Ya know, the pavement on most drag strips has alot of grip, more than street. I've heard rumors of the houstan track having soo much grip, alot of racers who use slicks break thier axles. If you've practiced launching on streets and took that knowledge to the strip, then it's PROBABLY a whole differnt world because of the track. I'm not sure about your drag strip, but the one I go to reducts your reaction time of your E.T.
Just build up your tecnique on the strip, not the street
