    • 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.

        Let's do both. I mean so you know the C63 BS can't win in a straight line who cares? Comparison for fun for data and for people to see.

        Nobody gets it. It's interesting, really, from an enthusiast standpoint. I don't care about the time. I don't $#@!ing care.

You're suggesting someone pain themselves with the same mistakes with zero knowledge of this process, yet having to make the same upgrades or better upgrades. If the builds were began at the same time and upgraded to the same degree, then this could be a possible comparison.
        You have others trying to match. They can't, and haven't, and aren't running. It's not just me.

Please do not insult my intelligence by trying to convince me any $#@!ing build should take 38 months to complete...I suppose this would be Alex from Gintani?
        Who cares what you have paid to get built? Different platforms.

        Look man, let the ego go.

        Weistec supercharger the first M156, not you. Glad you got to them but if they didn't have people pushing it would be hard. I'm the guy pushing Gintani's DCT. Not fast enough for you? Sorry, f'ing sorry. Oh no, oh darn.

        Alex could be faster. Alex could respond better. Alex is how Alex is but that doesn't mean a car can't get done. Bro, my E92 was way bananas on stock internals. Your C63 would have trouble, ok? Seriously, big trouble. You know that as you don't even want to race it any longer. Your CLK will have trouble too now. No, it simply will. Not because there is anything wrong with it, but you aren't even analyzing this from a technical standpoint.

        Seriously, no bid deal. I'll come out to Chicago. It doesn't matter. Whatever, have fun, chill out, relax.

        LMAO, C BS can't win in a straight line??? I am confident bot cars can spank you but the C BS is not a drag car, it was built as a road race car. You can run the CLK if you want to run me, my weapon against your weapon, what's wrong you affraid of 900-1000whp Sticky? Yep, while Gintani is playing tiddlywinks with your car Wiestec is perfecting and fine tuning the M156 platform builds.

        All this pussy footing around the issue tells me Alex/Gintani and Sticky already know the car will not be running this week.

        Top 5 Excuses Used By Sticky and Gintani Throughout The 38 Month Build

        5) The DCT took much much longer than anticipated (ya think?)

        4)The block is flexing (do you realize this is like Exxon setting up an oil drilling rig and striking water instead of oil because they didn't bother to investigate and do research before they set up the drill?)....$#@!ing GENIUS!

        3) This is a first of it's kind build, it has never been done before, this build makes the $#@! NASA does look likes childs play, this build is on par with building a time travel machine

        2) My vagina is really sore

        1) It must be that time of the month, my cramps are killing me

        You? You who? Me...? My hands are clean in this.
        I think you have been reading between the lines with all your intelligence too much. Seriously, go read a book, it will do you good.

        Lame response to a lame question. THE OWNER OF THE CAR DOES NOT CARE ABOUT TIME, I find it ridiculous that anybody else would care, let alone tell him how to build his car and what to do about the build. Sounds to me like a fat kid that dropped his ice cream cone.

        This is the funniest thing I have read so far. How did I get involded? I though you knew everything. I'll tell you what, I'm just a regular guy, and I'm telling you that I am not impressed with what you have done, or have paid to have done, or what you could have done. I DON'T CARE and I'm sure nobody else does. Your attitude in this thread has been ''look at me, I can do it better'' and you are mad because nobody is looking. How old are you?
