If you need to steer in a hurry, a power steer car with no operating pump with be hard to steer. That could be bad..
I doubt the PS pump will use much power when going in a straight line to affect your ETs anyway.
As far as hurting the pump or box (if that's what you're worried about), don't worry, you won't.
