Electronic Time Slips

[Jeff Stout]

Just posted on another thread. No timing equipment needed. Just compare your DRAGY unit with their DRAGY unit and determine winner.

Dragy uses high speed GPS satellites to accurately measure your vehicles performance within 1/100th of a second, producing identical results to the much more expensive and cumbersome VBOX system, in a less expensive and easier to use package. The Dragy software automatically charts slope on all timeslips which you can then post to forums or social media, share with friends, or even upload to the Dragy leader board. The Dragy box is extremely compact at 1" x 3" (25.4mm x 76.2mm) and can be set on the dash when testing and stored in the glove box or center console when not in use.

In addition there are many advanced features under development including superimposing performance data over your mobile camera, virtual races with friends, an internal feed for photos and performance discussion, and more to come. Runs are saved in both metric and SAE formats, allowing comparisons of 100-200kmh and all metric equivalents. You can also define your own performance windows for measuring both trap speeds and/or elapsed times, time to brake performance such as 100-0, and much more.

The system can be run simultaneously with JB4 Mobile and other bluetooth apps. Requires the Dragy app which is available free of charge for both iOS and Android.

Features:
Measure acceleration (0-100kmh, 100-200kmh, 1/4 mile and more)
Measuring braking time (100-0kmh, 200-0kmh and much more)
Lap Time (available soon)
G-force measurement
Highscore list sorted by manufacturer
Dragy
Video Drag and Drop
Profile (garage, profile picture and much more)


Box contents:
Dragy Performance Box Lap and Accelerometer
USB charging cable
2x metal plates and 3M adhesive strip
Manual

Just getting the time down to .01 (1/100) is not close enough to determine a winner in a race.
I have won and lost races down to the .0001 before and most time slips does not go that far into the .0001 numbers unless those are needed to determine the race.

I believe it shows 4 digits over. I'm just staing it is .02 difference from track time slip. We feel because of no rollout on dragy. You move it starts timing. That would be equal 2 both cars being .02 off actual.

[Stan Weiss]

No. The difference between draggy and your time slip will vary even in the same car between shallow and deep staging. Since it sounds like draggy starts the timing and measured distance from first movement.

The 4 digits is only on the who crossed first and 3 digits on your and their ET.
What you posted looked to me to be for your ET only to the 2nd digit and not down to the 3rd digit.
Without the reaction time included in it how would you ever decide who won?
When I started racing in the 60's the tech person at the finish line picked the winner and hand wrote the ET cards declaring the winner and pulled the ET and MPH from a readout to put on the card. I believe the system used then was called a Crondex or something like that. I remember it doing a lot of clicking when I was near it.
I still have the winning cards for all my class win trophy's long before they were Wally's.
I really am getting old.

Your correct. I looked at my dragy log and only 2 digits to the right of decimal. I guess the point i was making is the future is around the corner for no time slip booth. Or clocks needed. Never needed to know reaction time to determine winner. Who crosses first and dont break out or least amount to break out of the 2 would decide

[Larry Hill]

Ron for those of us with app-less flip phones each reaction time will be displayed on the scoreboard on the journey to the finish line. Fair is fair.

Anybody want to buy a Gameboy....cheep?

And you don't think someone will figure out how to cheat during the actual run, in live time, while racing down the track? Does this not concern anyone? Absolutely NOT a fan of anything like this!

With no reaction time? I can see the fights in the pits now. lol

The Tulsa dragway app was easy and showed everything but names only car number. Since it is an app I would think that there would be no range so people could follow the race 1000 miles away.

At my race tracks back in the 70's... before the booth on the return road.. we just dropped a hand written time card (business card size with timing sponsor on it) down a PVC tube into a basket at the base of the tower.
Might have to go back to the future...at some time. BTW Gary years ago there were no reaction times and we didn't have fights. I've always though things would be better without reaction times.. You would have to really work to set up your delay box...
