I try to do as little to the car while I'm at the track as possible. I have a bracket car, and one that isnt terribly fast (6.30's in the 1/8 ), so it should not require a lot of between round maintenance. When I get to the track, I unload the car, check to make sure nothing is leaking and drive around to warm it up. Once back at the trailer I lower the tire pressure, top off the cell, and put it on the charger. Between rounds, I put it on the charger, top off the cell, and make sure the tires are slightly over where I run them so I can lower them down to the right pressure once in the lanes. I never used remove the hood once racing has started unless something was wrong, but this year I moved the cell up front for the belt drive pump and will need to remove it every pass to top off the cell.
I'll change the oil a couple of times during the year, check lash at the same time, check timing, and put in new plugs. Unless the car suddenly slows down for no apparent reason or something start leaking, I dont fool with it.
