• 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 doesn't the shop simply admit they can't get the job done and put an end to this torture.

        What kind of an attitude is that? its up to sticky and sticky alone to decide when enough is enough. Just think about what this will do for aftermarket bmw if all this time and effort results in a bullet proof DCT. This is what the industry is all about IMO. Overcoming the impossible. I hope his m3 destroys all you haters on the track some day. Good luck Sticky!

        That seems about right if you followed this thread from the start...

        Don't get me wrong, I REALLY hope this gets done and performs as announced. But you have to be REALLY optimistic to keep the faith...

        Tuners wil probably have modded versions of the GM 8 speed DCT on the road before Sticky gets his car back.

        The GSP/287/Turnpike (all of them are in Mexico BTW) will be torn in half from the power of those two cars running against each other.

        What level? There is no car on the road&no numbers have been posted so no level has been reached.

        True That! Gintani has really raised the bar on this build......NOT! The bar has been raised to such a level that a double amputi hamster could hurdle the bar from what I have seen.

        This is such a stupid comment I won't justify it with anything further.

        Ya General Motors finally getting a dual clutch trans (that still isn't in any cars) is somehow equivalent to aftermarket dual clutch development. What a burn....

        Correct me if I'm wrong but,is that YOUR car? Sticky I'm a bit disapoint in your ricer math. I stand by my original comment.
        Unless of course your comment about no one reaching this new "level" was not directly aimed at your car but just in general.
        Why so nasty with your reply? Damn bro...

        I am just hoping that all this ribbing motivates Sticky to be up Gintani's ass on a daily basis, it's a shame what has happened here. Now sticky is not only getting mad he is also delusional because he seems to think that if his car ever gets completed its going to run with Earls car and mine......that's some funny $#@!.

        The worst part is Sticky is constanly making excuses for them.....he is like a battered wife that accepts getting slapped around by her husband and them makes up lies and excuses to her friends about how she got that broken nose slipping and falling in the shower and how she hot that black eye when she bumped into the wall walking in the house at nugt with the lights were off.
