Stock SVX shaft weighs 35lbs.
I'm getting an aluminum one made soon as I get back to completing my 5 spd swap. $200. I'll let ya know what's what.

Questions, Questions!!! Thanks for the stock SVX driveshaft info. Who are you purchasing the $200 driveshaft from? How much does the aluminum driveshaft weigh? Made from whom? How much does it weigh?

Weight loss is fine and dandy, but its more beneficial when it also lowers the cars center of gravity (IE. removing weight towards the top of the vehicle).
CF driveshaft is a cool idea, but theres better gains to be had elsewhere. Dustin

When it comes to spinning mass, so many people seem so booked on WEIGHT when what really matters is MASS and MOMENT OF INERTIA.
The driveshaft has a very small moment of inertia, so you'd have to rip a hell of a lot of mass out of it to know the difference. Further, by material, the thing has no frictional losses, nor energy transfer losses (like a diff). Unless you are a long way into the car's performance already, you have money that you have no idea what to do with, or you put a mirror under your car at car shows, it's definitely not a way to go.

Well im doing to improve the power to the ground. Not to lose weight (that is a very small bonus) i can take out the rear seats and lose more. Plus the fact it is a rotational item that is a big part to getting the power to the road rather than just losing passenger room.

hmm where would the most benefits be seen in the drive line to improve. I dont know much about what i am talking about it is probably evident Im just going by what people tell me. Im just hoping those people are right. You seem to know what your talking about i withdrew that before statement.

a CF driveaft will NOT get you more power to the ground at all. It will not magically reduce the amount of parasitic loss through your driveline. Your car will simply have the ability to rev slightly quicker. Personally look at an aluminum if you have $$ burning a hole in your pocket. I do not see a TON of weight coming off a 2 piece shaft that the svx has stock.

Ok now odepaj made some good points and didn't have to be a jerk about it. I thought a forum was a place for someone to come and learn from the community not get hassled by some guy pissed off because some one peed in his cheerios this morning.

I know a local drag racer who replaced his stock aluminum driveshaft in his Pontiac Firebird.
It was a 6 speed with about 650 crank horse power, and an absolute HOOT to drive! He replaced the driveshaft with a carbon fibre one ONLY for the reliability. It did not change his ET. With light weight wheels and tires,for example you reduce your weight, rotating weight, helping handeling, braking and acceleration. $1000.00 would buy you light weight wheels, AND lightweight seats,for example.

As far as cleaning up the driveline, gettign more of the motors power down..your better off doing a transmission (manual or a 4.44 auto work well. The autos can get rebuilt valve bodies, ect, for faster shifts) and stiffening up the motor, tansmission, and rear diff mounts
edit: ditto on the wheels and tires. Taking weight off there makes a HUGE diffrence
