interest in a carbon fiber drive shaft?

the Drive Shaft Shop in North Carolina and I were asking "what if".

For my '79 300SD Turbo Diesel, a carbon fiber drive shaft would cost approximately $1,500.

Stronger, lighter, proven to 2,800 horsepower.

If there was a group buy ...

Talking

I wonder if the URO flex discs will support a 2800 HP OM617

I think that should be the basis of the group buy. LOL

But only if a URO guibo is included in the deal...

How much does a "normal" drive shaft weight? This is a very interesting idea and a group purchase might be able to include variations on the same drive shaft...

The driveshaft on a 116 300SD is listed in EPC a couple of ways:

The entire drive shaft with ends and center is A116 410 72 06 independent of year. According to EPC the drive shaft for a 300SD is unique to that car.

For a 6.9 the part number is A116 410 69 06, that that would be for a LWB car. According to EPC the driveshaft for a 6.9 is unique to that car.

Which makes me wonder what is different about all SWB cars vs. all LWB cars...

450 SE : 58 06
450 SEL: 59 06
280 S: 57 06
280 SEL: 68 06 or 67 06
350 SEL: 11 06 or 12 06

So what is different?
Looking at the separate components...

Back to the SD
Front drive shaft is 116 410 41 04 - unique to the SD
Rear drive shaft is 116 410 04 07 - also unique to the SD

And for a 450 SE
Front: 29 04 - unique to 116.020 and 116.024
Rear: 82 02, replaced by 81 02, replaced by 97 02 - which is common to 032, 033, 036 as well as 107.024

so the possibilities are endless. My question would be is the carbon fiber drives shaft a single piece or is it a two piece drive shaft? And is it strictly based on length and end fittings, or are their other concerns...

I think there would be a market for such a part, and that the market would be far greater in the W113 cars as opposed to W116 cars...

My thoughts also, and why not hit the 300 SL crew as well if nobody is making the part already for those cars. Maybe the rally guys would be interested as well, there are at least a couple of rally Fintails out there presently.

I'm pushing over 3,000 HP with my engine after fluting the turnbuckles and porting the shenanigizer, so I'm out on this buy.

I'm wondering why the HP is a relevant issue. Isn't it more an issue of the torque placed on the drive shaft?

If there was a group buy ...
Max Engine Torque = 180 ft/lb
Max transmission multiplication = ~4
Has 720 ft/lb been twisting the production driveline?

If it ain't broke,....!

my main interest is the weight saving, relative bullet-proof nature of CF and that the manufacturer is highly respected.

i used to own a 2006 Subaru STi and one of the most recommended upgrades was a CF drive-shaft ...

lose weight, gain a little mpg

if i won the lottery, after paying the mortgage and setting up college funds for the kids ... ;-) this would be an immediate upgrade.
