Hi!Great to hear we've got another Y-Block ready to go down the track. If your waiting to actually see the green light, you're late. Depending on how you stage and the diameter of your front tire you could be adding over a second plus of ET to your timeslip, just in reaction time at the line.
I like to stage shallow, where the pre-stage and staged bulbs are both lit. Some tracks don't allow double bulbing but if they do this technique will generally increase your trap speed. It can also draw your competition into a situation where they red light and lose the race.
It also allows you to roll out and actually start your car before the green light comes on. Where it gets tricky is you have to know how your car reacts, your reaction time and the diameter of your front tire to know the actual roll-out before you break the beam and red light yourself.
It takes a good deal of practice and every time you change one variable, like the tune up on the car or the tires, it changes your launch. Work on that and you'll be surprised how many races you can win.
