Quick run down. 3000 lb/wd. 315 drag radials at 16 psi. Ladder bar car. Ladders in bottom hole. QA1 single adjust one click left 2 clicks right. Anti roll bar. 80/20 front shock setting. Launch at 4 psi, 3500 rpm on trans brake.. Wondering if there is anything to try to get traction on a questionable surface. All asphalt it was sprayed with VHT. its a small 1/8th mile track.

Your bottom bar should be level to the ground at race weight for a starting point. I would also set the front shocks as loose as they go for weight transfer. Hopfully this helps you out. Tom
 
What's your gear ratio, cam and converter specs?
She takes off nice and straight.
 
I'm not sure how much adjustment is in your front bracket, but from the video, i personally would try one hole up. It did launch nice, but the hazing of the tires along with the smoothness of that launch, makes me think you can hit those big tires a little harder.
 
after watching the vid and stopping it right at launch I have to agree with tom and rick. try one hole up, then two. you aren't getting any raise in the back at all which means it's not hitting the tire hard enough.
I would still reset the front to 90/10 to get the weight up faster.
 
all the x275 guys run about 18psi in there tires and hit the radial hard. most tracks that have radial races prep just for that tire. do the tires show signs of wrinkling? do you have a MSD power grid or 7531 box that you can make you a timing curve with?
