What does et mean in racing?

  • It doesn’t, E.T. is Elapsed Time, the time when you leave the starting line until you hit the finish line. You could sit at the line for a minute without leaving the staging lights and still run the exact same ET as if you left on a perfect light.

Upon leaving the starting line, each contestant activates a timer that is, in turn, stopped when the same vehicle reaches the finish line. The start-to-finish clocking is the vehicle's e.t. (elapsed time), which serves to measure performance and often serves to determine handicaps during competition.

A real drag racer knows that ET is what tells how fast the car is, RT is really important when winning a race, especailly bracket racing, 60ft tells traction, and MPH tells how fast the car should be running. IOW: ET is what really matters, while the other numbers, including dyno numbers are tuning specs.

Technically speaking, reaction time doesn’t affect ET. ET is the time it takes your bike to move from the starting line to the finish line. Reaction is the time that it takes from green light until your bike leaves the starting line. Adding those 2 numbers is commonly known as your package for that run.

While consistent practice is a huge contributor to measurable improvement and sustainable success, it’s one piece of a larger puzzle. Racers like to say that seat time is crucial to becoming a great driver. I’d qualify that statement to read: “Seat time is a crucial component to becoming a great driver.” If a driver doesn’t have any idea what they’re trying to accomplish on the track and/or they believe that there is nothing left to learn from competition, he/she will not benefit ...

Since organized drag racing grew from street racing, if you challenged someone to race from one intersection to the next, you are racing on the "main drag", thus "Drag Racing".

So many times I see drag racers scratching their heads as they review their slips, wondering why they didn't win when they crossed the line first, their Elapsed Time (ET) was much closer to their stated Dial-in than their opponent's, and they didn't break out. They know that Reaction Time (RT) has something to do with it, but aren't sure how.

CAR NUMBER Most cars are assigned numbers at official races and must be visible on both sides of the car. CLASS Marked if running in an official race. Not used for test and tune sessions. DIAL-IN This is the elapsed time you think your car will run. REACTION TIME (RT) This tells you how quickly you reacted to the green light on the Christmas Tree. In this case, it is set as a .500 second or sportsman Tree.

A drag race is a competition between two vehicles racing side by side in a straight line for a distance of a quarter-mile (sometimes it’s an eighth-mile), held on a monitored drag strip/racetrack – and in most scenarios, whoever makes it to the finish line first wins. At a drag racing event, there are a series of individual matchups between ...

Calculate 60' 1/8 & 1/4 Mile ETs & Trap Speed From Horsepower. This calculator estimates your 60 foot, eighth and quarter mile elapsed times and trap speed when given the weight of the car and flywheel or wheel horsepower. An 11% driveline loss is assumed for Wheel HP. See my Free Android Drag Racing Calculator App in the Google Play Store.

Drag racing, a contest between two cars beginning from a complete stop over a distance of a 1/4 mile (1320 feet) depends heavily on first 60 feet of the race, or the launch. The technique used for launching varies greatly depending on the how the car is equipped.
