Drag Strip tips and advice needed.

True confessions, so, the last trip to the strip I totally went unprepared. Not only was plug 7 not plugged in but Plug 8 was not either. I was rerouting things and I guess I got distracted. I finished welding up the O2 sensor and repairing a leak in the pipe connection after the sensor. I also fixed the plug wires and routed them correctly. I now have a tachometer installed as well as a line lock fully functioning. I took it for a short trip to the gas station and OOOH what a difference. I can almost guarantee in the low 12s on Friday, next races. Now I have to learn how to do the line lock, do a burnout and find the best shift points to program into the tach..Question??? If the max hp is at say 5200 (I do not know yet, dyno tune in 2 weeks) where would you set the light to come on the tach? Next week I will do a complete check of all the car before going to the track.car.jpg
