Depends on how 'supah' the speed would be. If it would be higher than light's speed (300.000 km/s) I would be able to travel back in time and change and foresee things before they really happen. I would be the lord of time. SUPAH SPEED FTW.
EDIT: and since I'm incredibly idiot sometimes, I accidentally voted supah strength -.-'
