• 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.

        Here are pics of the car after SSP started on it after it arrived, more updates after the holiday weekend and expect updates on a regular basis as they finish this. What you see here is the transmission out as well as the factory cooling system which is being upgraded to basically the same cooling unit they use on the GTR. The area in the passenger side front is where it will be mounted, they measured, it fits:

        A while to go, we will hopefully be getting some more concrete updates from SSP after this weekend. I'm interested in the cooling system as well as the new clutch packs with 11 discs. They will handle a lot more torque... and they will need to Click here to enlarge

        As of right now, the transmission is completed and the cooling system is in the process of being completed. Where we left off was the car being taken to SSP for the build of the cooling system. To make this all make sense we will not skip ahead, instead showing you each step. Here SSP is getting ready to put it together with the new clutch discs. They laid out all the parts and used 3d scanning equipment to record them to aid in the production of the parts. Everything was laid out to make sure the parts were clean and accounted for. Additionally, they were working on prototype viton seals for the transmission. The next update will have details on the cooling system.

        They just need to finish the cooling system and they will bring the car back to Gintani who should be in the process of completing my low compression built motor.
