At the full-rated (as opposed to down-rated operational) output specification provided, that translates (for used to US units) to:

93,496 HP @ 84 RPM

5,845,726 lb-ft @ 84 RPM

The most mind boggling number for me is the torque figure. Almost six million lb-ft of torque. Power is an important figure when determining how much work you can do, but torque is important when engineering the components that will go in to your drive line. For example, transmissions typically specify a maximum torque input, as well as a maximum rotational speed. Independently, neither can be exceeded, regardless of power input. For example, the transmission in my car is good for about 450 lb ft and 9,000 RPM. I'd love to read over some of the engineering specs for the driveline components attached to this thing.

It's not just that. Part of the reason they are designed to run that slow is because they are directly connected to the prop.
