Eric, assuming you have stock wheels & tires mounted, what tire pressure were you running at the dragstrip? With traction problems, I would try lowering the pressure down to the low 20's (I wouldn't go below 20psi (cool/warm) on street tires though). That may help you hook it up. You may also need to start doing a burnout prior to launch, just in front of the waterbox (or are you already doing that?). You generally want to stay out of the waterbox with street tires since the tread will pick up some water and carry it up to the starting line.
