Either way it seems to “protect” the engine from harmonics better then stock which seems beneficial if you are modded. Stock I think is 5.1lbs?
The DSS driveshaft is 2.75” diameter 12.1lbs, havnt found stock driveshaft specs from looking at it today (forgot to measure it...) it looks 2.75” for 2/3rds then the joint then 3” for 1/3rd of the driveshaft and 24.2lbs?
Assuming a 200 crank hp 170 whp 15% drivetrain loss. What % if any of that is the driveshaft and does lightening it reduce the loss?

The fluidampr has an inner ring suspended in a silicon fluid. It's a fluid damper rather than a semisolid damper. My guess is they don't count that inner disk as rotating weight as a marketing thing, even though the viscous forces would likely cause it to rotate anyway. I haven't looked at it too closely.
Not going to try and guess gains, especially since it's 1:45 am here and waaaaay past my bedtime lol. I'll get you real math-like numbers later.
