no point do they think of going from a roll because producing quality performance comparisons escapes the people at Autocar. Essentially we get a frustrating and pointless drag race video. Someone tell these idiots at Autocar THIS is how you drag race a Hellcat.

    I have a VM Top Mount PTE Gen 6870 and I canyon a bit. I'm around those RPMS as well and my car is okay. I can imagine a smaller turbo like the 6062 or the 6266 shining in something like this with low to mid boost around 550-600whp. It would be near instant spool and power delivery at that rpm for either of those turbos.

    Haven't heard much of anything. Dinan's hardcore street offering is... well, even calling anything they offer for BMW street cars hardcore is generous.

    Jason AuBeast will be running a Gen2 6062 with a VM kit he and I will be sharing info closely. Yes it was contemplated long and hard 6062 6266 and 6466 in the end I settled on the Gen2 6266.

    My Stealths went back to Rob for evaluation the Stealths were an upgrade from Rob from my original 15T setup. In return for sending the Stealths back in I received a new 15T setup that I sold and used to start my single adventure. I totally enjoyed my time working with Rob, and running his turbos. Rob and I accomplished what we set out to do, run in the 10s and set a record doing it :D

    I feel like the new Gen2 6062 would have been a good fit too. Work on that 2-step at 6000rpm and some slicks and I'm sure you'll get off the line. Looking forward to your results! Congrats on purchasing such a badass setup. What are you doing with your RBs?
