i'm seriously considering a dry nitrous system but dont know which one would be best for me. i want one thats easy to use and more on the fool proof side. it seems the venom and zex systems are more of the fool proof kind of nitrous sytems but i wanted to hear from people that had either one of these systems. so lets hear which system you all like better.

 

Can I ask why you want a dry kit? Wet kits are easier to tune and a bit safer, well in my opinion atleast. Although I would go with zex over venom anyday.

If it matters at all I went with NX.

 

Id go with a wet kit and NX.

 

+1 NX wet FTW

 

I thought dry was safer. You don't have to worry about pooling in the intake.

 

yeah i want something on the safer side. i just want a modest kit with maybe a 75 shot or 100 shot max. something that i wont have to get a tune for

 

you really wont have a problem with a 75shot wet as long as its sprayed above 3k rpms. If you really have to have dry i would do the ZEX kit.

 

Wet is safer, do some research.

 

i've always heard dry was safer but i havent done that much research. isnt wet harder to install?

 

so i definantly would have to get a tune with a wet system?

 

stay away from either zex or venom. Go with a nice wet kit. Much safer and no you dont need a tune to run it. You need one even moreso with a dry kit.

 

i thought zex and venom were supposed to be good because they kept you from leaning out? im not looking for a badass nitrous kit to run at the track i just want a lil 75 shot from time to time to take car of those ugly *** camaros

 

If you dont get a tune with the 75 shot, then you arent doing it safe in my mind. Too rich is bad just like too lean is. PLEASE at least put it on the dyno and look at the a/f.

Ive said it 100 times and Ill say it again...
NX kit with Gen X2
Focus pump
NGK TR6 Plugs gapped at .030
Window Switch
TUNE

 

but i thought the zex and the venom systems monitored your air to fuel ratio so you wouldnt lean out?

 

Venom does so it is techinly safer. ZEX just has a built in Fuel pressure saftey switch so when the fuel psi goes down it shuts off the nitrous. Seriusly though a wet kit is easy to install no other fuel upgrades needed with a 75 shot.

 

Yep, nothing is needed fuel wise with the 75 shot. Maybe a focus pump to help the lean spike, but not 100% needed. Just get it on the dyno and check out that a/f.

 

yeah see thats what i was trying to avoid, having to get retuned. Tune = Money


not tune but dyno time

 

A dry kit will require more tuning then a wet kit though. Any power adder will cost money, theres no such thing as a cheap one. You do it cheap, then you pay later because something breaks.

 

i understand that no power adder is cheap but as i have read the venom 1000 does not require a tune what so ever. as far as i know the zex dry kit does not require a tune either i was just curious if anyone had either of these kits on their car and how they performed. i agree with you 100% that if you dont do it right the first time your ****ed but what about these dry kits that do not call for a tune?

 

With the dry kit you have to upgrade injectors and it sprays before or after the MAF. Then you have to rely on the computer to adjust the a/f for that. Im not sure how the Zex or Venom dry kits work that they dont require a tune. But you cant upgrade injectors without a tune so.

 

from what i read on here about the venom 1000 it said that it constantly monitored a/f and if it got too lean it shut down

 

I've had both Zex and Venom kit's on previous cars along with NX and NOS and now Compucar. The Venom kit is junk plain and simple. Your paying for their name more than your paying for quality. Many friends have tried the Venom kit before and got rid of it a few days later to a month later...so what does that tell you? As for ZEX, I've had that kit on 2 of my cars and it worked out alright. Using a Dry shot from ZEX or any other company will not give you the full effect that a Wet kit will. If you do a 75 dry shot with a ZEX kit....your gonna see MAYBE a 35hp gain!!!! If you go buy a good NX or NOS or even Compucar wet kit and do a 75shot....you will get at least 60 or more hp out of it. I've seen several cars gain over 100hp on a NX wet kit. With ZEX dry kit, you hook up 3 wires....TPS, power-to switch, and a ground. Pretty simple and splice in 2 vacum lines for it to work safely with a fuel pressure vacum. Honestly it would take you maybe an hour to hook up being your first time. The Venom kit has a lot of different relays and crap.

Going with a Wet kit has a bit more work involved but like others have stated it works a heck of alot better than dry. Yea Dry is harder to tune unless you have a S-AFC controller which allows you to fine tune your Fuel maps in 200rpm sections. With a Wet kit we usually go 1 size larger pill on the fuel side just to be safe than what is called for unless the car has been dynoed before and we know how the A/F is. Altho if you dont wanna get it on the dyno, go buy a Wideband A/F guage and be safe all the time and monitor your A/F without being on the dyno at all. In my opinion, throw a NX wet kit with a 75 shot and have fun with it. Stay away from ZEX and Venom stuff unless you want to waste your money and time and not get the full effect!

 

Thats a good point I forgot to menotion. Youll gain more with a wet kit compared to dry. Youll also gain more with a NX wet kit compared to a NOS wet kit because NX rates their jets are the rear wheels compared to NOS where they rate theirs at the flywheel.

 

Yea i forgot to mention that 03gtmustang, bout how NX rates there stuff better than anyone else and garuntees the most power gains. We did a 75 wet shot from NX on a B20-vtec civic and gained over 100hp at the wheels!!!!!

I guess once you've had nitrous on every car you've owned and had all the top named kits, you know which ones are the better and whats not so good. My 1st car when i was 15 was a civic i was building so when i got my license i had a nasty car.....Had nitrous on it while i had a learners permit lol. I'm 23 now and i've owned more Nitrous kits than one could imagine lol.

Also a couple friends and myself put a 80-dry shot on a Wal-mart Homelite brand weed eater.....took it like a champ and still cuts grass! Did a 125 NX wet kit on a Briggs & Stratton riding mower.....still cuts the backyard and does wheelies a year later and this was done several times in an attempt to blow it up which seemed to never happen yet.

 

Theres a vid out there of someone spraying a mower or something a bunch of times and it still kept working.

 

Holy hell, not this argument again - LOL

Seems like everyone has an opinion and as always, no one seems to fully take into consideration the goals of the poor guy considering this as a power adder. What is the best choice for one application, is not the best choice for another.

Wet or dry, there are benefits and drawbacks of both. There are some very high hp applications that use dry, but generally you will see wet used when larger shots are desired. Dry system are generally simpler and have more safety features built in, BUT they all use some sort of mechanism for managing the fuel injectors to try to ensure a safe a/f. These systems are generally fine especially when using a 75 shot.

Thing is, when you first start using the spray, the 75 is fun. Next thing you know, you will want a 100, then a 125 etc... and the Zex and Venom systems just can't reliably deliver safe power at those levels.

But, if you want a 75 shot and are working on a budget, spending $600 on a Zex or a Venom will get you there. No dyno tune, no chip, no nothing. Just the system and a full bottle.

On the other hand, if you want to build a serious system and run an NX Wet, plan on spending $2500. I always get called out on the carpet when I say this, but a complete kit runs $1200. Then you need a chip and a dyno tune, throw in some guages and before you know it, you have spent every bit of $2500. Naturally, there is always the used route, but that's like criticizing someone for spending $25k on a new GT, when they could have bought a used '96 for $6k.

Which system is safer wet or dry? I can not possibly see how one can be safer then the other. There are blown motors resulting from both options and I don't think anyone has ever comissioned a survey. All of these systems can fail. All of these systems rely on moving parts, electronics, etc.... all things that can fail. There is no sure thing. All you can try to do is stack the cards in your favor as best as you can and keep the odds on your side.

I might also add that I would rather have a blown intake then a piston or two with a hole burnt in it. I would also prefer to have a one fuel feed point rather then 8....thus giving the nod to wet systems.

As far as one system making more power then the other, this is in part true, but also hogwash.

If you add nitrous with a set amount of fuel, you will make a set amount of hp. Wet systems do not make more power, it is all in the amount of juice you add. If a NX Wet system rated at 75 hp, makes more power then a Zex rated at 75 hp, it is because the NX system added more fuel and nitrous then the Zex system. It is all in how the systems are rated, not because one system is better then the other or somehow magically makes more power.

Just know that NX rates their systems to be accurate to rwhp and you must also have the correct bottle pressure. Throw in a Zex 75 shot system (dry) w/o a bottle warmer and you will definately not expect to see 75 hp at the wheels, BUT that is because you are adding less nitrous.

 

now those were the kind of answers i was looking for. like i said i was just looking for a kit that i'd use maybe once a week tops and at the max a 100 shot. just looking for a kit that is on the safer side cause im not really trying to make a dragster out of the thing. still need it to get back and forth from school. ill prolly look into getting a NX wet kit though. just gotta find one in my price range. thanks for all the help guys.

 

Ok, tell me why we have dyno tuned many cars on both wet and dry kits, and the Wet kits always make more power? I did t a zex dry kit on one car...fine tuned it on the dyno with a S-AFC controller and changed the fuel setting in 200rpm junps....couldnt have fine tuned it any better. A 75 dry shot with 1400lbs of bottle pressure made 36hp gain to the wheels. Now I did a zex wet kit 75 shot a couple weeks later on the same car, didnt change anything besides backing some fuel out. The car made 72hp! So tell me how a Wet kit doesn make more power? I see Nitrous cars on the dyno all the time usually 1 a day sometimes more, and all of them are tuned and the ones on wet shots ALWAYS make more power than the ones on Dry kits.

 

You are missing my point:

Nitrous + Fuel = Power, right?

If you add more nitrous and more fuel, you make more power right? So long as the a/f stays the same.

If one kit adds more nitrous and fuel then another, then you will make more power. If you ran Kit A and then ran Kit B and Kit A made more power it is because Kit A added more nitrous and fuel. It does not matter if you want to call it a 50 shot, or a 100 shot. It is just a name....a marketing ploy.

You could take any two kits that are supposed rated the same (say 100). If one kit makes more power, it will drain the bottle faster thent he kit that makes less power.

Wet or dry, it does not matter. There is nothing magical about wet kits....if there were, then we could all be very reach people because we would have discovered how to create energy.

Please keep in mind that my comments assume that a/f remains constant. If you want to say that wet kits are easier to tune and thusly easier to extract more power from, then that is a different subject and could be the case....I do not know.

I am not trying to cause a fight...mayebe we are talking about teh same things, just a different way.

 

I will caution you....the power is addicting.


Many years ago, I mentioned to a friend of mine who was serious into bicycle riding that I wanted a bike. He took me to some bike shops and showed me bikes that were $2500 to $4000 and was like "dude, don't waste your money on a piece of crap....this is what you need."

Thing was, I was not, nor have I ever been into serious bike riding. I did get a bike and I paid $200 for it. That was in 1993. I still have the bike and I ride it regularly with my kids. Works great.....serves the purpose well.
