INTRODUCTION TO ¼ MILE DRAG RACING AT TRP
- Upon entering TRP you will sign a waiver and receive a racer tech card, please fill this out completely as it provides track officials with information necessary to conduct the days racing.
- Find a convenient place to park and remove all loose articles from your passenger compartment.
- When it is announced that time trials will begin, get in your car and drive up to staging lanes by north side concession stand where you will see our Tech Inspector.
- Pull up to the Tech Inspector and hand him your previously filled out tech card, at this point he will conduct a safety and technical inspection of the vehicle. Upon completion, he will put a number on your windshield to identify your vehicle to the tower.
- Follow his directions into a numbered staging lane.
- As your staging lane empties and you reach the front of the line, the staging director will direct you into a particular racing lane.
- Now you are in your racing lane waiting for the vehicles ahead of you to leave.
*At this point, advanced drag racers may want to utilize the burnout box – we will skip that considering this being a beginner’s guide.
- After the vehicles in front of you leave, the race starter will instruct you to stage, this is achieved by:
- Slowly moving forward at the race starters direction, your front tire(s) will break a beam of light on the ground
which will illuminate the top light on the tree, the pre-stage light.
- Slowly inching forward you will illuminate the second light, the staged light. STOP.
You are now staged and ready to go!
*Do not worry if you pull too far forward, you will be instructed to pull back and stage again. *This option is not available during competition.
THE DRAG RACE
- When both vehicles are staged, the tree will flash down 3 amber lights to green, Start on GREEN as fast as possible (reaction time).
- Your elapsed time or E.T. will start when your front tire(s) break the staging beams, regardless of your reaction time. Although your reaction time will be recorded on your timing ticket.
- Accelerate through the quarter mile. The end of the ¼ mile will be visibly marked on both sides of track. NOTE: the finish line is NOT the timing display boards.
THE SHUT DOWN
- Since we have the longest shut down area in Ohio (1/2 mile), emergency braking is not necessary – brake in a controlled manner while remaining in your lane being prepared to exit at the end of the track, being aware of your competitors vehicle around you. Right lane vehicle exits right first and left lane vehicle exits second while yielding to the right lane vehicle.
- Drive slowly up the return road observing the posted 21 M.P.H. speed limit.
Pick up your time slip at the “E.T. Shack”, it will display the following information:
- Left and Right lane info.
- Car #:
- 60-ft.: (I1)
- 330-ft.: (I2)
- 1/8 mile (I3)
- 1/8 speed MPH
- 990 (I4)
- ¼ mile E.T.
You can now return to your parking area or staging lanes depending how you are instructed.
The challenge on your next run is to pick an RPM for your engine that will get you the best traction at the start – to decrease your 60-ft. time. Also, concentrate on lowering your reaction time, as it will become important in actual bracket racing. (See Bracket Racing basics below)
BRACKET RACING BASICS
- In Bracket Racing, you choose your dial-in. Say your vehicle runs a consistent 14.27 E.T.
You want to dial-in your vehicle as close to a time that you can run without braking out. Brake outs can result in a loss (going faster than your dial-in time). Let’s dial-in at 14.25 E.T.
- When it comes time to race, the tower will use your dial-in of 14.25 to handicap your car against a competitor who, for example, dials in at 13.00. Therefore, your slower car gets a 1.25-second head start.
- Reaction time is defined how fast your reflexes compare with the starting light. “Reaction” timing starts at the illumination of your green bulb and ends when you break the staging beams.
- If you react slowly to your starting light, yet run right on your dial-in of 14.25, the other driver can beat you by getting there first if he has a quicker reaction time, even if he runs a slightly slower time than his dial-in.
Your dial-in: 14.25
*Say you run: 14.25 e.t. with a reaction time of: .590
Your opponent’s dial-in: 13.00
and your opponent runs : 13.05 e.t. with a reaction time of: .520
Difference: .05 slower .07 quicker
Although your opponent ran .05 slower than his dial in, he wins by .02 second, due to the advantage of his .07 second reaction time.
BEFORE YOU LEAVE TRP, PLEASE:
REMOVE THE NUMBER FROM YOUR WINDSHIELD, AS THE POLICE HAVE BEEN KNOWN TO TICKET FOR THIS.
