Time slip translation
Once you are on the return road after your turn down the quarter you will receive your time slip.
Lets have a quick look at it now.

ATMOSPHERE
The first group of figures refer to the current atmospheric conditions at the track,
Air temperature, air pressure in hectopascals, humidity in the air in a percentage and the surface temperature.
You might be wondering why you might need to know all of this, well a lot of professional racers tune there cars to a very high standard and with atmospheric info like this it allows adjustments to be made to the cars tune. It also lets the cars driver to more accurately estimate the cars ET (Elapsed Time), this is very important and will become more apparent in bracket racing, we will cover this soon.
Next on the time slip are the lanes, Left and Right. Your cars ¼ mile info will be under the respective lane on the slip.
Below your lane are your cars details in the form of your cars number or ANDRA number. You get your car number when you register at the track, it is a one off number and will be different next time you go to that track. If you have an ANDRA (Australian National Drag Racing Association) number you will use that for all races you go in.
Now comes the important numbers
Dial
Dial, this is used during bracket racing. Bracket racing is where you choose a time that you think your car will go no quicker than. The car next to you does the same thing. For example if you dial in 12.250 seconds and the car next to you dials in 12.000 then that car will receive the green light .250 of a second after your do. That’s right both cars launch at different times that means you have to be careful not to launch on the wrong light. If both cars dial in’s are accurate then theoretically they should both cross the finish line at the same time. If either car goes faster the their dial in then that car is disqualified. This is where RT (Reaction Time) becomes very important. Let look at RT’s now.

Reaction Time RT
Your reaction time is the time between your green light and the time your car crosses the start line and activates the timer. As mentioned in Drag racing for first timers you can get a better RT by launching on the last orange light instead of the green. The average RT for every day, race your mates drag racers, is any where from .001 to .350 of a second. With practice you can get better RT’s and aim for a perfect RT of 0.000.
A point to note. You can have a RT of 2 minutes and still run a fast time. Remember the timer does not start until you trip it as you leave the start line.

60,330, 660 Foot times
Next on the time slip come the 60, 330 and 660 foot times. These are all the elapsed times it takes for your car to travel these distances. The 60 footer as it’s know is a very good indicator of you and your cars ability to launch and your cars performance ability. Basically the fast you can go 60 feet the better your car accelerates. In the slip shown the car in the left lane has a 60 footer of 2.247 seconds. This car was stock and after an exhaust, new diff ratio and a full tune was doing 1.880 60 footers. High performance street driven drag cars do 60 foot times as low as 1.550. remember that 60 foot times are a combination of launch technique and a car’s acceleration ability.
Now comes your speed in MPH at the 660 foot mark, then your time for the 1000 foot mark on the track.
Elapsed time ET
Now comes the number that you go straight for when you get your time slip back, your cars ET (elapsed time) The time from when your cars wheels trigger the timer at the start line until when your cars wheels cross the finish line. After your ET, your cars speed in MPH is shown. This figure is gained by measuring how long it takes your car to travel the last 66 feet of the track. Your speed is also shown in KMH also.
The last thing on yours slip is who came first and by how many seconds or fractions of a second.
