carbon fibre driveshaft (propshaft)

[Albert]

Did any of You heard of carbon fibre driveshaft (propshaft) being made for Audi S2 ?

Lot of rotating mass and lot of weight could be saved.

I want to make one for my self and I'm looking for possible solution for my track car.

Did search on the forum but did not find anything.

I have found a company in UK that does some carbon driveshafts http://www.torqline.com/

My Audi it's an racing car also. But with a smaller budget.

My freind has a carbon prop shaft on his R1 powered MNR (lotus seven kit car) it made a huge diffrence his words where it felt like he had gained 50 bhp..
But was very expensive.. I've seen scooby and evo props for £1200.

I don't trust in them...! For high torque engines is not a good option

So please tell us, why big turbo supra guys are still using them?

Believe it or not there was rumor on the 20v.org list that the US spec Audi 90 Q20v had a carbon prop. I've never seen any pics to back that up mind.

yes, I have seen that remark also but did not see any carbon shafts at all.

To have a true motorsport propshaft it has to be a single shaft with no center connector and bearing.

This is a true statement. My 20v Coupe 1991 has a carbon fibre driveshaft. Many others depending on VIN# and Year of production came with them also.

On Audiworld some of the guys have cut off their spline ends on their carbon fibre driveshafts and re-welded them to a hollow aluminum tube to make a one piece shaft with no center bearing.

This could be an option for you w/out spending too much for custom setup.

"Some reported the results being a little slower of the mark because of weight rotation loss but when in motion the acceleration was hugely improved and was worth the effort. "

i use to frequent a lotus 7 replica forum they had the general rule of thumb decrease a rotational mass and you multiply the difference by 3 to find how much less weight that is to accelerate, this was for wheels and brake istr, so before the diff multiply by 4 about to get 12!! they also use to say carbon was safer because it will blow up into dust before it snaps and cuts your leg off....
i have also herad about carbon props used on american spec 90 20v...

The stock prop is really not that heavy IMHO, probably 1/2 the weight of the prop off my old 200sx..
wonder why the Audi engineers would have specced a carbon prop for the yanks?

Tim Cooper has loads of carbon fibre props that have come from various rally and touring cars. Give him a bell.
