    • DCT Build Part VII - Taking the BMW E92 M3 DCT to the next level, 800+ wheel horsepower clutch disc capacity

      You have seen the DCT taken apart, what it looks like inside, worn clutch discs, and brand new higher capacity clutch discs made. The new discs handle 600+ and 700+ whp respectively. With my power goals, SSP has decided to build a clutch pack that is beyond anything developed at this time for the DCT. What is the power goal? Well, it is beyond what is currently available and SSP is currently developing a clutch disc pack capable of over 800 wheel horsepower.

      How is this being done?

      The current clutch discs are of a thicker material than the stock discs. However, the stock clutch pack has 9 discs in it. By increasing the number of clutch discs they are going to increase the maximum torque capacity. By going to a thicker material and increasing the total number of discs to 11, the DCT in the BMW M3 will be taken to a level no one previously thought was possible. This is going to be similar to the GTR 1000 hp clutch setup by SSP (pictured) but the GTR uses more clutch discs albeit smaller, thinner discs.

      What else is being done and how much time will it take?

      The DCT is going to receive a cooling system based on what SSP has done with the GTR's. This will be a DCT specific application and will be great for the guys who track. No more overheats, no more staying away from the track on hot days. Look for a separate build thread specifically for the cooling system in the next few weeks. Regarding the time period, expect completion next month with the car returning fully assembled and capable of handling the increased power.

        Last week we brought you the initial pictures of the build process for the DCT oil pan. You saw one side of the pan and some users asked about seeing the other side. Well, here are the final machining photos revealing the completed pan. As you can see, there are fairly deep fins cut into it for cooling as well as a custom M logo specifically for the BimmerBoost M3. Hey, that's how we roll.

        No, the motor will need to be installed and Gintani and I will need to figure out what SC setup to go with. I would be lying if I were to say I'm not concerned about the built motor SC as there still seem to be issues to work out and we were thinking of getting pretty crazy with my setup.

        I'm hoping by the time the car is back we will be ready to rock. I am thinking I will go with a big boost YSI, it will make the most sense but there is no proper running YSI setup yet. I really want that blower though...

        excuse my ignorance but whats so special about a ysi as reguards the normal vortech blowers?
        i no everyone loves turbo setups but honestly to me a properly setup centrifugal just rocks, i love that fact we keep that ///M throttle response.
        Man i drove a z06 with a vortech setup and HOLY $#@!........... power EVERYWHERE in the rev range, truely awesome thing to drive.

        YSI is just a vortech blower just a bigger one than the T-trim, much bigger.

        Looking good sticky!

        That machining work looks great. I would've carried the fins to the edges of the M logo though. Follow the contour. That's just me though.

        You going to MFest? If so, I'll have to take you for a ride in my car. Click here to enlarge

        I'm surprised that with all the work being done on the car you haven't found a way to turbo it rather than using an SC. But still can't wait for the final outcome. Good luck.

        Turbo would just cause way too many headaches, someone else can do that.
