If you keep it there for a prolonged amount of time you could easily blow an engine, but thats also the engine's "limiter" so it doesn't blow. The needle of the Tach bounces on the redline when you are gunning it...if it goes above redline, then you know there is a problem. If you have a Shark Injector, the needle would go past the stock redline point and begin bouncing at the new programmed redline.
Socal, I believe Sharks enable redline at 7700 rpm or something close to there.
