• 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.

        I swear, people just love talking out of their asses hahaha every CNC machine I've ever seen uses a ton of water just like that.

        Congrats on getting one step closer on this transmission build, Sticky, have you been without your M3 for all this time or do you have a spare transmission?

        I've been without it and surviving somehow. Longer than 7 months and I'm not falling apart or running to another company or anything.

        It's a necessary sacrifice for the benefit of the community. I don't mind, people whose opinion matters to me know I have an M3 I am building, I'm comfortable with it.

        Not everyone knows all the details as a lot of guys just focus on their particular platform.

        I found this thread through a posting on M3Post....and now that post has been taken down. the work going on here is extremely beneficial and it's a real shame it's not appreciated on the other site. Seems like a lot of misinformation going on about DCTs so it only makes sense to share the intel. Oh well.

        Thanks for exploring the inner workings of DCT, makes me feel better about my choice.

        They are in the dark ages with DCT info, their own fault.

        Glad you found it, feel free to share with others.

        SSP has not revealed final pricing of the cooling package yet. I am waiting on that (as are others) and as soon as I know an announcement with the package, pricing, and what is included will be made.

        As of right now, all that can be said is it will be under $3,000.

        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...
        The YSI blower is no joke would be nice if you can make it fit,that blower is the big dog as far as small blower's go.
        Good luck with your build man today is the first time I saw this thread lol, had to jump in I like the direction your going in.

        Appreciated and yes, I intend to definitely try the YSI. I won't accept any smaller blower than that, will be a beast with it.
