    • 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 love how Sticky keeps diverting back to my C BS for a race, the only race he is getting is with my CLK
        .....36 + months for under 750whp LOL Click here to enlarge
        I see what your saying and if it is the case then i can see why your breaking so much.... but i dont think this race will ever happen unless it is a twist of fait

        No it really doesnt. Not with modern cars with miles of wiring and no space. Question; why didnt they install the trans before installing the engine? Its much easier when the front of a car comes off tho im not sure with e90'S

        Because he is not going to be able to get a 4 liter spinning as fast as a little Honda 2.5 therefore more displacement is needed. There are several ways to make home but hands are tied when you are dealing wit a big V8. Show me a big V8 that revs to 10,000 rpm and don't Tell me an Indy car.

        I always thought a 4.0 was a small V8?

        You should not have to wait too long to see this race go down, if his car is running this week and broken in next week there will be no delay. My cars will be in California for another 2-3 weeks so we can line up at Shift Sector and then we can head over to Famoso for our 1/4 mile money race.

        After that the ball is in Sticky's court becuase the cars are being shipped back home to Chicago and he will have to come out here to run. My cars have been in California all winter, not my fault his car is not ready tro line up.

        See my previous post, it could go down in the next couple weeks if he is ready. I can not wait to drop the bomb on everyone about my winter build LOL....Sticky is so clueless, best part is it was right under his nose at No Fly Zone and he did not even notice.

        Sandbagging 101....nobody is wondering how my 660whp Click here to enlargeC BS was spanking cars with 800-1000 whp? Or how my CLK was even in the same frame at that nearly 1000whp GT-R? Sticky has been played LMAO!

        It is, when compared to other performance V8s -- Mustang's 5.0L V8, the AMG 6.3L V8, the SRT 6.4L Hemi V8, and the various GM V8s (5.3L, 6.2L and the 7.0L). This is nothing new though, since BMW has always done more with less, targeting 100 HP/Liter with their motors. The S65 (or S85) just isn't even remotely close to being as "boost friendly" as the S54/S62.

        Nothing you will have to worry about. Your car will be in another zip code once we hit those cones to go. But yeah I'll be racing

        You can't appreciate the engineering marvel of extracting more from less?
