Danny you are correct in that the best is not always needed.
In 2003 Greg Nicklas used my SMC GP3300 pack to win the Midwest Winterchamps in Columbus, Ohio in stock truck. They were nothing special. I think the voltage was like 1.148 or so. If you know anything about this race guys like Brian Dunbar, Allen Horn, Jesse Robbers, Matt Francis. It was a great race to watch.
