redline is where you risk mechanical failure due to the inherent design characteristics of your specific engine: ie stroke length, rod length, stroke rod ratio, rod material, crank shape, weight, counterbalancing, piston weight, crown height... etc etc.
it is also the point where the engineers have found harmonics would start to affect other things like valve springs, valve bounce etc etc.
forced induction, NOS and all that shit doesnt change the redline ONE IOTA! what is does change is the power output of a given engine design/capacity/VE and lets you reach your redline much faster. thats all.
engines tend to "run out of puff" on the dyno because their cam is deisigned to work within the given rev range of the engine, and outside that rev range, it doesnt work - thats why the engine output drops off approaching/after redline. if you change your cam, you can shift the power curve around. but if you want a cam that works beyond your engines redline, you have ONE HELL of a tasks at your fingertips prepping the rest of the engine to handle it. and some stuff, like stroke/rod ratio is not changed easily, or without big $$
