Just got done watching the show drag race high and the one racer was complaining that the other guy double bulbed him on the tree?..The camera angle didn't show the tree so I can't figure out what he was talking about..It was a pro tree by the way if it matters.

Well I dont know what it is in drag racing, but back in 71 I was at this whore house just outside of Saigon and this woman asks me "hey GI, you want me to double bulb you, we have good time"!

I gotta tell you, when she pulled .......oh, never mind

Double bulbing is putting the prestage and stage lights on before the other racer puts his prestage on.
Most tracks encourage courtesy staging, which means the first racer to put their prestage bulb on waits for the other racer to do the same and then either can go ahead and stage.

Have raced at some tracks where the tree was started very quickly once all the bulbs were on, double bulbing was a way to be ready. Going off the top bulb like I do meant watching the stage and top bulb at the same time if someone double bulbed me.

What Mario said. Lost of tracks enforce courtesy staging and if they do, they will make you back out. Most trees run on a random firing sequence - once the starter arms the tree, it's usually a 1 to 3 second delay before it starts down. Some of the software may be a little weak - seems ours has a tendency to fire faster if one person takes a while to light the 4th bulb. But they only have 10 seconds to light the 4th, so you can't screw around forever.

Thanks guys..I don't think the tracks around here enforce that but then again most of my trips down the 1/4 mile have been on test and tune days.I just figured once the staged light was on you had better be ready to go regardless of what the other guy was doing...On the show I was watching they were basically saying the guy should have been disqualified as if he was cheating.They were all a bunch of whining babies though

Which car won? Ive watched one or two episodes.

Blue Mustang but it was the usual whinerfest

If you didn't build it, it will always be someone else's

The mustang ended up taking the best 3 of 5 but that was mostly due to driver error on the part of the guy driving the Monza..The first race was extremely close...The monza won with a 9.16 to a 9.17 by the mustang...Then for some reason on the next race the monza driver just sat at the line and didn't go..The driver was complaining about something with the tree but I didn't catch it..The next race was the double bulb fiasco with the Monza winning..Tied at two wins each they lined up for the final run and the Monza redlighted handing the win to the mustang...........All in all I was very disappointed with the whole series and don't know why I watched it(nothing much else on I guess)...I couldn't believe all the whining by the two teachers in charge..Also I thought this was going to be about high school students building relatively stock cars and racing them...It turned into high school students helping assemble some very high dollar parts and then having nothing to do with the racing or the final results..

Great info, I had no idea there was such a thing, or that it was not 'courteous' to light both stages before the other guy lit the first one. I'll have to keep that in mind next time I'm at the track... whenever that next time might be (our only track in the area is currently going through a major change of ownership).
