Ballistic 550's a reality

Can someone please clarify what the watt rating of the motors tells me?

The 5.5 turn ballistics 550 motor is rated at 800 watts and a 13.5 ballistics 540 motor is rated at 195 watts. So does that mean:

...that its going to drain the battery 4x quicker when I'm WOT vs ballistics 13.5

...that there 4x the torque throughout the entire power band vs a ballistics 13.5? Insane acceleration?

Can you use this motor in a MMP?

Please enlighten me...I'm stumped...
