Ive seen several people doing the blower and N2o combo with good results.Ive been looking at doing it myself for the cooler effect. The thing is to drop back on the boost a little and you end up making more power and not tearing up the engine. I know that sounds like it does'nt make sense but it works. The N2o just about doubles its power when added under boost so by running too much boost you are pushing the motor harder and creating heat, which undermines (a little bit) the N2o.
I know most people with blowers always end up with a blower with the highest possible psi they can get out of a blower, so it probably is'nt running as efficiently. So by dropping back on psi and adding a 50 shot will make more power. But this all depends on you having the right setup. You need the right size injectors, fuel system, ignition, computer, etc. If not, you will blow something. Mostly your wallet.
