There are many ways to get a 150 shot, all with varying degrees of stress on a motor and drivetrain. I'd say that at a given HP level, a fogger is one of the easier methods on the drivetrain, as each cylinder gets its own tuneable fuel for each cylinder, which the nitrous helps atomize. (Does it actually freeze the fuel as well since nitrous is like -125*F as it changes phase? I just thought about that lol.)
Mixed-delivery plates are the next step up in violence, because you are at the mercy of the distribution pattern of the manifold, plus the fact that the nitrous (gas) will not have the same distribution as the fuel (liquid) and therefore have minor inconsistencies in the tune for each cylinder.
Hardest of all would be the dry kit with a reference line to the FPR since you have now completely separated the delivery methods... fuel comes in direct while the nitrous snakes its way around the intake tract and thru the manifold and heads. If you are lean on the fuel with a dry kit you will find out in a big hurry!
All that being said, as long as you're activating above 3500RPM or so it's less likely to make pretzels out of drivetrain parts, or eject shrapnel at the clowns standing close to the car on the side of the starting line
