Let's see what there is to say?!
Why are wet nitrous kits or systems so much safer than dry. I could see why they used to be, but with the options they have now I just dont get it. I believe dry is as save if not safer than wet. Mabey you just can't teach old dogs new tricks. Please give me reasons why you think or know why wet is best because I can't find any.
You might see this on other sites, so don't get pissed.

From what the builders tell me, smiddy1 is that the wet kits spray each cylinder evenly where as the dry kit sprays throughout the air box which sometimes allows one cylinder to receive more of the shot than the other cylinders, which could cause some serious engine issues, instantly.

Properly setup with all the safety devices I think both are equal. It's all how much money you are willing to spend to set a system up right. I have heard of persons running out of gas using a dry shot and burning the motor. Fuel pressure switches and rpm cutoff boxes need to be installed.

i have been wanting to install nos myself , and been asking the same questions. i was told the same as fastest14 says. that one cyc gets more then the other and it out would stroke faster causing the engine to wear out .

My kit and allot of the newer kits have direct port shots just like the wets.


I think there are less issues to deal with on a dry shot. Less to go wrong. Steddy that's what I'm saying, you could put a fuel pressure switch on your factory line. I think you would run out of gas on a wet system just as fast as dry unless you are using a separate fuel tank. Still think dry will aways be the less expensive route.
I meant to add all things equal, all safety, boxes, electronics.......

You can set a dry system up with 4 nozzles so it sprays directly into each intake but of course it cost more money. The packaged systems have just enough components included to spray. They do not include any of the safety items or filters that should be installed on every system. NOS ain't cheap. I have about a $G in my system and could easily have spent more. If your drag racing, don't even think about spraying until you first max out learning how to ride the bike. It will just screw you up and make you worse.

I agree with you on all points, except the last. I think that depends on the size of the shot and activation. That still doesn't tell us why wet is safer or the best way to go.

Well I haven't used the bottle for the last 3 or 4 months just because of my last point and I know of a couple others at my track the feel the same way. Deciding what type of system to use greatly depends on how big a shot you plan on spraying and what type of bike. With a dry system you have to have a special map and then if you want to still ride the street you have to keep switching maps or spend the money for the new multiport hub. Wet system you just flip a switch to arm it. With a wet system you can also go with a larger shot with out fear of maxing out your injectors. Done right I think they are equally safe. Done wrong, BOOM!
Smiddy if you don't already have one, install a fuel pressure safety switch. Cheap investment for the security it gives.

I think the way I'm about to go is going to be safe and have allot more hp than people think you can go dry. I don't have the hobbs switch yet, but it was on the list. I hope this will open some eyes. If you want some details I'll hit you up.

Considering I was putting this in layman's terms, I was using the term dry as in not mixing the nos and fuel in a single orifice or the need for a second (fuel) solenoid. Dry as in using the pc (in my case) and stock injectors. And yes there is such a thing as a dry shot.....

I know exactly what your talking about, but technially there is no such thing as a dry shot.
I eventually will have a dry set up from hell, FMU, fuel pressure safety, two stages, etc etc looking for 150 shot or so..

I guess we'll have to agree to disagree on that point. On the other hand, I bet you could do without the two stages and the fmu for your 150 shot. Unless you're calling a fuel pressure regulator a fmu. With one solenoid.

I've read a lot of different opinions on both. Personally I planned on going with the dry shot with all the checks and balances to safeguard the motor. I recently had a mechanic friend of mine swear against them. He's really good with building motors, but I still think it was more his opinion than anything. I will install the muzzy dryshot kit because I already have their airshifter. Not sure what else I need to buy for the kit, but I've still got 11 months to finish the research.
FWIW, he said the dry shot was absolutely the hardest thing on the motor....?
The Turbo is truely looking better and better, I'll be perfectly happy with 7psi...

A dry shot is hard on the motor, just as hard as a wet shot of the same hp if it's not progressed. If the af ratios are the same, hp is hp, same stress. Progress them both , which one would be harder than the other? I money wasn't an object, I'd be leaning towards a turbo, But this is turning into a challenge.

Question, how are you progressing the dry shot and the fuel at the same time? Are you just progressing the NOS only and just setting your fuel for the full shot?

No instant rich box. pnc-3000. Hobbs is a manufactures name- honeywell / hobbs. It's a pressure switch you T off the fuel line to make sure you have your set pressure in that line, if not it will shut down the nos. I made the spray bar. There is a guy that makes them, they are a lil different, but they are for sale. He also uses different nozzles, the ones I have are for a dry shot. They sell them at schnitz but they don't have the high pressure ones we need for the factory fuel system. NOS has one also.

Well that is just a fuel pressure safety switch. How are you going to progress the fuel at the same time you progress the NOS to keep an optimum mix?

If you're adding fuel thru a secondary method, - extra injectors, wet fogger nozzles, or fuel nozzles, it's dry. Secondary fuel supply = wet.
Fuel supply thru factory injectors in stock location used to run the engine when off nos is dry. After market fuel injectors, upgraded fuel flow and pressure, used to run the engine while off nos is dry.
