First drag race eh? Careful, you may become addicted like many of us.
First of all, on non-drag tires, be sure to avoid the water box where people do the burnouts. Drive around it, if this track leaves a gap to do so. Do your best to avoid getting the street tires wet.
Do a small peel-out once you get the car past the water and aimed straight down the track. This is to clear the pebbles and dirt off of the tires. Do not pass the starting line, no matter how "John Force Cool" you think it may look. Passing the tree in a street car on radials is a huge newbie mistake. LOL
Roll up to the starting line slowly, watching the top two yellow bulbs on the tree. Roll up and light the first light. Look over to make sure your opponent is also lit, or if he is waiting on you. This is called courtesy staging. Only jerks roll in early and click off both lights and wait for the other person. The 'nice' way of staging is to make sure both vehicles have the first bulb lit before rolling into the second bulb.
Try various RPMs to leave at. I'd start with holding the throttle around 3000 rpm first, then gradually rolling into the throttle and off of the clutch. Dumping the clutch will result in wheel hop or breakage. If the car bogs, try it next time with more RPM (3,250 perhaps). If the car spins, try less rpm next time, or rolling into the throttle slower.
Shift at redline.
