OnyxCobra Posted October 11, 2012 Report Share Posted October 11, 2012 I'm throwing around the idea of picking one up if I can find a deal on one, what kind of power are they good for? I've heard they aren't as strong as the stock ones and I've also heard they are stronger, does anyone know the real answer? Link to comment Share on other sites More sharing options...
AZSN95SNAKE Posted October 11, 2012 Report Share Posted October 11, 2012 I've also heard that they are stronger. Don't strictly dedicated track cars run them?I bought one brand new; haven't put it in yet though. Been sitting there for a month. Not much of a noticeable gain from them though, if that's what you are looking for. Link to comment Share on other sites More sharing options...
330CubeGt Posted October 11, 2012 Report Share Posted October 11, 2012 Less rotational mass is always better, but from experience I have seen nothing more then a E brake cable bracket rubbing the aluminum driveshaft and it cut it in half after some time.Im at the junk yard quite often and see driveshafts laying on the ground here and there and the aluminum shafts are always bent,twisted or broken vs. the steel shafts that are not bent etc etc. I have no interest in a aluminum driveshaft. Unless I find further information that proves them to be any better then the steel shaft... Just my .02Heads up and ass kickin!

ttocs Posted October 11, 2012 Report Share Posted October 11, 2012 I have been considering it for a while now. Anyone have links to where is the best place to get one? Link to comment Share on other sites More sharing options...
revhead347 Posted October 11, 2012 Report Share Posted October 11, 2012 I didn't know anyone didn't run an aluminum driveshaft. I think the strength is about the same. The motorsport advertises a higher torque capacity, but I think that is only because it comes with better U-joints. If you put stronger U-joints in your stock driveshaft, it will hold about the same.Kurt Link to comment Share on other sites More sharing options...
Number Tew Posted October 11, 2012 Report Share Posted October 11, 2012 Less rotational mass, quicker revs, better mileage, etc.Terminators have aluminum driveshafts. they hold up just fine. Link to comment Share on other sites More sharing options...
revhead347 Posted October 11, 2012 Report Share Posted October 11, 2012 I think it has more to do with the quality of the driveshaft then the material. I've seen those huge aluminum driveshafts on Suburbans bend all the time. I've never heard of a Motorsport drive shaft bending unless someone was putting some serious wheel lifting torque to it.Kurt Link to comment Share on other sites More sharing options...

OnyxCobra Posted October 17, 2012 Author Report Share Posted October 17, 2012 There seem to be quite a few on craigslist, I'ma try to score one for a decent price. Guess I should pick up a safety loop while i'm at it. Link to comment Share on other sites More sharing options...
iRoush Posted October 17, 2012 Report Share Posted October 17, 2012 Aluminum just allows less drivetrain loss, you don't necessarily make more Hp. I didn't notice a difference personally but the rotational weight savings is good for my setup. Link to comment Share on other sites More sharing options...
OnyxCobra Posted October 19, 2012 Author Report Share Posted October 19, 2012 well yeah of course the engine isn't making more power but you should be putting more power to the tires which is a power increase. Link to comment Share on other sites More sharing options...
iRoush Posted October 19, 2012 Report Share Posted October 19, 2012 well yeah of course the engine isn't making more power but you should be putting more power to the tires which is a power increase.it's negligible on the dyno. you may see 1-2% increase in power if at all, even that is a stretch.

iRoush Posted October 19, 2012 Report Share Posted October 19, 2012 you said the weight savings is good for your setup and then you said it's negligible, i'm confused.rotational weight savings. allows the engine to spin easier/quicker, not necessarily make more power.

OnyxCobra Posted October 19, 2012 Author Report Share Posted October 19, 2012 I understand that, it seems like it would be a direct relationship. Link to comment Share on other sites More sharing options...
revhead347 Posted October 19, 2012 Report Share Posted October 19, 2012 You get more power to the wheels where it counts. Like I said, most people do it because the aluminum driveshaft is stronger, not for power, because the power difference isn't that great. It's also a little more flexible, although no where near as flexible as a carbon fiber driveshaft.Kurt Link to comment Share on other sites More sharing options...
AZSN95SNAKE Posted October 19, 2012 Report Share Posted October 19, 2012 It won't give you any power. However, it will free up a few ponies due to less rotating mass and weight savings. Think of it like switching to an electric fan, its not producing more power for you its just freeing up a few ponies. Its nothing that you are going to feel powerwise. It will make your car more enjoyable as it will clear up any vibrations in the rear due to a gear install. It may feel a bit peppier revs wise but it may also be a placebo lol.

SVT Rob Posted October 19, 2012 Report Share Posted October 19, 2012 The only thing I "feel" when swapping to an aluminum driveshaft, is WAY less vibration compared to the stock steel unit. The lighter aluminum is stronger and weighs less, so it causes less harmonic distortion in the driveline. Most folks, when they feel that smoothness, think they gained a lot of power.

WildWillyWalker Posted October 21, 2012 Report Share Posted October 21, 2012 My Fox always had some vibration problems at 60+ then it started to get really bad. I had two different sets of wheels/tires on the car too and the vibration was always there. I bought an FRPP alum d/s and it totally fixed the vibration issue. I bought the correct yoke and swapped it on my Saleen. I noticed no difference in on the Saleen but it was already smooth. Link to comment Share on other sites More sharing options...
OnyxCobra Posted October 21, 2012 Author Report Share Posted October 21, 2012 (edited) LilRoush may have had cars with both types of drive shafts but I don't really think that even matters. I mean you can drive two cars that are the "same" and they can have a different feel so the only way to really tell a difference would be a before and after on the same car. Back to back dyno numbers would be cool as well.Scott I'm not sure a group buy would really be worth it, new they're like $380 but I've found at least five on craigslist between $150-200.

LilRoush Posted October 21, 2012 Report Share Posted October 21, 2012 It wasn't a Roush thing. I had the stock unit on my 2000, and swapped it. Also swapped them on my last two fox bodies. Link to comment Share on other sites More sharing options...
Slykin Posted October 21, 2012 Report Share Posted October 21, 2012 I'd pay good money to get rid of the vibration in my car.. if only I could figure out what it is lol. From the sounds of it, an aluminum DS may be the trick. Link to comment Share on other sites More sharing options...
