Anyone try the MSA aluminum driveshaft?

Im considering an aluminum performance shaft since my slip yoke is no good.

Thanks!

I guess I'll play guinea pig! ahah

Dont know anyone who has used one. Why do you want to go aluminium?

Plenty of other ways to reduce weight and cheaper per ounce. Ligthening the flywhel etc.

They list a carbon fiber model. Go with that if you want to spend that kind of money...

Go to the junkyard and buy a used drive shaft for $30. Put your $ into something that would ACTUALLY boost performance, like a better exhaust system instead of something shiny on the bottom of the car.

Do you have any idea how much of a weight difference there is? If there is a significant difference then it might be worth it (in my mind). This is not a static component, it's rotating so there would be an added benefit. I have a feeling, though, that this is the type of component upgrade you make when you are going for a track car and have already tweaked everything else. If you do make the change please post some results. I'd be interested to know how it works out.

I would think the reduction in rotatonal inertia might have a bigger impact than the weight savings. Similar to a lightweight flywheel. Would be pretty easy to calculate. As mentioned above, it might not be the most bang for your buck.

A driveshaft doesn't have much rotational inertia to begin with. Since it's long and skinny, the location of the mass doesn't stray far from the axis of rotation.

I agree, the radius is relatively small, but they are also made of steel, and constantly accelerating / decelerating... My comment was simply that the weight savings probably has less impact than the rotational energy savings.

Either way, it's not even worth doing the calculations. Like I said, there are other items / improvements that will provide a better bang for your buck.

Julio, I completely agree. Just adding some extra info...

Let us know what you think of it. They look pretty nice. Pricy but hey, I don't know what it costs MSA to have them produced so I can't judge it.

Lowering the rotating inertia weightl allow u to put a little more power to the wheels. So my slip yoke on my sdriveshaft is bad. Instead of getting a used part. Id rrather go with an upgrade. My car is far from stock at this point.
