The 3-piece OEM design allows for front/back movement to occur. This is one thing needed to consider when going with a rigid 1-piece design. Other considerations include clearance through the pre-existing tunnel on the car. WORKS has been looking into this for a while and will continue to do so. Considering an OEM replacement costs ~$1300, the CF option doesn't seem so pricey. Stay tuned!

BTW install is pretty simple and only involves 8 bolts/nuts and about half an hour.

 

My radio controlled car has a carbon driveshaft going to a VCU at the front diff... it's pretty sweet, about .3 ounces!

 

dynotecheng.com. Saw these guys at the PRI show. They also make CF, Alum, Metal Matrix Composite Alum, and all the normal type driveshafts.

 

Remember guys, that we would only be replacing the rear two shafts in this project... there are a couple companies working on aluminum alternatives in this fashion.

 

any new news?

 

bump for news

 

resurrection.... any news?

 

Another difficulty in using a one piece drive shaft that uses different materials between the joints and the shaft is bonding them together. There have often times been separations of the shaft from the joints due to insufficient bonds where welding is not an option due to the materials used. This is a concern for me that I have seen before that would provoke more research.

I also have to agree with the torque of the motor requiring additional flexibility from the driveshaft. This could be less of a concern with stiffer motor mounts, but will still be required to some extent.

A possible solution could be to maintain the mutiple sections of the shaft for flexibility, but to use lighter and stronger materials to reduce weight. I don't know how feasible this is, but it could provide some other options.

 

Carbon is used in the helicopter I worked on in camp pendleton. I used to work on AH-1W cobras and UH-1N hueys. The response of throttle input was dramatically realized when horsepower is great. Now these shafts where not much thicker than the ones used on our evos and the diameter slightly larger and a little bit longer as well. These shafts were meant to hold 1690 turbo shaft hp x 2 because there were two engines in that bird, and this is in a combat situation where throttle is used pretty heavily and the carbon composite shafts did the trick very very well as apposed to the aluminum shafts they used to use back in nam. I could immagine on an evo. Your throttle response will be amazing compared to an aluminum shaft and much more realized especially for high hp applications.

 

How much??????

 

Digging this out of the grave!!! How many people have a CF driveshaft in their car now? Or has there been some aluminum replacement parts produced?

 

I have one,I also was looking into aluminum shaft but no luck,it was 2700.00 shipped.
I have 0 complaints about it, yes you can definatly feel the difference overall.I'm sure there is a few guys here also that have it could chime in to about it.

 

Do you use your EVO as your DD?

 

No.

 

You won't find too many people with builds like U2SLO using the car as a DD, not saying he couldn't though. Usually when you have a 700whp car it's not your DD you drive around the good gas mileage, work car, or people mover then use your weekend warrior(700whp EVO) on the weekends.
