If you compile weights and outer diameters of the parts you are changing (stock and aftermarket) here I can give you a decent estimate of straight line performance change based on weight/inertia sometime this weekend. The model isnt ready for prime time yet otherwise I'd just post that. Also that assumes you are relatively close to stock performance. If that's not the case, let me know and we can find a workaround.
The model won't account for vibration, but it seems the design of the fluidampr is more focused on protection than performance. From what I can tell, the vibration energy is transferred to the silicon and lost as heat for the most part.

Yes the Fluidampr is 5.8lbs but supposedly only 3.8lbs rotational (idk how that works) I saw a dyno comparing vs stock and light weight, and it actually lost about 1-2tq downlow and gained 1-2 top end.
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?
