Please add to that the trap speed info. Too many times, people think their trap speed is how fast they were going at the end of the 1320' but trap speed is actually an average speed taken from 2 points.... yada yada.

Do you have the distance between the 2 points and at what points that is? I don't know what it is.

SPEED TRAPS AND ELAPSED-TIME CLOCK BEAMS:
The first of these infrared beam sender/receiver triggers is located 66 feet before the finish line and is used to start the individual lane top speed clocks. A second beam, located at the finish line, shuts off both the individual lane elapsed-time and top speed clocks, and triggers the win indicator. The 66-foot speed trap computes top speed.

http://www.nhra.com/basics/basics.html

Two Separate performances are monitored for each run: elapsed time and speed. Upon leaving the staging beams, each vehicle activates an elapsed-time clock, which is stopped when that vehicle reaches the finish line. The start-to-finish clocking is the vehicle's elapsed time (e.t.), which serves to measure performance. Speed is measured in a 66-foot "speed trap" that ends at the finish line. Each lane is timed independently.
So from what this says, it takes the measure once at 1254' and again at 1320' and averages the 2 to get you your top speed.

YES. Courtesy staging is a MUST. I absolutely cannot stand when I come out of the burnout box and the guy the next lane over is already staged.

I think I've only done this once. It was at a private test and tune when we rented the track. I did it to a friend who didn't even notice.

Will never do it during a race. Ever.

Speedo's probably off by a few, as well, which would have inflated the number even more. And then if you change tire sizes...

I know the speedo is probably off to. However, I couldnt justify it in my head when I crossed the line and it says 118-120 when on the slip it says 109-110. stock tire size. Thanks again.

I was watching a show on drag racing. What does sandbagging mean?

Kind of like teabagging, but with sandbags.
