    • 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.

        Why don't we just do a side bet on if it's ready or not for Shift-S3ctor?

        Hi 5
        Long time is relative. I just enjoy modifying BMW's and pushing platforms. There's people who do here.

        Better yet lets make a side bet on whether or not you can run it at Shift Sector without break-in excuses. Open up the barn door and let the scape goats out to graze.

        I can hear the excuses already.

        I don't understand I have been saying all along let's run. All I'm saying is run the cars when they are ready to run. Why would I risk a motor that you keep reminding how long has taken to satisfy your ego? That doesn't mean anything to me.

        Why would you even show up at the event if you can not run balls to the walls with it?

        That's like $#@!ing a chick but only being allowed to put the head in....complete waste of ones time.

        Um because it's just built? Seriously, what kind of question is this?

        Pretty sure it was 2 to 1 and thats at a drags strip in the 1/4 mile, all bets were for a drag strip 1/4 mile...and after you run the CLK

        You flapped your jaws about the CLKs being more closely matched to your car, don't make me go digging for quotes.

        Why are you all of a sudden being a pussy about the CLK race?.

        Why are you all of a sudden being a pussy about honoring 5:1 on the C63 and saying neither of your cars would lose?

        I'm simply breaking my car in. Sorry my timetable doesn't fit you but once again I'm not going to be running high boost as I'm going to be testing the car out as well. How about I see how everything holds up then I push it ok?

        That girl in the pink is simply hot as hell and the girl in the red in that one pic is 5'0 and maybe 85 pounds with tits. There is a reason I got comped so much stuff. When we walked in... it was like we ran the hotel. I suppose my badass suit and expensive room helped.

        Well if and when Gintani is ever finally able to make combustion in all 8 cylinders in your car and you take your sweet ass time breaking it in like a little girl breaks in her tricycle and you can drag yourself and your car to Chicago maybe I will give you a race against the C but only after you run the CLK. My C is a road race car and I would not have a problem dialing in the suspension and putting on some DRs whilenit isn out in Californian but the idea of $#@!ing around with it once its home does not really appeal to me. You see I am fortunate enoug to have two BS's one for drag racing and one for road racing and I did it thst way so I would not have to worry about constantly switching set ups back and forth. Now you can call me stupid all you want but you are the stupid one if you can not realize my logic here. I am however very very excited about doing that 20 to 1 road race we discussed. shall we do that in two weeks at Willow? Order up those coil-overs tomorow, I do not want any excuses...we all know you have become the king of excuses as of late.

        I know you are probably upset that it will have taken over three years for Gintani to build you a car thst is a notch or two lower than the CLK, I would be upset too.
