I have about 175 miles on my new 2010 GT500. Last night, I did my first burnout with it (which was awesome, by the way). I'm not so concerned about that, but I revved it high enough that the rev limiter must have kicked in because the rpms suddenly cut off and went down to about 4,000. It drove fine afterwards. No bad noises or smells. Did I do any serious damage by revving it that high? My guess is no, that's why the rev limiter is there. I just wanted to see what you all thought. I'm sure I'm not the first one to have experienced this.
