stongest yet lightest driveshaft??? What is everyone's opinion for the strongest yet lightest driveshaft? I am running a LSX 4xx forged motor with 2 stages of direct port nitrous thru a 4L80 to a moser 9". I am making somewhere around 800 to 900 rwhp if I would have to guess. I do leave on a transbrake and this car is mostly a drag car. Any ideas?

Carbon fiber! I got one and its waay lighter than aluminum and is suppose to handle 1000 rwhp easy. They aren't cheap though, if you want to save money go with an iron one. It isn't gonna be light though, but it should handle anything you throw at it.

The PST 3.5" aluminum driveshaft isn't going to be the lightest, but it is a very good compromise between cost, strength and weight. Here is a link to it. http://shop.brutespeed.com/PST-3-1-2...Driveshaft.htm Bob

I haven't heard of anyone breaking one of these. Bob

Minus weight savings I didn't see any gain how ever, I'm not sure if Eric seen any gains with his.
Biggest concern and in all honesty should be a concern with all drive shafts is to be careful when jacking the vehicle up and letting the rear end hang. Most drive shafts this diameter will come into contact with the D/S loop. Letting it do so is not good with any drive shaft no matter what material it is but especially with a carbon fiber one.
Have any questions let me know.

I have been real happy with my PST Carbon fiber drive shaft and Eric just recently put one in his Top Sportman car as well. Nice units for sure and I think I saves around 13 pounds from my Strange C/M unit using the same C/M yoke.

MeentSS02 pretty much hit the nail on the head. I don't recall if the rules state that a carbon fiber shaft does not specifically but it does state you need a drive shaft loop. So most tracks will make you have one no matter what shaft is in the car. I have a carbon fiber shaft and they still always ask me if I have a drive shaft safety loop.

Driveshaft loop required on all cars running
13.99 (*8.59) or quicker and utilizing slicks; except vehicles running
11.49 (*7.35) seconds or slower equipped with street tires

I know I have seen quite a few twisted yokes with the pst aluminum shafts probly only m6 I can think of. I would think it be wise to upgrade to a MW yoke and know its good to go. But I am still running the yoke that came with my pst shaft with no issues. If I had a little extra $$ I would upgrade the yoke. There no such thing as overkill.
