Did my first RB turbo dyno after install.
mods are JB4, RB turbo, FBO+Meth and e50

[rdeterman]

very solid. AT or MT?

[AWTT335i]

Nice numbers. What's with the drop in power and lean spot @3.5k rpm?

How much boost and timing are you running? Do you have a datalog to show us?

What is NFZ?

My guess is: A lot, and a lot.

bump for boost and timing!

I believe this is the RPM band in which you approach the vanos...

[Markyd83]

Curious to see the mph you run. Nice numbers.

Alpina Trans flash done I presume as well?

[ChuckD05]

prob 20-21 midrange down to 18 with 12-13 degrees

level 10 isnt really a "transmission upgrade" so to say... You can search yourself and see with your own eyes. I was about to start running into this problem so to get around snapping the axles or blowing up the tranny, I only do 50mph rolls in third gear and up... I never go from a dig because I know Im just asking to break something and honestly ireally dont want to be blowing half shafts up every time I go off the line lol...really not trying to blow things up and having to go thru that. So I just do only third gear roll ons just to be on the safe side. You def need to get a LSD for sure. Your car will drive soooo much different and feel more planted to the ground.

Just make sure you do enough research on level 10 because that would be a big wasteof money, especially if it doesnt really "upgrade" anything and keep the tranny from slipping due to power...at your power levels if you drive it like I was saying, just doing 3rd gear rolls, your tranny will be fine

This.

Enrita’s build has held up and that’s fantastic, but everyone else who has put an “upgraded” build in their car has had it fail, and fail rather quickly. You could put the strongest tranny on planet earth in an N54, without better access to the MCM and TCU it is irrelevant. Shims and whatnot to up the line pressure are great but are ultimately defeated by factory transmission logic, it will simply work around the hardware upgrade and the end result will be identical.

There is no proven hardware upgrade for our ZF box. We need to figure out the software, the stock hardware is fairly capable if we had serious access on the software side.

And yea, I haven’t launched my car from a dig in at least a calendar year.

i won't be at this power levels for long. i am going to detune around 15psi for everyday driving. but definitely will keep an eye if something goes bad goto fix

Yes i think Alpina flash is a must with this setup.

LSD is something thats been in my mind for a long time... i may just pull the trigger on it, i dont know. i only had the car with RB for like 2 weeks

[Killerfish2012]

There's a lot of denial about getting a trans upgrade on this forum. Allegations of wide spread level 10 failures, when I haven't seen a single one. The belief that "an alpina trans flash" makes any kind of difference when you are running +240whp more than stock is eye opening. All I can say is that the G37 guys have been running level 10 in their twin turbo setups, all day. And that's with 10 second time slips to show for it, with not one reported problem. It's just a no brainer.

This is just really backward. You need a strong enough hardware first, before software upgrades. The only software issue has to do with being able to upshift from 4th to 5th in WOT. This will requrie a thorugh re-programming that I don't think we'll ever see, because the buisness is just not there to support the $ it would take to get done.

Then why have multiple 517 and LVL10 builds failed, and failed very quickly? We are completely unable to write to or amend the MCM and TCU as matters currently stand, save for flashing files (alpina etc) that are already there. We have no control on the software side. The 4th gear timing flatline is a separate issue, in my opinion.

The hardware is there, the builds that 517 did were pretty damn strong in terms of actual hardware. But the software logic remains the same, and compensates against whatever hardware you may happen to have by reducing line pressure. Shims and that crap won’t do it.

It could also just be that the hardware “upgrades” suck. Either way, their record of success is pathetic. Enrita is the only person who has posted long-term regarding his trans holding up. Lostmarine, Sikh, etc all had theirs explode on them.

There is a big difference between Enrita, and those other two guys. Enrita is an HPDE/roll event only dude. Lostmarine and Sikh, go from a dig at the strip. With the amount of torque a low 11sec/ 10sec N54 produces, there is absolutely no torque converter that can hold up long term to that kind of abuse.

Enrita routinely does full mile roll events that run through all gears. I’d argue a 3-4-5-6 pull puts as much heat/stress on a trans as full bore launches from a dig. Halfshafts can be addressed via hardware, I wouldn’t argue against that.

I guess my point is this: There is absolutely demand in this community for a serious 6AT fix. There is nothing special about the 6hp box in our cars. There is no doubt in my mind lvl10 is mechanically capable of building a strong enough transmission to handle ST boost curves and whatnot.

So demand and willingness to pay is there, and from a hardware standpoint, the parts are there. Then why is there no real product that is being adopted by the dozens of people who would happily pony up for a good solution? The answer in my mind is because we have no ability to control the software. That’s just my intuition; I know we don’t see eye to eye on this.
