Whats the difference between a Wet Shot and a Dry Shot? Why would you want one over the other? Thanks!

 

wet shot includes fuel in its injected potion, dry relies on fuel enrichment from elsewhere...

 

You would want wet over dry because the design of most Honda manifold is such that number 3 get the most flow. With dry, nitrous in injected by itself and fuel enrichment is control by increasing fuel pressure. The increase for fuel is the same for all cylinders where as the nitrous is not distrubuted evenly. This is a primitive way to increase fuel, its the same thing as a FPR for a turbo. Not the best, but it works.

With a wet system, you have fuel and nitrous introduced through a common injector. The high pressure of the nitrous helps atomize the fuel which travels with the nitrous through the manifold for a more even distribution of fuel and nitrous.

obd2 civic dx and cx have a manifold that does not have the air flow issue so dry will be ok there if you must.

Sorry Evil, but you have it wrong.

There are three types, Dry, Wet, and Direct Port.

Dry: Single nozzle, Just nitrous.
Wet: Single nozzle, Fuel and nitrous.
Direct Port: One nozzle per cylinder, Fuel and Nitrous.

 

FIRST AND FOREMOST, GET A NX SYSTEM...
anyway, these are the main types of nitrous kits...
1)dry
2)wet w/ fogger
3)wet aka direct port with a fogger per cylinder...

the best nitrous system is direct port but is expensive and labor intensive, the next best thing is single fogger wet, but it has to be using a fogger that is proven to not puddle. NOS brand foggers DO puddle if used for single fogger w/o turbo, that is why NOS does not offer a single fogger kit for NA cars...NX brand, on the other hand, only offers single fogger kits, and thus, has had great success upstaging NOS's supposed "reliability". The NX kits have unparalled atomisation, and basically everything about their kits is better engineered than NOS...

You will see more than 1% of people using a wet system. Why? Because it's better than just a dry system, and it's MUCH easier and cheaper to set up than a direct port.

True, anyone serious about it will use direct port..but lets be honest. what percentage of honda nitrous users are "serious"? Most of them are just running a dry 55 shot on an otherwise stock engine (maybe I/H/E). The ones that are a little more serious, or know what detrimental effects a plain dry system can potentially have use a wet system...And the ones that have lots of money, or are part of the NHRA circuit use direct port.

Either way, there is still a big difference between direct port and wet.

 

It looks like everyone forgot to answer your question when they started fighting about how many different nitrous types there are…..seems like this happens a lot.

Anyone what are the pros and cons of each system?…well here its is.
1. A dry system is relatively easy to set up and your average do-it-yourselfer can complete it in a day. A dry system injects a single stream of nitrous into the intact track and relies on the stock fuel system to add the extra fuel. The good thing about a dry system is that you can put it as far away from the throttle body as possible and this will cool the intake charge significantly. This is a great simple system and will add that needed boost to a stock car.
2. Wet systems incorporate a nozzle that injects both nitrous and fuel at the same time. A “wet” single nozzle system can be seen on turbo cars because the fuel/nitrous mixture can lower intake air temperatures before it enters the intake manifold but you must remember to put a “wet” injector close to the intake manifold because you are adding fuel. Add it to far away and you just saturate you intake tube with fuel(backfire). This system provides greater tuning and more power over a “dry” system but takes a little more installation time.
3. Direct port nitrous injection works on the same concept as direct port fuel injection, inject the fuel right before the cylinder. Great horsepower, great tuning, and the best bang for your buck. However, direct port nitrous systems are usually in the 200+ shot range, which should not be done on a stock engine.

Recommendations: keep it simple and go with a “dry” system

 

I will assure you that the reason NX is doubling its profits every quarter is not from 99% of nitrous users NOT buying their product...ask brian havins of NX how many square feet his house is, i'm sure he did not get it from NX's exclusivity to single fogger technology failing miserably...

The biggest misconception about dry kits is that they are reliable...the fact is, in a perfect world, they would be, but in our world, there are way too many stressors on a stock fuel system to expect it to be able to fuel PROPERLY and promote perfect atomisation from simply getting a boost in fuel pressure...

Wet single fogger kits like the NX line give you perfect atomisation, therefore eliminating puddling, ensuring equal distribution AND rely on perfect fueling all the time w/o overstressing the other fuel components your car needs to operate safely.

Direct port is superior to all nitrous kits in NOS's line, BUT, even on many fullybuilt street/strip applications, it is an unecessary expense and is indeed overkill...as compared to what a thoroughly engineered single fogger kit like NX can provide for you...

 

first of all, i answered the original question several times already...
anyway, teken-
people are quickly realizing that NX r&d has indeed proven itself with making better technology available, technology superior to NOS dinosaur tactics **single fogger wet has been proven to be bettter than NOS dry nozzle and perform as reliaby as DP NOS w/o the added cost and hassle**...the sales numbers only back that up; my firm reps the NX line, bleve me, they walk hand in hand in this instance, NX quality/ sales volume increase...even their remote bottle openers, purge setups, all of it is superior to NOS... in design and function

teken, you did give your opinion on the original question but, some things you said about single fogger wet and its reliability/effectiveness dont ring true in the real world...
"Wet: System uses a individual direct jets to each cylinder for even nitrous distribution..." -you totally omitted single fogger technology
"You will not see 99% of the users going with the 2nd option you just listed... (2nd option=single fogger wet)" -umm..not true for sure sa indicated by NX growth
"My intent was to answer the Q with the lowest budget set-up... To applying and using the method that *really* does work given the proper application"-single fogger kits from nx cost less than NOS DP and are not overkill, in cost and function, like NOS DP, and perform better/more reliably than nos dry for minimal cost increase...
