Let's Go Drag Racing
Entering a Whoop Ass Wednesday or Mystery Monday street event at Perth Motorplex is where the majority get their first taste of drag racing.

Entry to the event can be done on the day by paying as you go through the Competitors Gate. Your entry fee at these type of events admits the driver and vehicle. After paying your entry fee you will receive an Entry Form, officials at the gate will tell you where scrutineering is taking place. Unless you have work to do like changing wheels, it is advisable to get into the line up for scrutineering as soon as possible.

The Scrutineering Officials will check your vehicle for general safety items and basic protective clothing, there are only a few requirements that are needed to compete at these Whoop Ass Wednesday Street/Grudge meets ... a three point lap sash belt (as minimum), an approved helmet, long sleeves, closed shoes and socks. Bikes need a helmet, leather jacket and long pants as a minimum. Also you will be required to sign an indemnity form at which time you will be given an arm band. If you do not have an arm band you will not be permitted on to racing surface. Also if you have anybody helping you on the start line they must also sign the Indemnity Form to receive an Arm Band to allow access to the start line area. Your 'crew' must leave the start line area as soon as you have done your run.

After going through scrutineering and having a race number allocated, go straight to the staging lanes. The Scrutineering Officials will put a number on the front of your windscreen, that is the lane you line up in each time you want to make a run. Staging lane officials run each lane in turn so everybody gets a fair go and equal chance of going down the track.

When you reach to front of the Staging Lanes you will be instructed as to which lane to run it. By this time you should have your Seat Belt on, Helmet on and done up and window wound up. Once you get to the area under the bridge the Burnout Official will instruct you as to when to start your burnout, if you choose not to do a burnout you can drive around the water and proceed to the Start Line once the burnout Official waves you on. For those doing static burnouts (locking the front brakes and spinning the rears) the only place you can do this is on the concrete Burnout pad. Static burnouts anywhere else damages the surface, which will bring down the wrath of officials!

As you approach the start, there are three sets of photocells in each lane. The first is the PRE STAGE beam, which controls the top light on the Christmas Tree. This does nothing more than let you know you have 200mm (8 inches) to go to the STAGE LIGHT, which is the second light on the tree. The race cannot be started until this light is on. The final beam is the GUARD BEAM, which starts the timers if the stage beam has not been cleared. This usually only applies only to very low cars such as dragsters.

Christmas TreeThe Christmas Tree has a set of independent lights for each lane consisting of 2 small white Globes at the top, the uppermost is the PRE STAGE lights, then 2 small white globes just below it are the STAGE lights. When your vehicle is properly staged both the PRE STAGE (top white globes) and the STAGE (2nd top white globes) lights are on and you're ready to give your full attention to the Christmas Tree.
Next you have 3 AMBER lights, once staged and the Starter activates the 'Tree' each light will flash on in 4/10ths of a second intervals.
Just below the 3rd amber light there is a GREEN (GO) light and below that a RED, (FOUL) light which is activated if you move before the GREEN light comes on.

When the stage light is on, your front tyre is interrupting the stage beam across the track. If that beam is re-opened before the green light comes on ie you leave too soon, the red FOUL light comes on. While this doesn't matter in Qualifying, Grudge or Test runs, however in Elimination Racing it means you are disqualified for jumping the start.

The finish line has a series of two photocells. The first is approx 20 metres (66 feet) before the finish line. The second is the finish line itself. The first and second lights start and stop the Speed Traps to measure your speed across the finish, the second light also stops the Elapsed Time (ET) clocks and therefore provides the Elapsed Time and Terminal Speed for the run.
After crossing the finish line (where the Score Boards are located) you should back off and look for the end of the racing surface (600m past the finish line) while steadily applying the brakes, the return road is off to your left and you should negotiate the turn slowly and safely. If you have a problem and cannot stop, don't try to take the corner at high speed - continue straight ahead into the sand trap which will pull you up safely. If your vehicle breaks down and can't leave the racing surface, pull over to the side and switch your hazard lights on. Please note, while on the return road the speed limit is 30km/h and you must keep to your left as there is two way traffic.

You pick up your time slip from under the Bridge near the Start line. As Drag Racing originated in the USA all timed distances are measured in imperial measurements being feet with the total race distance being a 1/4 of a mile (402 metres). All details of the run are shown - Reaction Time, 60' time, 330' time, 660' (half track) time and speed, 1000' time,1/4 mile time or Elapsed Time (ET) and speed in mph and km/h. Both lanes are shown on the time slip so you can even compare your performance against the other lane.
We will explain about reaction times a little later in the section "WORKING THE LIGHTS"

Types of Racing
Whoop Ass Wednesdays and many other street or grudge events don't actually consist of formal racing eliminations so you can pretty much race whoever you want as many times as you want. These events are about lots of runs and never being eliminated… Just keep racing your mates or anybody until the end of the event.

The next step up the Drag Racing ladder is to enter events where you do some runs to qualify and then true elimination style racing is conducted using different handicap methods depending on just how far up the Drag Racing ladder you choose to go. All Drag Racing activities are sanctioned by the Australian National Drag Racing Association (ANDRA).

When you enter a major Drag Racing event, there are a number of different handicapping systems used. Some are used nationally and others are unique to Perth Motorplex.


Group Three "Dial-your-own" (DYO) Handicaps
Roughly 90% of drag racing uses this system and if you are a newcomer to drag racing this is probably the handicapping that you will use. The Autotrader Fast Fridays is a great place to hone your Drag Racing skills before you take the plunge into a major event.

"Dial-your-own" simply means that you nominate your own handicap time. This gives the slower vehicle of a race a physical head start, which is programmed electronically into our Computerised Timing System. To stop someone nominating a time slower than they can actually run, thus giving an unfair advantage, a "breakout" rule is applied. Put simply, if you nominated 14.00 seconds for your "dial-in" and ran 13.99 or quicker in racing you lose the race. But if your opposition does the same thing the timers award the win automatically to the person "breaking out" by the least amount. This is known as a "double breakout".

"Dial-your-own" (DYO) racing is a very fair form of racing as it doesn't matter how much you spend on your vehicle. Its about consistently running close to you 'Dial In' without 'breaking out' and good reaction times. DYO handicapping provides close, competitive racing for even the first timer. In fact, some competitors have won a trophy at their first attempt.

Group Two National Class Index Handicaps
The second type of handicap racing is Class Index racing, whereby you race on a National Index based on the performance for your class nationally. With this form of racing, to be competitive, one needs to have their car or bike capable of running close to or under the National Index for the class. Eliminators using this format are Competition, Super Stock, Super Comp & Competition Bike. These brackets are run at National Open events at Perth Motorplex.

Group Two Special Brackets at Perth Motorplex using a 'Vehicle Index' Handicaps
Many years ago, Perth Motorplex developed a special bracket call Top Comp which combined all the mechanical supercharged V8's which race under a 'Vehicle Index' handicap system and a three round race format. More details on Top Comp are available from the Perth Motorplex office. Top Comp has generated a large portion of Australia's toughest handicap racers

Group One Heads Up / Pro Start
The highest form of racing conducted at Perth Motorplex is the Pro Brackets where there are no handicaps. It is known as "heads up" racing, where there are no handicaps and both vehicles leave the start line at the same time. These are Top Fuel, Funny Car, Top Alcohol, Pro Stock, Top Bike & Pro Stock Motorcycle. All amber lights come on at once for the start, known as a "Pro Start". This sort of racing takes huge sums of money, great techjnical and driving skills and only a few racers ever get to race at this level.

Eliminations
Competition in drag racing is most commonly referred to as "Eliminations."

In dial-your-own racing, vehicles are handicapped according to a "dial-in" time nominated by yourself. A good rule of thumb is to use your fastest qualifier as a guide, bearing in mind that at night events, the cooler night air will usually improve your times over runs done in the heat of day. Track officials will mark your "dial-in" on the side window of cars whereas bikes will have a "Bracket Marshal" take your "Dial In" and forward it to Race Control.

Now its time for your first round in eliminations… For example, lets say you have dialed-in at 16.10 seconds and your competition dialed-in a time of 15.50. With the handicap system, you have a .60 head start. Before moving into stage, confirm that the handicap is correct by checking the displays on the scoreboards at the finish line. Make sure you know your opponents "dial-in". If you have a question about the handicap, you must advise the starter before you stage. Once you stage that means you have OK'd the handicap and the race result will stand.

Ok, you get in a good run and hold off the your opposition to record your first win. Pick up your time slip under the bridge and return to the staging lane allocated for your bracket.

In round two, you run a bit stronger (things like cooler air can increase your performance) and you record a 16.05 in crossing the finish line first. But this time you have lost the race, because you have run quicker than your 16.10 dial-in. The timers award the win light to your opponent and this is shown on your time slip. Don't forget you can change your 'dial in' between each round so carefully consider all the factors that may affect your performance.

Excepting for some special Perth Motorplex formats, Drag Racing is conducted on a tournament elimination format similar to Tennis. If you win, you continue to the next round. If you lose, you have the choice of relaxing and enjoying the rest of the meet or if time permits you also have the option of doing a few extra runs by lining up in lane 9. There you can do some "Grudge Runs" against others who are also out of the racing. Staging Lane Officials take vehicles out of the Grudge Lane as needed, which is usually towards the final rounds of Eliminations.

Working The Lights
Before diving into an explanation of how to "cut a good light", you must remember three things.

1. Each lane is timed independently of the other, and
2. The timers do not start when the green light comes on!
3. The timers only start when your vehicle moves out of the stage beams

To give an extreme example, if you were to sit on the start line until your opponent crossed the finish line and then leave, you may run a time much closer to your dial-in, but he would easily win the race, simply because he had a much better reaction time - like around 15 seconds better! In real racing this sort of thing happens all the time, except the difference between reaction times is in hundredths of a second.

When you get your time slip after a run, look at your reaction time. Compare it to your opponent. Reaction times work on a simple principle. It measures the time from when the last amber come on to when your front wheel clears the start line beam. A "perfect light" (.000 ) meaning that the vehicle has cleared the stage beam at exactly the same time as the green light came on. This is shown on the time slip as .000. Anything less than this means that you left too early and red lighted (fouled) and this will be shown on your time card as a negative value. Of course any value shown above .000 is of course wasted time sitting at the start line. Most newcomers to Drag Racing leave when the green light comes on. This will give a reaction time of around 1 second. For example, if you pulled a 0.920 reaction time and your competition ran a .260 Reaction Time, you have given away over six tenths of a second start right at the start line. For a more graphic example, with two cars of the same performance running 160 km/h (100mph) in the quarter mile, this .660 wasted at the start represents about 6 car lengths at the finish line!

So, lesson number one in cutting a good light is to forget about the green. Try leaving as soon as you see the last amber light. You'll probably be surprised to find you did not red light. And when you get your time slip, you will be amazed at the difference in your reaction time. After that it is largely up to you and your vehicle. You should try to improve your reaction times until you can run around the .050 second range however anything under .100 of second if pretty good.

If you are puzzled why you can leave before the green light comes on, without triggering the red light… Well, its is to do with reaction times… Firstly, your reaction to a signal, in this case the last amber will be around .170 - .200 of a second. Medical studies have pegged average human reaction times at around this time. Secondly, the reaction time of your vehicle itself - the time it takes from when you stomp on the throttle to when your front tyres move out of the stage beam.
Therefore you can see that it takes almost half the time between the last amber and green to react and stand on the throttle, plus more than this time again, for your vehicle to move forward and clear the start line beam. Naturally, the slower the vehicle, the slower the "vehicle reaction" time is and the earlier you can leave on the lights. This takes practice and varies from vehicle to vehicle....

… and that's it, the basics of how to go drag racing at Perth Motorplex. We hope that by increasing your knowledge of drag racing we can improve your enjoyment of it. Whether you choose to race your mates at Whoop Ass Wednesdays and Mystery Mondays or you plan to race at a higher level, nothing beats the thrill of legal Drag Racing. You can experience that thrill for yourself at Perth Motorplex! … if your good we'll see you at the trophy presentations!
