Update! The transmission will be at the shop tomorrow and hopefully I will drop my car off next week.

 

I have a feeling this thread will be quite long.

 

Yup same here

 

Its been 2 weeks

Did they finish the russian car?

 

Haven't been at the shop. I'm going to go most likely next week to drop off my car.

 

Does anyone know what trans BMW put in the M5 CSL? Was it an off the shelf M3 DCT as Dinan plans to use?
Honestly, I don't see this happening.

I always heard about this but no one has ever posted any good videos... I wonder how this one will go.

 

Dropped off car today the build will start next week.

 

Updates Updates.... we need Updates

 

Did they have an S85/DCT there to show you?

Honestly, I was on my one hour lunch break from work and dropped off and left security deposit and left to get back to work immediately.

 

Doesnt it make you uneasy not seeing one working when people have wanted this for years!! Apparently there is 3 done already but no one knows about it??? I doubt anyone could keep there lips sealed that much
Gintani would have a backlog of years for dct conversions if that was the case
Its the single best mod that people would froth at the lips for!!!

I wish you luck

 

I have no issue or concern with Gintani about the build. These guys are great at what they do, I personally haven't driven a DCT EXX M5/M6 but know that these guys are the only one who can do what they say they can build. Until now their supercharger holds records and now they are slowly but surely finishing up with the twin-turbo kit that's going to be pushing over 1200hp easy. I haven't seen that type of build from any other company for the M5/M6. We are all impatient to see the final project completed! As far as my transmission goes; I can't wait to get it back and enjoy that smooth and instant shifts on the DCT without having the issues that SMG has.

 

It's so good to see you Dinan with all of that happinessabout this upgrade, I wish you all the luck that you can get.. hehehe.

And what's the total cost of the DCT transmission upgrade?

Thank you. If you want to find out how much it costs please contact Gintani at (818) 787-8260

 

Out of interest - any written commitment on what they will do? Care to share? Not looking to see $$$ or the like.

I know Gitani is a reputable company and can do some pretty awesome stuff.

 

What is the difference in gear ratios between the DTC and SMG?

I'd also like to hear more about Gitani S85 supercharger records that they hold.

 

BMW M3 DCT

1st 4.780
2nd 2.933
3rd 2.153
4th 1.678
5th 1.390
6th 1.203
7th 1.000
Final Ratio 3.154

E60 M5 7SMG

1st: 3.99
2nd: 2.65
3rd: 1.81
4th: 1.39
5th: 1.16
6th: 1.00
7th: 0.83
Final: 3.62

 

Do those ratios mate up well to a peaky revving S85?

 

They are a lot shorter, lower top speed so it could be like a diff change. I would have to work it out to see the equivalent diff ratio, too busy at work at the moment but its a quick excel spreadsheet.

 

Will top speed be different?

DCT diff ring and pinion will fit on an M5 carrier. One would hope they've taken that into account or DSC and DME will flip out

 

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

 

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.

 

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.

 

Russian m6 car so no one has yet to see...

 

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?

 

any news?

 

Two weeks. haha

 

As soon as they finish the 3 year motor rebuild there are right on it

 

Update

Got a call from Gintani. They said it should be complete by the end of next week. After I will post my SMG pump and transmission up for sale on the board.

 

Once you get your beast back hit me up, i'd love to go for a ride and see what DCT feels like with the S85. I am actually dropping off my car at Gintani this friday for some preventive maintenance and new clutch and flywheel
