Exclamation Question.... What's the diffrence between Wet NOS and Dry NOS?

I just have a question someone asked me today... what's the diffrence between Wet NOS and Dry NOS ? I mean i would like to know this myself.... I've always been wondering the pros and cons to it... Does it take 2 tanks for wet or what ?

Or someone could take 2 minutes and answer his question.

A dry setup has the N20 spraying directly into the intake. A wet setup sprays fuel and N20 through the injectors, and is a safer method.

More times than not when some one is using "NOS" (dang I hate that word with a passion now) they are using a dry system. I think when you get above a 75 shot you should run a wet system.

On a rotary, unless you have an EMS you should always go with wet, for reliablity reasons. Unless you really know what you're doing, and since you asked you don't. Next time please search......i've answered this Question several times, there's tons of useful info out there for you.

Alright: picture nos as liquid air. It allows for more power by splitting apart into oxygen atoms (and two nitrgen atoms which act as a buffer to prevent violent explosions).

Since we are adding more air to the engine, we must also add more fuel to prevent detonation (which means a popped motor). There are two ways of doing this: Wet or Dry.

A Dry system jets in a set amount of nitrous and then uses the stock fuel injectors to add the extra fuel. They either does this by bumping up the fuel pressure, or by tricking the ECU into thinking the engine is receiving more air.

A wet system adds nitrous oxide and fuel in a fog, mixed together. Fuel is taken from the fuel rail.

Each system has their own pros and cons, but, as stickgoat said, wet is NOT necessarily a safer system.

A wet system, since it is spraying fuel, is much more prone to nitrous back fire. Incorrect tuning, use below 3000 rpm, or incorrect jetting can cause the wet spray to ignite back through the intake mainfold. This is VERY costly, commonly blowing apart carburators and intake runners.
A wet system also has another solenoid to fail. Should the solenoid become plugged, or not open, the nitrous will inject without fuel, run lean, and blow your motor.
Without a good fuel pump able to supply enough fuel for your nitrous jetting, you will also run lean and detonate.

A dry system reduces this risk. However, a dry system puts more taxation on the injectors. In cases such as ours, where injectors are already being pushed pretty hard, adding nitrous will create fuel delivery problems.
A dry system which uses a computer is able to determine if the fuel pressure is to low, and not activate the nitrous, eliminating the risk of running lean.
There is also less solenoids to fail.
Clogged fuel injectors can also cause detonation here as well.

Seems wet systems would be hated, but in actual fact, they're not.
Wet systems offer much more availability of horsepower. Tuning of nitrous injection is fair easier, and able to be done per intake runner. Most of the negative "worries" of a wet system can be taken with a good fuel pump, fuel and nitrous filters, and some knowledge.

Overall, a properly set-up dry system is best for those who know little about nitrous (your honda boys.) But overall, a wet system offers more tunability, more power, and more flexibility than a dry system.

Need more info? Just ask.

Remember everybody nitrous(man i hate NOS too) is a power booster, not a power substitute. The fact that you get your power from a bottle that you refill from time to time is rather stupid to me. The only thing that i refill is my gas and oil tank.

Gasoline is needed to make power. Didn't know you didn't have to refill it.

Dude, stop trolling. There are plenty of threads already with people bitching about nitrous use.

Plain and simply, I use nitrous when it is needed: during a serious drag race. I don't need the hassles that go with driving a 400 rwhp car on the street all the time.

If you want to complain about the use of nitrous, fine, but I'll bet you anything that my car is faster than yours when its needed to, and I don't stupidly loud exhaust or an undrivable ride for the rest of the time.

Those who complain about the use of nitrous are simply ignorant about the subject. You've never used it, have you? And don't bother replying "I'd never use nitrous, I don't wanna blow my motor", b/c a properly tuned nitrous system will never blow your motor. If you're worried about blowing your motor while using nitrous, you don't know a thing about engine tuning.

Funny how my almost completely stock engine can handle an extra 220 horsepower from nitrous and hasn't blown yet....
