I just had my first day on the track at california speedway today at the nasa event. I had a great time but that all turned bad real quick. I have a 97 cobra s/c and the second time out the pully that is added o n with the kenne bell kit snapped and my belt shreadded but luckly I did not reck the car. Needless to say I'm going to get to participate on sunday, bummer. I think I'm going to get rid of my kenne bell s/c and all the goodies I have for it and invest in the suspension tires and brakes since the supercharger isnt helping me learn anthing exept how to compensate for screwing up the the turns lol. Anybody in the market for a supercharger send me a pm. Anyway it was a great experience and suggest hpde's for anyone that wants to learn to drive better and see where the sphinker limiter tells them to slow down.
