Here's the specs on a Warn M8000
http://www.warn.com/truck/winches/src/M8000.shtmlLine Pull Lbs.(Kgs.) Line Speed FT./min Motor Current
0 42 80 amps
2000 16 200 amps
4000 11.9 285 amps
6000 9.79 350 amps
8000 8.01 435 amps
So a fully loaded 8000lb Warn winch will draw 435amps. I don't see a York putting too much strain on that 4.5hp motor so it can't be but 80-200amps. Yeah, it will suck down your battery pretty quick but since it puts out a crapton of air, it won't take long to air up your tires.
