The time has come to announce the details of my transmission build. No one has attempted this before and there unfortunately are no off the shelf parts. Everything will have to be custom made for this application which means the build time will be around 10 weeks from this point. This thread will be updated periodically with pictures and details every step of the way. I will be providing complete documented details through the process.
Why is the transmission being built?
For one, to handle more power and for longevity. It is no secret I have abused my transmission from the moment I got the car. I have done more launches at the drag strip using launch control than... anyone really. These launches are abusive, generate tremendous heat, and shorten the lifespan. Once supercharged, the issue was exacerbated. At a single event in '09 I used launch control 19 times with a burnout each time which generates considerable heat. I have attended 5 such events. Additionally, I have done launches on the street. I would estimate a conservative 70-80 uses of launch control up to this point.
So the transmission is weak?
No, not at all. Actually, it took far more than anyone would have thought. At these drag events, I would also run back to back at times. Keep in mind, I bumped the launch control RPM up as high as it would go, 6200 RPM. These are 6200 RPM launches after a burnout again and again. I estimate 70-80 uses and a properly used manual clutch in ...byPublished on 03-30-2010 11:19 PM

Yet another spectacular review by Former_Boosted_IS:
Anyone that ever removed a single pipe on the intake track of this car has inevitably found oil literally dripping from the pipes. It is really an un-nerving thing to see oil literally caked all over the pipes that lead to your engine. I remember when I was changing my intercooler for the first time, I was very concerned this oil could damage my new investment. I guess there are a couple of questions that immediately came to my mind and the first was... why does this happen on the N54? Well it is obvious the N54 suffers from blow-by pretty bad. What is blow-by? I found a great explanation that I will quote:

Autocar is reporting there will be no M6 and I find that very hard to believe. Why not? Same drivetrain and motor as the M5, seems like a slam dunk to me. With M SUV's these days an M6 is suddenly out of line?

He're is a run you can add. G-powers stage 3 protoype. Stock internals with stage 3 boost. According to them it was a 6sp Manual and they will test the same setup with a DCT next week, thats all the details I have now. I will post more as I get it and edit this post.

No, this isn't a joke. Really. Automotive News reports that BMW CEO Norbert Reithofer shared this statistic during a call with analysts last week. It is unclear where this information came from within BMW, but it still comes as a staggering surprise that 80 (eighty!) percent of 1 Series owners believe that they are living with front-wheel drive.

Sticky (me) is Green, DSLJ5 (Drew) is blue:
These dynos were done in the same place. Conditions were very similar, favoring Drew slightly:
Both cars were on 91 octane + meth. Both cars are running the Gintani Stage 2 supercharger with meth. Both cars ran the same boost, 7.5 psi.
Now, this is posted to show that there is a significant difference created by the exhaust system and the same dyno certainly can provide much different results. I do not understand why people were critcizing Drew about his numbers or what they were even implying. Yes, Niterider (Brian) put down 505 on a DIFFERENT dyno, not this dyno, on a different day in different conditions.
Drew's run and my own are much more compareable as they are on the same dyno. People were saying, "why Did Drew only put down xxx blah blah blah" and going on some ridiculous witch hunt. The numbers are what they are, you can see the difference for yourself.
The headers and 3 inch exhaust themselves made a larger difference than we realized. Boost dropped 2 PSI due to the ...byPublished on 03-22-2010 04:29 PM
The Akrapovic Evolution Exhaust System for BMW M3 consists of flow optimized link pipes with 2 x 100 cpsi sports catalysts and integrated resonators as well as a completely newly developed and now split-end mufflers. This exhaust system, made fully from titanium, reduces the overall weight when compared to the stock system by about 23 kg. From approximately 2500 rpm on, the power increase is about 24 HP. The torque is nearly constant at 35 Nm over the stock. That is the real joy of driving: high speed engine benefits in daily practice due to the torque increase. It improves the agility in the lower rpm-range noticeably. Also, the engine is stronger in the higher rpm-range and the elasticity is improved considerably.
The improvement of acoustics played an important role in the development. The Akrapovič exhaust system amplifies and rectifies the beautiful sound of the 8-cylinder motor, without appearing invasive or having disadvantages in the daily use.
