    DCT Swap

    I am putting the financial aspect of this out of the picture for just a second and am PURELY curious about simply the technical workings behind this. Once we see the limits of the steptronic I think that this would be an interesting option if we could get it working, mainly in the TCU department. I haven't done any research, but what exactly are the 1/4 times on the DCT vs the other two? Does the transmission bolt up with existing, manufactured parts(scavenged from the is?) I've seen some interesting launch control videos... Whats the news Click here to enlarge

    EDIT: Maybe it would just be easier to trade the car in.

    you would essentially be swapping the entire car into another chassis. ECU, transmission, controls etc... everything.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    I remember reading DCT being tested to be 0.5 seconds quicker in 1/4m. I would have picked one but they began the production 2008. Haven't bothered trading in my oct 2006.

    So I guess a 335is is the only way to get a dct and n54 at the same time?

    Yes, unless in Europe.

    Maybe I'll wait a few years and get a 335is Vert... They have the e93 option for the is? Also, I wonder if they still include the forged internals in the is?

    Don't see any reason why the is would have different internals.

    Don't know if they have the E93 option but I'm sure someone will chime in.

    I would think so but even then it is just best to swap the cars.

    I wouldn't rely on that info. The launch always seems to be sketchy in the "clutchless" type transmissions. Maybe on something AWD (like the GTR) where the formula consists of simply dumping the clutch at high RPM's, but I don't think the DCT is intuitive enough to maximize the launch on a RWD vehicle.

    Oh, yes you can, which is why I still hold the 60 foot record for the E92 M3...

    MT's and I have to find the slip or post I made but it was 1.7X.

    I think I can get it into the 1.6's which the manuals will struggle to get near.

    That's pretty impressive and better than I thought. I can't see a half second advantage through the 1/4 mile, though. Don't get me wrong though, DCT would be my first choice.
