• 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.

        Are you going to run a cog set up with it ? Doing so will help with belt slippage.

        Getting the car back from SSP to Gintani. Installing a supercharger and then tuning it.

        How many ribs does your serp set up use now ?

        By the way, that is anodized aluminum. The color going in my car will likely be red but various colors are available.

        Do you think it will be running this year?

        It's beautiful.
        How they paint those pans? Electrostatic coasting?

        Yes:

        Anodizing, or anodising in British English, is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called "anodizing" because the part to be treated forms the anode electrode of an electrical circuit. Anodizing increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than does bare metal. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light.

        It's SSP and the clutch pack upgrades are already available.

        My transmission isn't a kit, it is a one-off high torque build specifically for me.

        I sold my SC so I'm buying a new one and if it was back on the board would definitely know.

        I'm waiting on SSP to wrap it up and bring the car back to Gintani. I was hoping that would be this month...

        Sticky,

        I would love to see the results.

        If the upgraded /modified DCT can hold 40 psi + 400 shot (lotss of torque) it will be great Click here to enlarge

        Will you be spraying a 400 shot Click here to enlarge
