when you line up there will be a person there guiding you. at the top of the tree there are what are called staging lights. two small yellow ones per side. the first is a prestage light, the second is when your actually staged.
once the staged light comes on for both sides the lights will dropin a sequence of three yellow lights then a green.
launch on the third yellow(theres half a sec between lights) by the time the car actually launches the light will be green.
try launching between 3500-4500 rpm. youll have to do a few runs to figure out where it launches best from there. everybodies car and expierience is different. what might be best rpm for launching for one may not be for you.
dont dump the clutch and break the tires loose hard, a good squak is ok. instead try feathering it out to keep the rpms up. this is something else youll have to play with to see what works best for you. clutch should be fine, ive been drag racing on my stock svt clutch with no problems.
one other thing, if you dont have to go through the burnout box try not to, street tires tend to hold moisture in them even after a burnout which can cause them to break loose at the line. instead, go around it and then dry hop them to clean the tread(dryhop=quick burnout on dry tires to clean them)
