    • 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'm honestly not all that concerned with you or anyone in particular I'm concerned with my car.

        1000 dropping off registration tags tomorrow as it has only been on the dyno. Needs some street time.

        Probably 350 since full build, I actually put some street miles on mine last summer. Hell the event is like 250 miles from Stickys house, the damn motor will be broken in when he gets there. He sure has been changing his tune the past week or two, back peddling on his CLK race prediction now he is being a little girl about running full boost on Sunday, four days from now when he says he alredy has 600 plus miles on new motor. My guess Gintani does not want him to run me, after what you CLK did to a Gintani car in that roll on video a couple months ago they are probably still licking their wounds.

        What I do to Stickys car this weekend with the CLK will make that M5 anal rape video look close....this is going to be so $#@!ing EPIC!

        I really don't care what you have to say when you don't understand what is going on. You might as well stop typing I'm sick of the constant negativity and putting people down.

        I seriously don't care what you do or don't do with your car. Now I'll just skip this event entirely just to show you that this is happening on my schedule, not yours.

        Cool great story you already had a built motor that doesn't apply to mine whatsoever. Do what you want with your car and I'll do what I want with mine. It doesn't concern you.

        Pussing out? I would not expect anything less out of you and Gintani at this point.

        One more thing, Quit talking to me like I am clueless, this is the first $#@!ing car you have ever built and you act like you are an old pro. I was having race engines built before you could drive. This isn't my first rodeo bud and I can spot stalls and excuses a mile away. Boost up the $#@!ing car and line up with me already. I want to embarass you in front of all the idiot fanboys that think your car is in the same class as a Weistec CLK.

        so what type of "low boost" hp numbers you seeing, 600 whp? 700 whp? Throw us a bone, give me something to make me nervous.

        Come on people, keep on negative repping me....you pricks can do better than that, get me down to 0 by tomorrow morning and I will be impressed then I won't have any reason to hang out over here. Sticky wants me down below 100 so I can not post the rape video of me bending his csr over this weekend....if he even shows up that is.

        Sticky is King, Gintani is King, BMW is King !!!

        As soon as you quit acting clueless I'll stop treating you like you are.

        Sorry, I have no desire to have anything to do with you. Take care and leave my thread alone.
