The limit to the standard clutches in the DCT box is 596bhp/450lb/ft torque.

Not sure if that it is flywheel or wheel power. But up-rated clutches can be installed.

My current setup on my smg is single mass flywheel and Kevlar clutch, I love the redline shifts but I hate the purposely delayed shifts of lower rpms, seems like BMW thought it would be a great idea for a luxury sedan but that surely backfired!! Why can't the smg shift faster in lower rpms like the Aventadors gearbox... hopefully when I get the fast Attack Motorsport tune they will make this possible, if this dct works and we have video evidence I will definetely be considering that down the line!!!

What's the weight difference between the OEM dual mass flywheel and your single mass? did you have issues doing the adaptations once you installed the single mass? I am considering do this also.

Thanks for any information you can add.

Yeah the shop had to keep doing the adaptation and they had to alter somethings to work 100%, the weight should be about the same, maybe a little lighter, but I wonder if we can go much lighter, like to shave 10-15 lbs off if it is possible, I haven't seen anyone with a light weight flywheel on an s85 yet.

The Kevlar clutch is way better than the OEM clutch and flywheel. That's what I wanted to do before but I got the DCT transmission for a steal and couldn't pass on it while I had the chance. I can't wait until my car is fully finished so I can show you guys the DCT on my S85 V10 M5.

I hope to see it as well. Strange to me the conversion is so secretive. I would think they would really publicize the success.

I will show the finished final product for sure. It's just I don't have time to visit the shop to get some pictures of the build. I can't wait till I get the call saying it is completed.

2 more weeks to go is it??

They started this Monday (2/13/2017) and told me it would take roughly 4-5 weeks brother. I dropped off the car last week but they were so backed up and literally didn't have any availability until Monday (2/13/2017). I am impatiently waiting for the build. I will call them these couple of days to check the status.

I thought the e9x M3 final drive was 3.15 on the DCT car.

These below are based on 3.62 rear end and standard 285/35/19 tires. They are within a couple of MPH either way.

EDIT: formatting does not work too well on here with the spacing below.

It is but I used 3.61 as no-one mentioned changing the diff ratio in the thread. Otherwise just use the E9x data.

Maybe the programming will fix this, would love to know.

Not unless they've figured out way to reprogram the DSC as well. One set of wheel speeds directly feed the DME, another set is transmitted over PT-CAN from DSC to DME. Not likely anyones altering DSC module code, it doesn't have separate calibration area like the DME and no A2L (map file) is available; all changes would be made in program code via reverse engineering the disassembled code.

Way easier to swap the rear ratio and keep everyone happy.

 

[tjav8b]

So, someone doing a DTC conversion would also run the 3.15 rear differential?

Makes sense to me. Keeps the engine and DCT operating in the range it was designed for.

Update! Called to find out the status regarding my car and they said they are waiting to get my custom fabricated drive shaft back to continue and install the DCT. I'm impatiently waiting to get updates and want to inform you guys as soon as I hear anything new.

What rear diff ratio are they using?

Great question Bucky. I will call and ask later on to find out what rear diff ratio they're using. What do you personally think they would be using?

Who knows what they will be using. Going by discussions on here they can only use the M3 DCT diff ratio but I would love it for the to use the standard M5 diff ratio. This is the interesting part along with the transmission programming.
