im not sure if it does anything. i have it on some cars too. im sorry i couldnt be of more help to you.

It should increase acceleration, as the writing on the screen normally informs you. If you dont think it makes a difference, go to the drag strip, and do a few runs without the carbon shaft fitted. Then attach it, WITHOUT changing anything else, and you should find your time is quicker.
With any driveshaft or propshaft, the loading is mostly torsional, since it is trying to transmit torque from engine to axle etc. Since torsional rigidity is a function of radius, a larger radius is stronger than a smaller one. To this end, a solid shaft can be bored out, since the centre has little do to with the rigidity of the shaft. This, combined with the lightweight material, makes it lighter - and by Newton's 2nd Law the shaft will accelerate quicker. This gain is transmitted thru the drivetrain to your wheels.

like the flywheel options it reduces the spinning mass in the drivechain. this equates to less resistance for the engine to turn over which means better acceleration. I highly recomend this and the flywheel as upgrades.
however by doing this you do make one sacrifice. when coasting your car will lose speed faster as the centrifugal forces are less because of the lesser mass. this generally doesnt matter when it comes to high acceleration and hard braking circuts

It help me come out of turns a bunch, it kicks up the rpms faster when your in low rpms

*sniffle* That was beautiful... I'm so used to Southern California beach brats and college freshmen in new mommy-bought Jettas that to hear more than 3 big words in a paragraph brings tears of joy to my eyes...And I shall call him Bill Nuy the Science Guy.

Wow thanks... didn't realise a bit of proper engineering English meant so much.
I've got a racing flywheel in my RL vette. And it sure is nice. I hadn't expected it to make as big a difference as it does. It's not a lot of lost weight as far the total car is concerned. But you have to consider that the drive train has to be accelerated to much higher speeds than the rest of the car. A pound dropped off the parts that spin is worth _a lot_ more than a pound dropped off of anywhere else.
Some claim it's typically a 10 to 1 ratio (!). That is, dropping 10 pounds off the drive train is the equivalent of dropping 100 pounds off the rest of the car.
Any parts in the drive train you can lighten are a big help. Inlcuding the drive line.
Now here's something you may not have realized. It doesn't just help acceleration. It helps braking, too. Remember... the brakes end up having to halt the inertia in the drive train, too. With a lighter drive train, the car will speed up _and_ slow down faster.

thanks skant. yeah the lightened drivetrain doesnt hold its momentum as well as a heavier one as the centrifugal force are further out on a heavy flywheel. think of it as a merry-go-round. start it spinning by hanging on to the outside and running. the move into the center and it picks up speed

Centrifugal force doesn't exist!! It's merely the reaction on the centripetal acceleration (i.e, the acceleration toward the centre of the circle, when anything travels in a circular path). Anyway, that's irrelevant.
The reason why a lighter flywheel doesn't hold its momentum as well is simple. Momentum = mass x velocity - thus a lighter flywheel, spinning at the same speed (angular speed here - if they are of different sizes, the actual velocity will vary according to the radius you measure it from) as a heavier one, will have less momentum.

Jmac279*snickers* You said shaft
Must you be so immature?? I should point out it should read "carbon FIBRE"

So is it ever a bad idea to purchase this or Racing Flywheel etc?
Or is it always good to buy if you can?
The example of someone above going from 10.2 to 10.0, isn't it possible that you just hit the gas .2s late or something to that effect and not the carbon driveshaft? Not that I'm saying that it didn't do anything but I wonder sometimes.
