if your description is to be believed, you drive an e90, don't you? i.e. don't have an f30 or the ZF8? if that's inaccurate please update it so we know what everyone's background is car-wise. if you did, the LCI models 2015+, like you said, do have the 8HP50 rated for abut 375lb-fts. and the 340i makes an underrated 340lb-ft from the factory. breath on the b58 from a different angle and now it makes 400lb-ft. see the problem I'm getting at here? the upper limit of torque for the transmissions is almost where they come from the factory anyway! same is true, to a lesser extent but true nonetheless, for the 328/330. regarding examples, I looked briefly, and to be honest didn't find any examples of a transmission failure in an F30 with the auto. but either way, the transmission is rated to a certain amount of torque for a reason, and even if people say it's "bulletproof" I'm not comfortable pushing too far past that manufacturer recommended limit. that's just me and my opinion though. other people may decide to trust the transmission go to 400wtq and be totally fine. also, I hear people talk about these 500hp n20s running around rampant in like Brazil or something, but have never seen a dyno on here or youtube or anywhere else. if these mysterious things do exist, I'd be shocked if they were on the the stock transmission, and if they are, they probably won't be for too much longer. I'm happy to concede that I'm wrong if you prove it to me. i.e. if you show me cars running well over the tq limit of the trans for a good amount of time, I'll gladly concede that it's more durable than I thought.

I mean, I've only heard of a 380WHP N20 in Brazil based on a dyno on Pure Turbos N20 Page: https://www.pureturbos.com/store/bmw...-n20-stg2.html

As for the the amount it can take, the numbers are spot on for what it's rated. I, too, have heard of many people running it well past its "limit" with no issues... yet. ZF makes some beefy trans and they are likely underrated just like BMWs engines. That isn't to say it was severely underrated, like saying it would be fine and reliable at 550nm. From my understanding, you can push the ZF pretty damn hard and past its limit and unless that thing is old as the oak tree in your backyard, it's not going to fail immediately. The real question isn't how much it can take, as people have pushed 700 on it (Thread I think on the F30 site, somewhere. Just look for max torque and ZF) and it didn't bust, but how LONG can it take this beating? No doubt pushing it like that is going to decrease the longevity quite a bit.

I personally won't get to test that much, as I'm capping at 350wtq (thanks N26). But I think it's important to note that they can take above their rating, but no one knows for how long. You'll likely see that torque converter fail first. In the end, if you are so worried about your car breaking, then don't push it past the rated torque limit or just not very far past it. I'm all for finding how we can make the most power and more importantly the safest power, but this is something we may not ever know.

exactly. you can push the trans running 4xx-ft for one dyno run, that doesn't mean it can handle it. like I said before, the transmission is rated at 330lb-ft for a reason. I'm sure you could probably be fine at slightly above the rating for a long time, but once you go too far past the rating, it's probably going to lose a lot of longevity.

There was someone DDing like 600wtq on that tranny. Curious how long it lasted or if it's still alive lol.

Can't remember, but did you decide you're done trying to beat your best time for this platform?

Maybe... The only other quick time was this guy in brazil who was running nitrous and literally blew of the car. I haven't heard from him in years but he ran a 12.9. As for the stock platform... I'm done! I am pretty sure the b48's will make it there.
I'm interested in running a pure turbo. That's a death sentence for this car but really doesn't matter. I'm not sure if Jay Thomas is in here but I want to see how his car is doing. He still getting the final touches on his custom tune from somewhere in Germany and he is running pure turbos (stock internals). I don't see many videos or actual numbers from anyone running a bigger/better turbo. So, looks like its up to me.
Also, waiting for MHD to drop and reevaluating what my options are then. I will be getting a newer transmission and diff. Switching to coilovers and getting a pair of DRs. For now... taking a break from running the car as much as I used to.

I don't know about big turbos being a death sentence, so long as you keep it to a reasonable amount of boost.

[f30nick]

I wonder what time I'd put down with a 6 speed since I've only seen the auto guys giving their times :thinking:

You should. I think key thing with us is to stay at 24 and below.. The bigger turbo alone will help with the top end, which is where the stock turbo falls on its face. I have the MHI Big Turbo and just waiting on HCP to get this custom tune rolling.. Put her at 350/350 with the upgraded rod bolts and see what she can do on a proper track.

We also have two guys approaching the end of their building of the engine, so really want to see what they'll put down on the built ones.

Hmm. I have a spare nitrous kit. 🤔🤔

Damn 12.8 that’s impressive, you my friend might be the fastest in history, lol

[lukeiswright]

This is a video I found of a 328i and a G35 driving on a closed course in Mexico! He's FBO tune and so is the 328i.

Sometimes wish these vids would be like few mins longer, 1 pull doesn’t do it justice

lol I'm sure I could find a few more videos of that same race somewhere, let me look

What I meant by secret was never using launch control to launch with, the quickest way is manual mode no launch control. 30 minutes ago I recorded a .95 g launch that way. The difference between launching that way compared to launch control is night and day. As to the wheel spin, yes there are times when road conditions are not perfect and when I launch that way the system transfers to the front wheels enough to only spin them for a sec. No I'm not lying about the times. In ideal conditions as in, 60 deg temp, sea level, 1/4 tank of gas, no junk or cargo, no passenger, 93 oct, no ac, I'm probably missing a few but that and the fact that I have the jb2 up to 4over for boost, air scoop, afe filter, non runflats on lighter wheels, drilled slotted rotors, ceramic pads, sports trans option coded, lowered, strut bars, 38k miles (about when the n26 engine is operating at its peak power of its life cycle, new plugs, and with the one g launch I am consistently doing the 1/4 in 13.2 13.3. And yes it does make sense just compare to a 335 with literally the same hp with LESS torque and lighter, I think the 335 xdrive runs a 13.2 or .3 also

Post a time slip... or it didn't happen

Forreal though. Please post one of your slips.

Current record for this platform is 12.83 on the qtr mile.
