    • 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.

        Your the one who says youll show up to all these events so id assume based on what YOU say that the cars timeline will follow....So since you said youd be at No Fly Zone and Shift Sector (this year and last year) I can say based on your word your car will be ready for the event....Just like when you challeneged Shiv to a race when you didnt even have a car and wasnt ready...Seems like one hell of a BENCH RACER to me....Im only asking for info based on what your bullshitting self has posted up..Stop bullshitting then...LOL doesnt seem you can



        Now this is insult to injury....HAHAHA



        BAHAHAAAH there is no hold up keep telling yourself this....shut the $#@! up with your bull$#@!....What world do you live in...??

        YES you wrote yourself this would be done in 10 weeks on the first page....NO HOLDUP!!!???? Hahahaha your a joke man...Dont bring up the DCT bull$#@! I really dont care...At least be forthcoming then you woldnt have to be so defensive and spew off bull$#@! about making it to events and races...

        This makes no sense.

        8400 rpm is a way low limit, ya for sure.

        I said I'd race either. I don't get why you won't like you said earlier.

        I'll run pump gas if it makes you more comfortable for the C63.

        Obviously they got the motor in, the trans needs to go in, then the lines, meth, trans cooler, etc. It doesn't take a few hours like some think it does.

        But what was wrong with your post is you said the s65 wont make that power because of "displacement alone". You did not say revs. Oh and there are BMW 2.5- 3.0L making that power. I wasnt referring to imports

        I love how Sticky keeps diverting back to my C BS for a race, the only race he is getting is with my CLK
        .....36 + months for under 750whp LOL Click here to enlarge
        I see what your saying and if it is the case then i can see why your breaking so much.... but i dont think this race will ever happen unless it is a twist of fait

        No it really doesnt. Not with modern cars with miles of wiring and no space. Question; why didnt they install the trans before installing the engine? Its much easier when the front of a car comes off tho im not sure with e90'S

        Because he is not going to be able to get a 4 liter spinning as fast as a little Honda 2.5 therefore more displacement is needed. There are several ways to make home but hands are tied when you are dealing wit a big V8. Show me a big V8 that revs to 10,000 rpm and don't Tell me an Indy car.

        I always thought a 4.0 was a small V8?

        You should not have to wait too long to see this race go down, if his car is running this week and broken in next week there will be no delay. My cars will be in California for another 2-3 weeks so we can line up at Shift Sector and then we can head over to Famoso for our 1/4 mile money race.

        After that the ball is in Sticky's court becuase the cars are being shipped back home to Chicago and he will have to come out here to run. My cars have been in California all winter, not my fault his car is not ready tro line up.

        See my previous post, it could go down in the next couple weeks if he is ready. I can not wait to drop the bomb on everyone about my winter build LOL....Sticky is so clueless, best part is it was right under his nose at No Fly Zone and he did not even notice.

        Sandbagging 101....nobody is wondering how my 660whp Click here to enlargeC BS was spanking cars with 800-1000 whp? Or how my CLK was even in the same frame at that nearly 1000whp GT-R? Sticky has been played LMAO!
