Now..the whole reason there are backfires is because of improperly designed nitrous kits.
Rich, You are very knowledgeable but on this one I gotta say......Not entirely true.
You can blow the intake off just as easy with a dry shot.
The backfire starts in the combustion chamber where Nitrous and fuel mix with spark.Most commonly it starts with a improper tune or early activation of the system[not enough RPM's].When this happens you can blow your intake off, bend a valve, connecting rod or more with a wet or dry kit.
On a small shot like we are talking about the amount of fuel being injected into the intake is minimal and when it gets combined with 950+ psi of Nitrous pressure at the Fogger Nozzle it gets atomized very well.
Also remember that your at WOT when spraying.So the fuel/nitrous mix is not going to settle and run down the intake.If you have fuel just puddling up in your intake your truck will not run[too rich].
I'm not saying a wet kit is the best way it's just how I like to do it everybody has an opinion.
But in my truck I found it better to add fuel with the kit instead of the injectors.This way I can run my nitrous tune all the time without adding extra fuel with the injectors when it's not needed.
My bottle is always in my truck and ready to go.
On my Cobra I shoot a 75 HP. wet shot through the blower with no problems at all.
