I have no idea what you're talking about......
That is the result of hitting the spray on a wet system too soon.
dry system well only flow nos into 1 cylinder a wet system well flow in with the gas!
I have no idea where this thought came from. a dry system flows into the intake, then just as the air that enters the motor, the nitrous spreads out pretty much evenly throughout the intake, and into each cylinder, if you had a 125hp dry shot and it went into 1 cylinder that cylinder would quickly find its way to the bottom of your oil pan.
A wet system mixes the fuel in with the nitrous in the intake, then the atomized spray travels through the intake and into the cylinders. Problem with that is that if the air is not traveling fast enough through the intake the fuel will settle (due to it being a liquid) into the lowest part of the intake, and of course the smallest spark will set it off, and boom, no more intake. to solve this problem the engines RPMs must be higher to give it sufficient air speed inside the motor to prevent the fuel from settling, which is why you cannot spray out of the hole.
Dry systems are great because you don't run the risk of fuel puddling in the intake, but the wet system is a bit safer once you are going down the track, as you are not relying on the fuel rail, and injectors, and fuel pressure, and pump (although the pump must still be sufficient in a wet system as well) to keep the motor from running lean and burning your plugs, and/pistons, piston rings up.
