    • 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.

        Sounds good...from the way your post was written, I thought something more was forthcoming from you.

        I'll be on low boost. Shift Sector will just be shakedown runs for me before I hit the strip.

        Don't concern yourself with the negative people here. I'm just glad some people appreciate it and are man enough to say "congrats." I've been waiting a while, glad we're about there.

        It's fine, going to be great for myself and the forum. Let's see what I can get her to put down and then I'll be ready for magazine covers. The master plan is all coming together Click here to enlarge

        If Sticky commits to Wannagofast , I will rent Byron and Autobahn a couple days before the event so we can have a head to head shoot out.

        This is the whole plan the whole time. My car is being broken in. I can't run full boost yet. We need to make sure the tuning is spot on. I'm just running shift sector for fun and to put the fear of god in ESS M3's.

        I will go to Chicago. We'll do a full shootout with a camera crew for when I expand my network and launch a youtube channel, and everyone is happy. Maybe you'll even get $1k for your trouble.

        Congrats man! Been following this thread the past few months and its nice to see everything is coming together. Can't wait to see what this thing will put out and the DCT build is so sweet. If I decide to take my M3 to the next level I think this would be a must. If you're ever on the east coast with it I'd love to see how much faster it is on the street compared to mine. Man I'm excited for you - *should* be the fastest e9x m3, correct? I think some of the VT3 guys dyno in the high 600s. I don't know about some of the other Gintani builds that don't have much detailed info online...

        VT3's make me LOL. They don't offer much over a stock internal car. It's really no comparison.

        Sure no prob I'll be on the East Coast at some point most likely for a roll on event.
