Message	by "failed?" In another car I had several plug porcelains fail, but that was because I accidentally ran 50 degrees of timing on nitrous, and melted the plugs. Was the plug defective, or did you burn it up from a lean mixture? If it was lean, then then the problem isn't the plug, etc, etc. I think you see where I'm going. I wouldn't feel bad about the times, because: - 11.40s is awfully quick for a _real_ street car - There is a very weak link between rwhp dyno numbers and 1/4 mile times
