    • 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.

        I don't really see why winning or losing to you is what matters with my car. Really, I don't get it.

        Because at one point you said your car was going to be faster than the Weistec CLK's and now you are going to eat those words and pay $1000

        ....it's Tuesday and the car is Still not running. A week ago they posted a pic of a completed motor on a stand ready to install and the car is Still not running, now Sticky is using Meth install as the excuse for the delay.

        No, I never said my car was going to be faster than Weistec CLK's and Weistec cars have never been my goal. You seem to have made everything about yourself for some reason.

        I don't even care about $1000 that's completely fine no big deal... I don't even see why you keep bringing it up as if it is.

        I'm not making any excuses I haven't even called to check. Why don't you find out and let me know?

        The point I was making is there is *a bit* more involved than just dropping a motor in and starting it. Relax.

        When you go pick up the car, please let me know bro. I really wanna see it. I'm in depression that I have a broken car. So seeing your car finally alive will give me hope for mine. LOL

        A bit more involved? Been there and done that and continue to push the edge.

        For the record you originally did say that you would be more than a match for the clk's and now the tune has changed to you talking about Jim's C car. Why the Change?

        There is no change. I was told I had no chance with either. I have consistently said I would race either. The change now is that apparently the monetary offer to race the C dropped Click here to enlarge That isn't on me.

        I'm very aware what you are getting done and what they are capable of.

Remember, my car has been at Weistec all winterClick here to enlarge.....just sayin

        I will give you 10 to 1 odds but your minimum wager has to be at least $1000.....say the word.

        I will give you 2 to 1 with the C BS.......man up and accept a bet

        Why not? I already stated that was only fair due to the wait. It will make for a great vid comparison plus I haven't been to Chicago. I want to try out the local restaurants and the local Polish women.



        10:1 $1k is fine with me.



        Um ok?

        Well, JRCART never committed to 5:1 on the C, but said he would determine the bet once he got dyno numbers. I guess after he got dyno numbers, he offered to 2:1, which it looks like you accepted.

        Maybe JRCART forgot about the 2:1 offer on the C. Click here to enlarge
