Well my 2 cents is, it depends on what kind of racing you are doing, ie, just racing for the fun of it, racing dial-in, or bracket , etc, BUT if you are racing for a series points/ championships, like we do. We have won 3 NHRA Heritage championships, so we don't plan on doing major work on the car, but we are prepared for it. You can't win events or championships if you don't make rounds.
So what we bring,[chasing points] is two 10x15 easy-ups [ Calif Sun] that we install lights under the easy-ups for racing, working, eating at night, 3 outside trailer lights too, 4' fan to blow alky fumes away from crew and driver during warm-ups, four 3" ramps to get the Pro-Jacks under the car that raises the dragster to waist level [ our crew ages range from 54 to 74], of course generator , air compressor to operate that stuff, yes a small stool to get in & out of trailer and the driver to get in the race car for warm-ups [ it's a rule, no car can be running w/o a license driver] , gas jug for generator [ we seem to refill it everyday on the way back to the track from the hotel] a jug for water to fill the water jackets, five 5 gal jugs of alky in case we get 3 qualifying and 3 elim runs, tools to do between runs work, valve lash checking, valve spring checking and RR to replace springs, timing light, leak down tool [ for engine and barrel valve], torque wrench [ small & big], small air tank to take to staging lanes for last minute changes, air gauge of course, infra-red heat gun to check engine heat for warm-ups, and heat just before staging, track and tire temps, and engine and tire temp after a run, filtered funnel for fuel, drain pan to drain puke tank after every run, tune-up stuff, jets, shims, even nozzles, enough spark plugs to check for heat and jetting changes [ I change at least one new plug every run to see what's going inside the combustion camber & I will change all the plugs on an important race], 2 step chips, shift light chips, laptop computer to down load RacePak info to make tune-up and race car changes, spare, but different slicks on wheels, spare but different 3'rd member , 3 different converters [ we might just change one, but since I have them, I bring them in case a fellow JF racer needs them], of course oil, for motor, trans rear-end, pit scooter and generator, head and intake gaskets, spare rocker arms, push rods, spare mag and cap rotor, wires, spare pilot chute, burn-out screen, primer bottle, front end ballast, engine blanket to cover motor to keep heat in the motor between the pit and start-up lane [ I try to get the all iron motor up to 180° to 200° while staging] flash lites, and of course 4 tables, 8 chairs, 3 coolers, BBQ, lunch , battery charger, 24 volt remote battery for starting [ it weighs 10 lbs] and enough tools to do all this work.
Banners and catalogs for the JrFuel Dragster Association sponsors [ Mallory Print, Hayden Wheels, A-1 Performance, S & W Race Cars, ERC Race fuel, Motul oil], and JFDA T Shirts we sell at the tracks.
That's all I can remember now.
