this is a warning for honda owners and mecanics: the folowing pictures of can be very disturbing

Check this beauty out. Apparently the guy was showing off for a friend, and was at about 7k RPM in 5th when he decided to downshift to 4th (why, neither his friend nor I could tell you).

His friend mentioned that he "had never seen a tach swing that far past the redline", and estimated it to be somewhere in excess of 13,000 RPM before they heard a loud explosion and smoke came pouring out of the hood.
