I just had a driveline failure last weekend. I wish I had done a bit of homework and found you first!

[@markwray3905]

Thanks for the explanation.

In our helicopters, we have 9 huge chromoly steel driveshafts (+2 combining engine xmsn shafts) instead of 1 super long driveshaft. What Boeing did to alleviate the bowing from turning 15000rpm (geared down to rotor RPM of course) and 10000shp continuous, is added a balanced flexpack to segmented and braced areas in the driveline. Ive been thinking how useful it would be to add those to big power cars, keeps the driveshafts relatively short and strong, but allows limited movement at very high loads while keeping rigidity at the terminal end of the driveline. I can send yall pics of our driveshaft flexpacks if yall wanted to develop something like that.

Interesting, according to google images it looks pretty much like a guibo style setup(a cylinder-ish shaped chunk of rubber that the driveshaft flange bolts to that's used in place of a U-joint - luxury car thing, "smoother, quieter, blah blah blah"), just with a stack of sheet metal instead of a round(ish) chunk of rubber

Great info to have. Thanks.

[@Swiftwinter]

Really interesting stuff. I watch tons of automotive content but non go into drive shaft details like these guys.
Great content, thanks.

Thanks 👍

HP sells car TQ wins races. A lot of people forget that even people that race.

Question answered-thanks…

[@lianwalton9194]

Thanks for the content-can I correctly suppose that critical speed increases with pipe diameter…?

[@jestablitz3804]

Thanks for upload, very interesting. 2 piece in general heavier ?

As an owner of 1st gen CTSV with approximately 800 rwhp and almost the same torque, we preached to our community about having a custom 2 piece DS made. GForce made one for years, but most the guys wanted a one piece for whatever reason. As you probably already know they came with a two piece. Do y'all have a two piece for the 2004-2007 CTSV?

Carbon Fiber driveshafts are superior though, lighter and less spring than both steel and aluminum.

Im trying to figure out a problem with my 5" x 75" driveshaft i put on my 2nd gen dodge 4x4 5 speed with a 12v cummins. At around 35mph under load i get a loud noise i can only describe as a concrete saw sound. Definitely an aluminum sound. I have zero vibration, in fact, my truck has never been smoother. My angles are nearly perfect. Is this just the drivetrain noise being amplified through the giant hollow tube, or is it something else? How can i eliminate it? because i hate it lol. I feel like trying to add a strip of sound deadening to it to see if it helps.

Thank You ! Good Tech.
