    • 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.

        Another week gone and the car has not even fired yet, good god.....
        I think it might just happen man. Good for him if it does you know. Then we can start seeing what his car actually does and even if it is on low boost.

        Nothing wrong with being optimistic I suppose, I am more of a realist however.

        Well it's running so realitistically you might want to wait until friday is over on the west coast before making blanket comments. And im sorry will suffice.

        No, how stupid are you? You cant even answer a simple request for the current status of you car. Has it started, simple yes or no answer. Even a stupid person can answer that. I can care less about what these guys say but some how i get the notion that even you feel there is truth to what they are saying and you are trying to figure a way out without making yourself or Gintani look worse than it already is. I know your going to deny it but maybe if you were a little more of a man about it you wouldnt have to come on here and ask people not to tarnish your and your builder's reputation.

        You are probably correct on your hunch, I get the same feeling. That being said you should probably expect to be hit with Stick's rep stick today, how dare you question the dicator or speak ill of Gintani.

        I can not wait to run him with BOTH of my cars at Shift Sector, he will be knocked back down to earth very very quickly.

        Sounds like you must be close. Is Friday over yet on the west coast as we are all waiting for an update.

        note no personal attacks

        What in the holy hell do your cars have to do with my car or project? Why do you keep making it about you? For the last time, this project has ZERO to do with you.
