Drag Racing, a competition between two cars from a complete stop at a distance of a mile 1 / 4 (1320 feet) depends heavily on the first 60 meters career, or start it. The technique used for the launch is very variable depending on how the car is equipped. The rate of transmission than have been driven wheels, tires, power, suspension and track preparation all play key roles in how to go about getting the best possible launch of the car.
Improvements in the time it takes the car to travel the first 60 meters down the track have important implications for the end of ET (ET estimated). As a general rule, improvements in time from 60 feet, are magnified by 2x in the last hour of the East. For example, a Dodge Viper GTS running a 12.2 @ 120 MPH Mile fourth with a time of 2.0 to 60 feet can make significant improvements to the 1 / 4 mile times by obtaining a better launch. If the Dodge Viper GTS is able to cut 0.2 (two tenths) of a second of time is 60 feet, to cover the first 60 meters in 1.8 seconds, is the final mile ET for quarter would be around 11.8 @ 119 – 121MPH. More examples can be found by searching through thousands of records from 60 feet on the http://www.dragtimes.com drag racing database.
The best release is obtained by obtaining an optimal balance of the application of the most power to the ground with the least amount of wheel spin. If you take too much energy during launch and the tires spin, time will result in 60 feet poor. The same goes for not applying enough energy, causing the car engine to the swamp, and have the car limped to the line slowly.
When the launch of a car with an automatic transmission, a technique called the braking power is used. After appropriate staging the car in the lane of the drag strip, the tightly hold the brake with one foot, while slowly apply the accelerator to sell with the other foot. Car engine RPM (revolutions per minute) should increase slowly to a point in the car or start to move or start spinning the tires. Hold down the brake and accelerator touts just below the point where the car is beginning to move or rotate the tires. When the Christmas tree lights reach the last amber light before the green, lift the brake and slowly push to sell the gas to the bottom. The correct RPM to start each car will be different depending on all the above variables. Home conservative with first launch and keep increasing the RPM which launched the car during races later. If the car begins to spin the wheels after the launch, commissioning RPM in low gear and try again.
By launching a car with a manual transmission to reach a full stop after the vehicle are organized. Press the clutch to the bottom with one foot while pressing the accelerator selling foot, raising the engine RPM at a constant moderate for the first pitch. Levant sell clutch to the point where the car is about to start moving and keep both still preach. When the Christmas tree lights reach the last before the green amber, release the clutch slowly, while applying the throttle quick enough to sell launch the car quickly, but not too much to induce a lot of wheel spin. Start conservative with the first launch and keep increasing the RPM which launched the car in for subsequent careers. If the car starts spinning the tires too much after the launch, lower the RPM up and try again.
For best release and reduce the foot 60 times more, the use of drag slicks or complete radio can be used in more powerful cars have trouble launching RPM in any normal street tires. Drag and complete radio spots usually require a drain cleaning heating and waste tires for optimum performance. A burn is a rapid rotation of the tires of the car while the car stays relatively still.
All wheel drive cars (AWD) are generally the easiest to implement because of the engine power is distributed to four wheels instead of two. rear-wheel drive (RWD) cars are usually pitch better that front wheel drive (FWD), due to the weight transfer to the rear tires during launch, causing an increase in traction. If the car has suspension aftermarket adjustable, you can make specific settings for drag racing to increase the weight transfer to the drive wheels.
preparation Track launch pad also plays a role in how well and how many cars drive can launch. The launch area is prepared compounds usually drive to add the viscosity of the track. A well-prepared trail will definitely help your foot down 60 times and result in a lower / 4 mile times.
During breaks and periods of cooling between drag racing careers, take detailed notes about how you started on the back each Timeslip. These notes can help diagnose problems launching, refine later releases and show improvements in the search for the perfect launch.
