what is safer? wet or dry kit? or easier on your engine? im only gonna run a maximum of a 75 shot....do you think my stock fuel pump can handle y pipe, b pipe, cat, intake and a 75shot? or should i tone it down to 50 or 60?

 

IMO a dry kit is safer because it doesnt require mixing of fuel an nitrous before it's injected- just increases fuel pressure- so for installation purposes if you're doing it yourself, unless you've done this many times before, dry kit is much simpler too. 75 shot is kind of pushing it on the stock pump...you could run on it, but I wouldnt recomend it. You should get a high volume fuel pump and a new fuel pressure regulator, and new plugs too (colder) and regap them. I dont know a whole lot about wet kits, but for a dry kit, that's what I would do. A 50 or 60 shot is ok on the stock pump -I'm still at a 50 right now.

 

so a 60 shot is okay? even after almost all the bolt on's a maxima can get?

 

I'd say you're ok. I have I/Y/E w/ the 60 and it's fine. But I have a walbro 255lph fuel pump waiting to be installed, so I can run a MUCH higher shot.

 

why would dry be safer? venom?
the mixing occurs int he combustion chamber. your mix wont be pure and spead into the cylinders evenly. your intake manifold and throttle body will be hitting pure n2o, i dont see how dry is safer?

how is it safer in your opinion if you know nothing about wet kits as you say>?

 

a dry kit is very safe i used a 60 shot dry and also 75 dry with no other fuel upgrade and plat plus 4 sparkplugs .. and exhaust.. holley recommends not going higher than a 75 shot unless
you get dynod first... but dry 60 shot seems the safest per stillen...

 

plain and simple the nitrous can puddle i believe in your manifold.. but what ever the case the wet shot puddles which can cause combustion, and the dry shot doesn't... also with the dry shot you dont have to worry about the fuel not spraying with the nitrous..which can cause the engine to lean and detonate...

 

Yes and on the dry system you have to worry about FPR, FPR not raising fuel pressure enough, fuel pump not pumping enough pressure, injectors sticking due to excessive fuel pressure etc. I have not heard of a single case of fuel puddling on here and a lot of people are running NX wet kit. And even then I'd tke backfire over detonation.

 

Thats funny, about a year or so ago I came on here and asked if anyone was using the NX kit. One guy responded, Shadow, who said he installed one on his girlfriends car. Everyone said it would puddle and cause backfiring etc.

Guess what that is totally BS created by guess who? NOS who at that time did not make a wet kit. Guess what, NX was so successful that both NOS and ZEX now make a wet kit, what does that tell you?

Regardless I went ahead and bought a wet kit and it is far superior to NOS in quality and performance, I know because I was using NOS before I got it.

The wet kit is also just as easy to install and is MUCH safer imho because of what was mentioned by Maksim. Injectors are manufactured to run at one pressure and jacking them up to crazy pressure levels can cause all sorts of problems for them and your fuel pump too. Wet kits run at stock fuel pressure so you can run a much higher shot before you have to upgrade you fuel pump. The NX solenoids are 3 times as large as the standard NOS ones and have a lifetime guarantee, they will rebuild them every year for free if you pay just the shipping. etc etc

Anyway I don't want to get into any argument about who is the best but I have had both and wet is the way to go. I might also mention that it does not require any tuning because the fuel pressure is constant and the same fuel/nitrous ratio is being fed at all times. With a dry kit the fuel pressure can be anywhere for the same jet on different cars and must be adjusted to get the correct pressure, its a great adventure for some people.

 

true,true.... i never heard of anyone detonating from a puddle either..
but i was stating what the difference is according to the manufacturers..
the true choice is a personal one, when it comes down to it...

 

Yes, both are safe if you install and tune them right, both will blow stuff up if you don't know what you're doing.

 

I personally have never used a wet kit and have never used one. I know of people who do and how it operates. IF he is going to install it himself, he has less of a chance to screw it up by going w/ a dry kit, it's very east. I just said in my opinion...that's all, and take it for what he likes. Personally, for something like this, I wouldnt be relying on people I've never met/know for information because the people responding may be as clueless as the person asking. I was just offering what I know

 

Both kits actually install almost identical to install. The only difference is that on the dry kit you have to T into the vacuum line to fool the fpr into running crazy high pressures necessary for injecting the extra fuel required. On the wet kit you have to get your fuel from the fuel supply line which is also necessary for a fuel cuttoff switch for both wet and dry so cutting into the fuel line is necessary in either case for a safe setup.

Where the big difference lies for the novice is that the wet kit is idiot proof for tuning just put in the two jets listed for each shot and thats it, perfect A/F ratio.

With the dry kit you have to fool around with the jets in the vacuum line to get the correct fuel pressure because the same jet does not provide the same pressure in every car.

 

I really want to get a wet kit but dont know anyone around here to help me install it and dont feel like payin $150 for the local "speed" shop to do it. I also dont wanna buy a kit from the web and not get all the parts/right parts i need. From everything I've read and all the shops Ive talked to they say wet is safest. Or DP but I dont wanna drill in my manifold. Why cant I have a neighbor like Jime

 

I could do it and i live up your street. As long as you have a drill and a beer i'm set to install.

 

True, maybe we better wait to open the beers till after the install

I still gotta come by and check out your completed set-up.......
