I have hit the limiter a few times, and it feels horrible. Afterwards I have this nagging feeling that I broke something. My is set relatively low, 6500, and I hear I can bring it to 6700 no problem. And, if you go to the track, sometimes you see 4 bangers hitting the limiter at the line before launch. And I mean, not an accidental one time tap, they are just railing on it. Does it hurt the engine to hit the limiter?
