    • DCT Build Part XII - Build complete, pictures of final assembly, transmission cooler, and Viton seals

      Well, this has been a rather lengthy road to completion but the transmission is basically complete. The car was dropped off by SSP last month to Gintani who should have the motor in by the end of this week. The problem is SSP mounted their trans cooler in the location the heat exchanger for the supercharger needs to go so SSP will need to come to Gintani's facility to re-run their lines as the cooler will need to go in a different location. What took so long for this update? Well, we have been waiting, and waiting, and waiting for SSP to send us details on the Viton seals that required 3 redesigns but never received the information on why these seals are superior to the stock units.

      So, I decided to do my own research and here is what I came up with. These are the stock BMW seals used in the DCT. What is wrong with them exactly? We do not know other than they apparently are not up to the task:










      Here are the Viton seals which delayed the project by 3 months. Viton is a synthetic rubber used for seals, O-rings, things of that sort. Viton was likely used as it is less susceptible to decay and already used in BMW applications such as in VANOS. Viton has much higher temperature and chemical resistance characteristics than the stock seals. Here is what they look like:










      This is the DCT cooler that was mounted by SSP up front. This needs to be moved somewhere else as the supercharger heat exchanger will need to go there. This means SSP will need to come out and run their lines again checking all their fluids and so forth before tuning can take place:














      This is the final assembly. So, the transmission is built but it took about a year longer than estimated. I believe I was as patient as possible and hopefully this will all be wrapped up in December with a built motor, built transmission, a YSI, and a ton of horsepower.

        If the car isn't ready by Feb I may just pull the plug. I'm sick and tired of missing events. I'm sick and tired of having to defend the shop. I'm sick and tired of not enjoying the car. Nobody is paying me for my patience while my car sits there losing value.

        I've had about enough... but hopefully January is the end.

        I don't blame you, I would tell the shop, it's Feb or bust, and not pay full price for a unfinished product if they fail....enough is enough

        I mean it's possible but that's not cheap.
        Wait? Tow the car?
        Why not just drive it there? Saves you $2400,- minus fuel...
        If it is finished you can drive it around, right?
        Or is it just a purpose build trackcar?

        I feel you man, I honestly do. There is only so much time you can wait. It's been a long time!

        I think you've been plenty patient with this build, at least with the shop and the constantly extending time line. I think 99% of us on this forum would have been done a long time ago so kudos for sticking with it. I have no monetary investment in this build but I would hate to see you have to just stump it and start all over without ever having received a finish product. A lot of time and money went into this thing I really want to see it finished. So git er done.

        Then come to Vegas and give me a test drive Click here to enlarge

        I thought you had the car back based on a prior post or that you were breaking it in? Perhaps I misread something, but whatever. In any case I would move on and be done, you can buy and mod something else that would like be as fast or faster in far less time. I assume you would stay German so no GTR's and American cars are cheap and inferior as you have stated.

        So since money is not an issue for you I would consider the following

        Audi/Stasis R8 (Extreme Challenge model with the supercharged V10) its German, blown and very different. Or a UGR version turnkey and go. Just write the check
        SLS with the Weitec blower setup would be cool as well.

        Otherwise all the usual suspects apply. M6, M5, 997 Turbo, S4, RS4, SL63 or 65, Cl63-65, C63, M3 etc... The new Carrera S is a ball to drive.

        Its unfortunate to hear of your troubles...

        Because I'm not going to put that many miles on my car plus I need tires, supplies, tools, etc.

        They were breaking it in.

        You really just don't get it. I built a BMW to build up BimmerBoost. If I launch domesticboost.com any time soon I'll buy a domestic to promote it with. I'm just going to do whatever is best for the sites.

        Right now I just want this car done. Anything beyond that will come when the time is right. If the car is the way it should be, I won't be looking for anything else for quite a while.

        I was trying to offer a kind word...

        Being 1 of 1 or 1 of few is novel but at this point it doesnt seem worth it based on your own stated frustration. Jumping to a new platform seems the logical idea and perhaps costs effective as well. Since you're pushing German rides via your site and you wont buy a GTR, Vette, V, Mustang, Camaro etc... I offered some unique options. Its not hard to understand why you attempted or intended to build the car. The real question is it worth the cost in time, money, stress and so on. I'd call Stasis get me the R8 V10 with the blower, throw some insane Carbon Fiber wheels and ride that $#@!. Promote the sites and have something fast with a warranty thats not on every block. I suspect should you finish this out you will bore of it quickly and want to move on. The new M3 is soon upon us along with a host of other great rides.

        Or eat some crow, buy a C6Z and start Domestic or American Boost and do something new. You could even call these guys for a more plush interior

        It's all worth it if the car does what it should. It's the time that I can't get as much value for.

        Come on, I'm well aware of what is out there and what can be tuned and to what degree.

        Eat what crow? The M3 with the YSI and built motor is going to be very, very fast. I already bought domesticboost.com it's all in the plans. When the time comes I'll move on to a new car.

        Don't mean to get of topic though. While your car is at Gintani. Build up Domestic boost, you don't need to buy a domestic car for that. There are tons of people already doing some badass builds with domestics right here in our boostnetwork, your boost network. @Sledgehammer @ultimateendz and I are already have reputation and build status to promote domesticboost. Whenever you're ready, you know you have $#@! to front page all the damn time. Click here to enlarge

        Setting up the domestics is going to be a little complicated.

        A few reasons.

        First, there are a lot of models. And I will likely need to break it down like this: ford.domesticboost.com gm.domesticboost.com chrysler.domesticboost.com

        Then the engines, models, for each. I mean it's not the end of the world or anything but it just doesn't come as naturally as the German stuff.
