Carbon Fiber driveshafts

[Gunburn]

I Have a firend with a Honda Integra that had problem with braking drive shafts (strange for a honda lol) thats up untill he got a set of carbon fiber driveshafts. They are strangely strong....

My question is: does anyone know of a company that sells or makes corbon fiber driveshafts for a KA powerd s13?

(and i did search)

[s14slide]

try looking in the back of an SCC mag, I believe there's a place that is called the driveshaft shop or something of the sort. Here it is, I found this on google.

If you want to find more just google it.

Thx dude

[s14slide]

no prob
if you do get one, hook everone up w/ a review/install

[-E-]

how much will something like that run you?

[s14slide]

look at the first page of the site, anywhere from 4 to 9 hundred, depending on lenght. I seen another site that I got from SCC that made c/f shafts and for a 240 it was like 6 or 7 hundred. But I got that quote about a year and a half ago.

ACPT does 300zx and other c/f driveshafts. Probably send them the specs and they can make em'

how much power can the stock driveshaft handle? how much could a carbon fiber one handle?

Good question which i don't have the anwser to at the moment but i'll look up on it.

lets put it this way the JUN 8 second 700hp Hyperlemon Silvia used the factoru Nissan Driveshaft. cv joints etc. etc.

[Gunburn]

Ya but the JUN 8 second 700hp Hyperlemon Silvia is a s15 want about the s13?

[FRpilot]

iirc, isn't the jun 8 second silvia an s14 zenki?

[knightrider]

wait wait wait, integra breaking drive shafts? um, i dont wanna sound like an asshole but fwd cars dont have driveshafts, they have intermediate shafts and axles

[mixedwell]

hmmm knightrider is right. FWD cars dont use them. the closest thing ive heard a FWD does is break an axle or two. nope no drive shaft in FWD.

fyi: in the 240sx, the drive shaft is a long bar that spins from the engine to the rear wheels. if you look at big rigs or other large trucks you can see some little bar spinning. thats the driveshaft. just incase some FWD people came and read this and didnt know. -GI JOE
holla

mixedwell ;)

[Gunburn]

Sorry i just refer to the "little bars" going from the tranny to the hub "drive shafts" cuz there kinda shafts that drive the wheels so I call them that sorry if i have made anyone made lol

ppl on this site have a problem with getting mad over silly stuff, for example when new ppl join the site and ask simple questions that have been asked before ppl are like "hey use the search bottom you dumbass, see thats what i don't get.....

Most of this is quoted from the Jan. 2003 issue of Super Street that just did a big section about drivetrain mods.
"Upgrading your car's driveshaft can have several benefits. The most direct advantage is weight savings: An aluminum, chromoly, or carbon-fiber driveshaft may weigh laess than half of what a conventional steel driveshaft does. And since an object weighs more when it spins than it does at rest, any weight you can shave off of a part like a driveshaft multiplies when the piece starts to turn. This weight savings becomes eveen more pronounced if you're replacing a two-piece steel shaft with a single aluminum or chromoly shaft.
Another benefit has to do with torsional flex, or the amount the shaft will twist when under a high torque load. Steel doesn't twist much, which means the shock of a hard launch will be transmitted right down the driveshaft to other parts of the drivetrain that could tiwst-or break-under the stress. An aluminum driveshaft has more torsional flex than steel, and carbon fiber has more flex than aluminum, so each will twist and absorb some of that launch shock before sending it rearward.
Now, there are those in the driveshaft business who believe that carbon fiber is prone to brooming as a result of its high torsional flex characteristics, making it unsuitable for use as a driveshaft."

*brooming - the composite comes apart into a bunch of loose carbon strands in an effect called "brooming," since the broken end of the shaft will look like a broom.

I dunno. Sounds a little risky. Super Street does recommend ACPT, but I would talk to them first and make sure what kind of power their driveshafts are proven to handle. I'm also interested in these so if you find out a price, let me know.

any shaft that transmits power (drive) IS a driveshaft so don't worry.

the "do a search" w/out the dumbass part is for your benefit since you'll find much more info from the hundreds of posts on a subject then any new responses. Plus people who have already commented in detail are not usually willing to do it again...

Carbon fiber is an excellent mat'l and lightening up any rotating part would help the engine ramp up faster but like others have said, it's not exactly a proven performer on high torque/long life applications. Also if it were built incorrectly, balancing would be very messy and bonding would be a major issue.

yup its a 95 silvia all stock bodied except fot the fender flares and jun front bumper and FG hood. stripped interior. (couldnt have been an S15 considering it was in the 8s in early 1998 and the S15 didnt appear untill 99 :) )
