    • 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.

        Just curious who is holding up the build at this time? Tranny shop or Gintani?

        Why not put in a stock tranny, lower the boost if it can't handle it, and drive the car until they figure out the transmission issues?

        Do they have to have your car 100% of the time to fix the 'special' tranny in it to further progression and figure out what is going wrong?

        It sounds like the tranny company can't deliver the product they said they could in a timely manner...that being said i don't think you will beat jrcar in a HP battle or 1/4 or 1/2 mile race. I hope I am wrong. Maybe on a track but 99% of the population does not race on one...

        THERE IS NO HOLDUP.

        THERE ARE NO TRANSMISSION ISSUES.

        Go build it faster if you know better.

        absolutely no hold up, the original plan was 39 months, they are going to beat that by at least a month

        So they only have to put it together with no software/tuning? How long has it been this way?

        I have been semi-against jrcart this whole thread until you just said that.



        edit: If instagram is more important and gets more updates than this thread something is wrong...

        It isn't that instagram is more important it's probably that it's easier to just post a cell phone photo update don't you think? Hence the whole point of the app.

        I don't care who you are for or against. You have no clue what you are talking about. So just sit back and relax, okie dokie?

        Ya I'm a total retard for building my own car. You seriously have no idea what you are talking about give it a rest already. You aren't accomplishing anything other than wasting time.

        Ya having the most powerful E9X is a joke I guess.

        900 on pump should be funny for all involved.

        Class act.

        Due their Instagram update says 900hp, we all know when tuners say hp they are talking crank and if it is wheel they designate whp or rwhp! 900 hp might be able to take the C, it will be close, but you are worlds apart from the CLK and you know it!

        What is funny is you posting on here like you were going to have something for the Weistec CLK's for the past couple months, try 1200-1300 hp bro. IMO 900 is a joke after a 38 month build. I can not wait to collect on the 10 to 1 bet...remeber the minimum wager on your part is $1000.

        It says 900+ I'm sure you can figure out pulleys and fuel change things. Is it ok if we break it in at 900 for you? Is that good enough for you?

        The C won't be a challenge. But since you offered to race it for money I just hope you honor your word.
