Try driving around the water first, burnout is not always necessary. You will really just need to experiment. Do a dry hop or test launch in front of water box as you approach the line. My suggestion to you is that you not launch this car over 2500 rpm, with the 3.91 gear it might wanna rip the tires off of it at higher launch rpms, however if it hooks then you can try upping it the next time. Just know that if it hooks you are flirting with disaster on the driveline at high launch rpms. Do you have a driveshaft loop? Hope your tech is leinient. Around here if you have drag radials you must have loop.
