look in your manual it should say how much coolant it is, i cant think of it off the top of my head but just grab a couple of those bottles of washer fluid and pour it in there. Technically you need to run a coolant of some sort, its just that you cant use Antifreeze because it's very very slick and takes a long time to clean up which means if any spills on the track, they shut it down for the night. Replace the antifreeze with water or Redline Water Wetter.
A note about driveshaft loops, if you're doing 12s, GET ONE, dont know if everybody saw it at the shootout, there was a 12s car that had its driveshaft blow off, it could have been a very fatal accident.
