yes, most reports are a 5-10 less hp loss. I don't think any cars come from the factory with cf, but they are big for aftermarket muscle cars for drag racing.

 

a couple of good sites for info:

I'm kind of surprised CF shafts never caught on with the aftermarket crowd. Drivedrain loss can be a ***** and a lighter shaft would seem like a good solution. I'm not sure how much one would cost, likely more on the high side, but you would think there would be a market.

 

one of the articles I read said about 3x that of aluminum, so about $900-1000.

 

when some one can spend that much money on engine parts and over come the hp loss or even have more hp than with a cf driveshaft.

 

CF driveshafts are good, strong and lightweight. Impressive Nissan would do this from the factory.

Although, I honestly don't know what to think about CF driveshafts in general. I've seen a turbo AWD DSM have its CF driveshaft shatter like glass on a dragstrip.

Must've gotten the bad one of the bunch? Or just maybe because he's putting down too much AWHP. *shrug*
