Off the line acceleration is everything in the 1/4. Like my 1/8th I hit 89MPH but the 1/4 is 109. That is only 20MPH in the second half of the run but almost 90MPH in the first half. My 60' sux too so don't feel too bad. Most of the NA trucks in the 12's cut a 1.60ish 60' but only trap around 100MPH so that shows you how important launch is. What your times tell me is your truck has a good amount of HP but is traction limited. BTW good run!
