Safe amount depends on the engine, do you have forged internals??
Also whats it matter if you can run a 200 shot or not?? My friends 4.0L V-6 Ranger runs a 100 shot and ran quicker then when he had 150 shot.
Start off with a small shot and work your way up. You'll eventually find the optimal N2O shot for your combo. And make sure the check your plugs often, if not after every run, and make adjustments from there.
