The Compulink AUTO START System once armed to :ON

[Bobby Fazio]

For sportsman, it is 10 seconds to timeout and it starts when 3 bulbs are lit.

Hiya Bobby and TY.

That answers questions 1 & 3, but not when it was instituted by NHRA, which is question 2. And thanks for the correction on seconds to timeout, different than the pros use.

I appreciate your input Mr. Fazio!

The number of veteran racers who still don’t know this is baffling.

10 seconds is for bracket/handicap tree, 7 seconds is pro tree BUT when racing at a new track to you, confirm with track management before your 1st hit.

I'd be grateful if someone could explain to me how people can get timed out after 1 or 2 seconds if someone turns on a stage bulb (lighting 3 bulbs total) and turns it back off. Something about it starts the autostart and doesn't reset after the stage bulb is knocked back off and both drivers are pre-staged again. Seems to me like it would reset when it sees 2 bulbs again but apparently it doesn't. That's how dragster drivers are able to turn the wheel and dick people who won't stage straight away.

Once 3 bulbs are lite, there’s no reset if you back out or turn your front wheels.

i was timed out in atlanta div 2… my competition turned on his stage light and i went in next and it blinked twice and i went in again and put the stage light on and i was timed out… my dad went to the official and asked him what happen and he said the time started as soon as i blinked the stage light the first time… 7 secs…
i was red lighted….

Obviously, some things have changed (definitely was 7 at the beginning) but Jeff explained it to me that 3 bulbs was the trigger - period. It would not reset if someone backed out or if there was flicker after that. Once the requirements were met it would run to completion. I don't know if that was a design choice or just a function of the components they used.

It was always 10 seconds for bracket/class racing/ handicap/sportsman tree.

So far, according to my research everyone is correct, and I thank everyone so far for the input, and really would like to see more of it. There are 3 different system coded setups.

1 for Pro's, 1 for Sportsman, and 1 for all the rest and it isn't a straight up set always the same guess able tree start or activation timing system. It is what makes tge system fair, and keeps drivers from guessing at the tree. It was designed to emulate the great Buster Couch and his variability in starting the tree, and attempting to keep the drivers from playing games. And I love it personally, no deep staging, starter has 1 control, he is no longer in the game beyond checking the track, making sure the track is clear and safe for the competitors (both those who just left, and those who are about to, and track personnel), then he (the starter), has the only choice, arm the tree, by flipping the Compulink Auto Start switch to :ON !! (that will appear at the bottom of our time slips.

At that point, everything is now in the hands of the 2 drivers competing in the race, and the variable timing system with few base rules ...Both must prestage to start the base and variable timers..
The system base start , Don't go deep, don't back out (roll or intentionally), it does not start the initial timer by a simple bulb flicker, both must be securely pre-Staged, then the third bulb, triggered on by either competitor lighting fully, starts the activation of a variable but set base timer (here is where the 3 differing types come in a quicker time period for Pros, a little more time for Sportsman, and even more time for all the rest, that just makes the other competitor not yet staged up do so or foul out due to them not doing so, and that time is set, then (many other things as far as rules that can allow both competitors to foul out, again, going deep, rolling back, leaving early, etc).

Either or both go deep they foul. Both staged, the tree is now fully armed for a variable, but fair start, that stops both from attempting to guess the light so to speak, as it may come down immediately, or in a few seconds. you don't know, the computer (once armed by the starter and that 3rd bulb is turned on...is in full control).

3 different things are going on 1. Starter in control of safety, then all clear switch flipped, (starter still in control
of emergency stop button only. But he has given his Go! Signal. 2. System is armed, now Competitors are both in charge, as both must prestage fully to start the base system timing (keeping the burn down staging games to a minimum), starter is still in control of the competitors at all times, but no longer really in control of tree start timing except that e-stop button (but he can concentrate on the competitors and the safety of a clear track), then at least 1 if the competitors or both, must move in to the fully staged position to activate the secondary timer and tree is activated,, if the other driver fails to stage within the given time they foul out triggering a red, but that is done by the computer that is in control as the starters go signal was done long ago.

If both drivers do their 1-2, 1-2 job, the tree is seamless, and as fair a start as you will ever expect or experience.

1. Both drivers know what to expect. We know the basic rules, forward motion always. It takes 2, no starter involved except stage commands, starter is just there for safety, not a part of the game. And best of all, the competitors have little chance to actually play games, and no time limits to pre-stage, but once the 3rd bulb is lit, better get in timely! And lastly, guessing is risky.

The when and why, according to my research the why...The 2008 Pro season saw a lot of Guessin starts at the tree, the system was a bit too reliable and some Pro's were watching the tree (a lot more than just pro drivers were), and it was just flat out too predictable and too easy to guess when those .4 tenths yellows would flash, Pro drivers in the top fuel ranks were leaving before the yellows even activated, and it was evident.

It wasn't even "NHRA" as a body that requested that something must be done. It was the NHRA Driver's Committee Input, and The masterminds at Compulink went to work coding after the 2008 season was over, and it Debuted in the first 3 National Events of the 2009 NHRA season. (And proved it's worth immediately as the first and second races of the season saw a few Red Lights from Top Fuel Guessers, and it surprised more than a few drivers, nobody was guessing by Gainsville, they were now leaving again on yellow).

It has evolved to a very fair, and reliable starting system.

Like I said earlier, as a returning driver, I love it, it is clean, it is reliable, and best of all it is fair in my opinion, no games, straight forward, a great evolution in the game.

You. Me, the starter for safety (but out of the game early, still in control of us), and the variable computer that is fair, we know what the fouls are in advance and best of all...We activate the tree by our actions. And most times it is seamless, until it isn't.

You, me, and the tree. Like a drag race should be, a fair start! (If we start playing guessing games, somebody is going home early). Best of all, our tyranny guys are replacing a lot fewer bands and clutches. What a side benefit!
