• 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 am not going to call them, I will let someone else do it. I will go ballistic on them and they will never finish his car out of spite.

        I just want to race Sticky and beat him so he maybe then realizes this entire build was a giant wast of time and money. While they are playing grab ass over at Gintani Weistec is upping their game on my CLK, I will be in the 9's before Sticky is in the 10's LOL....and he thinks he has something for me LOL

        Maybe a verbally abusive phone call is what Gintani needs to get this build finished.

        I would be shocked if Gintani let a random person influence their desire to finish Sticky's build. However, a swift kick in the ass and the awareness that the masses are carefully scrutinizing Gintani's project might light a fire under their ass.

        If nothing else, it will at least give you an opportunity to find out more information as to why the build is being delayed.

        As much as I like to disagree with Sticky...this isn't our fight. His money so his problem (although the very first post here seems to indicate the build would take 10 weeks). That post was 31 Mar 2010 which is about 154 weeks ago. Click here to enlarge

        Still no news? I wish I had Sticky's patience....or maybe I don't, actually.

        Chicago is too freakin' cold. The fact that you WANT to go to Chicago proves that you are crazy.

        Lets just say some people I know know exactly what is going on behind the scenes, people jump around from job to job, company to company and with that information transfers from person to person. If Stickys car is not done soon I might just spill the beans myself.

        LOL, I doubt it if it makes him look like an idiot. Seriously though, I'm just waiting until the Shift S3ctor event to see if the car makes it. I'm just sitting on the bench right now.

        I know one thing for sure, both my cars will be at Shift Sector and I will be keeping my fingers crossed that Stickys car makes it but my more realistic side knows his car most likely will not be there, its less than three weeks away at this point.

        No no, I wish my car lol. My turbo won't even be ready until next week anyway. I've already paid for everything, once I get some pics from my tuner for my build I'll start another build thread lol.

        I was originally talking about Stickys car being ready. I really wanna see it do some action esp vs C36 BS Weistec Stage 3 and the Ess VT3.

        I'm hoping to as well man. There is going to be another event in May at the same Shafter Airstrip. Just letting you know that there is more back up, just in case. Click here to enlarge LOL

        May lol, my cars are going back to Chicago right after Shift Sector, I have Road America track day in late April, Autobahn trackday in May, drag strip at Byron in April and May and a 1/2 mile airstrip event in Chicago in early June. Also probably going to register for the Goldrush Rally this week . Sticky can come to me if he wants to race.

        FYI, I am notmracing Sticky with the C BS, unless he wants to run on a road course, when I run Sticky he is getting the full CLK beat down, I want to really embarass Gintani..

        Wow! That's a lot of keyboard engineering for one thread, don't you think? The way I see it, the only race that would be fair at his point is if someone else tried to build an E92 M3 to the level of this build. Who builds it the fastest? That would be cool. Who cares if it is not THE FASTEST CAR EVER on the street/strip? There is always a bigger fish in the pond. Are we to deduce that there is only one car in the world that is not junk since there can only be one car that is the fastest? This is not a Honda Civic that he is building where all the R&D has been done and parts are already available, it is probably going to be the most powerful and fastest E92 M3 out there, and that's something! You want to beat him in a race? Buy a car and go through everything he has gone through so far and build a faster car. Any other comparison is stupid when you are pushing the limits of a platform like this. The god damn block is flexing! Wrap your head around that!

        Tho, this is impossible since the roadblocks have been cleared and knowledge is publicly gained. You're suggesting someone pain themselves with the same mistakes with zero knowledge of this process, yet having to make the same upgrades or better upgrades. If the builds were began at the same time and upgraded to the same degree, then this could be a possible comparison.
