I'm using a "Hamstick" monoband 60m whip ant on 60m mobile. Any idea of how much power to the antenna to get 30w-50w ERP? In other words, just how ineffecient is a 7' whip as compared to a half wave dipole on 60m?

Your Hamstick is MAYBE 5% efficient.  So you can probably run a 500 watt amp and still not meet the 50W ERP max limit.  Of course, the Hamstick won't take 500 watts.

The 'stick' you're using as one half of your antenna with the car as the other half may do much better or much worse than a 14 foot total lentgh dipole on 60 meters.  

The absolute best you can hope for on 80 meters with such an antenna is 1 to 2 percent efficiency.  60 meters would be a little bit better.
