Well guys. This is just not gonna happen with me. Tire MFG's don't want their tires run at speeds above their ratings. Legal problems. Second the Cage guys are concerned about the fact that if it blows a tire and rolls into a ball that their cages might get a bad rap if someone gets hurt. LastlyI have been talking to my wife and have promised her I will no longer try to do speed runs. I hope one of you guys pick up the baton and runs with it. This is the group to do it. I'm out. No supercharger and just back to crawling rocks.
