You are wrong there buddy. He could potentially loose his life if he looses control and hits a tree or a light post. And what if he hits someone walking down the street. Keep your racing at the track.I think you got that backwards, the Trialblazers weigh a little more then the Durango so if anything the Durango should take it off the start, especially since the 5.2 has more down low grunt then the I6 does. After that the (I'm guessing) better areo of the Trailblazer and the fact that it has 40 more hp will take over. Just race him and find out! You got nothing to lose, except maybe a ticket if your not smart about where you race.
