Well my first track outing was yesterday in the old stang and netted me a 12.09 at 117. This was in real bad heat at Mason Dixon. The car is currently on 3.31s and a 28' drag radial. Not to bad I don't think for my first time and a crappy track. But my question is this. Should I put a 100 shot on and keep the gears or venture for 3.90s and keep it NA that much longer? The plan is to go nitrous in the very near future, but really want to run mid 11s NA first. Will 3.90s be to much for a 150 shot on 28s?
