Some drag racing classes just run heads up- meaning, go as fast as you can, first one to the finish line wins. But this means it is very expensive to compete because you can go as fast as you have the money to spend, up to the technology/physics/rulebook limitations. Other classes have what they call an "index", meaning the cars in your class cannot run quicker than a predetermined ET. In NHRA heritage racing, those index classes are often 7.60, 8.60 and 9.60 seconds for the 1/4 mile. But that still takes $$$ because you have to be able to make your car run close to the index, if not a little faster.
So what's left is what they call bracket racing, which allows you to just run your car as is, and whatever the ET is, is what it is. You will have a class to race in. Your class will have an ET spread - i.e. 10.99 - 12.99 (again 1/4 mile ETs, because that's what's in my neck of the woods.) The difference between ETs of cars is made up via the handicap start.
In bracket racing, once you establish your "dial in" it allows the track to pair you up with other cars in your class that have different times and to know how much of a head start to give the slower car. If the guy in the photo with the 7.55 ET is going against a car with a 8.05 ET dial in, the slower car will get a .50 second head start. The theory is that it will make things evenly matched by the finish line. But the catch is once you've established your dial in, you can not run quicker than that in eliminations. If he ran even a 7.54 ET, he would automatically become disqualified. (aka "breaking out") So it makes it interesting, because if you're the faster car you not only have to run down the slower car and pass it by the finish line, but you have to do it without breaking out. Likewise, the guy with the head start can't freak out because another car is running him down and run quicker than an 8.05, otherwise he loses, even if he made it to the finish line first. It makes qualifying important, because you can't "sandbag" and purposely run your car slower than it can go, figuring that you'll then get paired up with cars you can easily beat. But small things like track temperature and condition at any given time, and air density and so forth sometimes can make it so your car picks up a .100th on a run and you break out.
So that's the long answer and more than you probably wanted to know!

Most of the time when I run my car ,the Skeeter Hawk , I do so at the Test and Tune sessions , and then you don't even need to
worry about a dial in at all.
Just go as hard as you can against whatever is in the other lane . I'd say that about 50% of the time , I get a car that is quicker than
me , but even then sometimes cutting a better light brings a win . It is just for fun , and beating the more conventional cars adds happy time .
BTW , my " dial in" would be about 8.95 currently , so I'd like to know what engine is, in the '55 in the pic .
Mine is a very mild Studebaker , no blower .Bill H

Probably a Buick Gran National V6. I remember seeing launches on TV shows about the Buick Grand National with a little higher wheel lift. I don't think I would like to try that on Lazarus or Meshach when I do finally have them on the road.

I agree with shifter4, taking our cars to the track is fun. A great chance to drive our cars flat out in a safe and controlled environment. I usually take STU COOL to Sacramento Raceway Wednesday night Fun Drags about once a year, just for the fun of it. Last year I made it all the way to the final round before getting beat. Beating faster cars and drivers equipped with drag radials etc really made my day. Try it, you'll like it!Pat Dilling
