Are they going to show you a working S85+DCT combo when you drop off the car?

No.

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?

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.

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

 

[leoinsd]

Will top speed be different?

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.

S65 revs even more than the S85.

S65 revs even more than the S85.

What do you mean by revs more? My S85 revs to 8600.

Stock redline comparison.

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.

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