• 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.

Only thing is i have a non P31 engine without the forged pistons(i have cast pistons) and lightweight connecting rods/ crank even tho they are forged steel on the non P31 as well just not "light weight"

        My question is how much power/boost can i run on the non P31 C63 coupe with MCT ? is it the same as JRCarts BS does the "sls" internals give more strength or is the non P31 engine strong enough to hold up to the point that the transmission needs upgrade
        Seriously these questions are for the M156 section... please create a new thread on this topic it doesn't belong here.

        Not angry just don't expect to get your questions answered in someone else's build thread... please put those topics in the correct section for them.

        What I mean is that Weistec is known to be conservative and to understate performance levels rather than chest pump.

        But didn't you guys post actual dyne graphs showing 870 whp i don't get how that can be under stated since a reading can't really be altered its whatever the car put down

        I think you mean they're conservative with their tunes, not their numbers. It would make no sense to understate produced numbers.

        You missed the boat on my comments.

        Anyways sticky is actually trying to moderate (of course the only reason is that it is his thread) so let's not give him another reason to be upset.

        BTW my post had nothing to do with the comments between you and Sticky. Wasn't trying to say that you would be afraid of a 1000whp M3. I was saying that with my goal being DCT & 1000whp, by the time Benz has a DCT which I would consider buying, there will probably be just as fast or faster M3 options out there.

        Sticky I hope your car is ready soon and can hopefully put out some nice numbers. Beating that C in a straight line is going to be a challenge...

        I'll start playing with you guys next year when it's either ~1000whp DCT or TT Gallardo time. Have been keeping an eye out for a low milage already done up UGR...
        No reason to overpay for a used TTG They average 10-15k more then buying the car and having it done.

        I thought only Saturday was sold out. Let me make a call, I can probably get you in.
        I might be able to help too. Let me know. I am running sat as well.

        Most of the R package cars we were playing with at tx2k were 1800whp +

        they are conservative with their numbers. I have seen it first hand. Plus if their blower says it will make x and doesn't they are in for a marketing nightmare.

        Figured you'd know the answer to this since you're familiar with the UGR TT-Gs... How hard would it be to convert an E-Gear Gallardo to a 6-speed? From what I've read the transmissions are identical, except for obviously the clutch engagement.

        I've just noticed that 6-speeds are incredibly rare & Lambo's already announced all their cars from the Aventador on are going to be automated, F1 style gearboxes

        Just a lot of work. I personally would never do it...the Egear is just soooo much fun. Unless you have driven one you just don't get it!

        @Weistec
        The stock transmission becomes the weak link at a certain point, even the MCT. Not sure what the non forged internals can handle, my CLK is running the Weistec internals and my C BS has the P31 internals. I will try to find out or have Weistec chime in.

        This will be my last post concerning Weistec stuff in Stickys thread. If I am not mistaken the highest grapgh Earl or I posted was 830whp but that was last year..we are WAY beyond that now.

        Sorry Sticky, I will keep on topic
