If I went with my most agressive TT position (Superman), I'd need only 570W for the same speed.
With a fully faired recumbent I'd be at a sustainable 180W.

Aerodynamics matter a lot even at that kind of speed.
And I love to show it to road cyclists by passing them on my rather comfortable and aerodynamic recumbent.
