Opinions on the Venom N2O System

[Archangel]

I know a lot of people like the NX System, Safety is my #1 concern.

http://www.venom-performance.com/nf/images/v339.png


The worlds most advanced nitrous system to date.The system is built using Venom's Patented closed loop fuel control system which ensures the proper air/fuel ratio under all operating conditions. Featuring closed loop fuel operation utilizing two dual processors to control nitrous module. Special safety features insure proper air/fuel mixture or the injection of nitrous is shutdown before catastrophic engine failure. Kit comes complete with all necessary hardware and installation instructions. VCN-2000 utilizes stock injectors for fuel enrichment during nitrous injection and is available for all late model vehicles that come equipped without a fuel return line.

Introducing the the only programmable PC-based nitrous system on the market today. A truly innovative product designed to take your car or truck to the next level of performance. adaptable to either street or track driving, Venom PC-Nitrous system is the ultimate performance upgrade with results that will blow you away. The Venom PC nitrous has several key advantages, our system is completely programmable by the end user. The user simply plugs the nitrous controller into the serial port of their PC. Using our software the user can configure the nitrous to operate in three various modes of operation.

The VCN-2000 is the safest choice by far. When nitrous is introduced , additional fuel is required to ensure the proper air/ fuel mixture is obtained. Without the additional fuel the mixture would become lean causing detonation of motor. Our system utilizes the existing injectors to enrich the air/fuel mixture when nitrous is added. our systems adds an injection pulse width after the computer has finished its pulse. the pulse added is the product of how much nitrous is introduced. this is calculated by the VCN-2000 module.

Sort of like a ZEX kit I suppose, I like them and have seen good success with them.

[Pull_T]

That kit makes things more complicated than need be I think.

I'd go with an NX kit and just keep the shot size down (75)

nx. accept no substiutions. (coming from the nitrous whore) ;)

Ok give me a scientific explanation to why. I need pros/cons over the default "ZAINO Ownz You" type of answer.

[Erich01GT]

I previously considered purchasing that on my old stang but ending up going w/ the ZEX since the ZEX was a lot cheaper and figured all the gadgetry w/ the Venom is more hassle than what it's worth. The system also involves wiring up to your injectors and a bunch of stuff... Plus i couldn't really find any imperical evidence from anyone who had the system, just the typical advertisments by Venom for their system and less than a handful reviews on it.

[colt .45]

NX or nothing.

[matttm63]

Noszle.
For more info check my post in your other threads. Also NX has a direct port kit coming out too that has an even cleaner looking set-up.
As far as being safe I think the Noszle kit is the safest one out.

[FearFactor]

I don't think the NOSzle kit is out yet for the 4V's, is it?

Not that I've seen, NOS said it was coming out, but I don't know if there's a big enough market for it to be worth it for them.
But I think you could piece a kit together, they sell those Noszles seperately now.
NX said they were releasing a direct-port kit for the 4V's, but who knows if that'll happen either.

here is my scientific explanation:

Nitrous flow and mixture are inter-related and depend on each other to assure safe use on spray. The Venom kit manages this with an O2 sensor and a proprietary computer that (has already been said) hooks up to alot of things on your engine, including your fuel injectors. This is because it is a "dry" system, meaning it sprays nitrous ony into your intake and relies on the fuel injectors to spray the extra fuel and make the mixture safe. This causes a few concerns and i'll get to those in the next paragraph.

Since dry nitrous systems rely on your fuel injectors for the extra fuel, you are adding another point of failure in your chain. Relying on the factory equipment to do more than they were designed for by either raising fuel pressure (ZEX, NOS) or by increasing the duty cycle (I assume the Venom kit does this, and that is why it connects to them directly). Once you take fuel delivery out of the nitrous systems hands, you are only waiting for failure. All it takes is a clogged fuel injector for a split second, or for it to stutter, and your cylinder has become very lean and you WILL most likely drop a piston. Different companies have varying methods of controlling how much nitrous gets sprayed as well. For this paragraph we will stick to dry, and I well get to wet systems later. The NOS system relies on bottle pressure. If your pressure is in the correct range, it raises fuel injector pressure a specific amount, and you are good to go. But once again, relying on fuel injectors. The ZEX system uses bottle pressure to guage how much nitrous to spray and how much to raise fuel pressure to keep the mixture correct. This is all fine and dandy if you don't care about consistency, but once bottle pressure drops as you reach empty, fuel pressure will drop as well, and you won't get a full shot every time. You will get less and less, unless you have a bottle warmer, and even still, towards the bottom your nitrous flow is less than when it is full. The Venom kit uses the reading from the O2 sensor and bottle pressure to determine how much fuel to spray, and we all know how accurate A/F guages are, not to mention all the extra wiring that could go wrong or malfunction while you are spraying. To me, it doesn't seem worth it to re-invent nitrous delivery. Sure the Venom race car is fast, but i HIGHLY doubt they run a dry shot on a professional race car. *Note to self: lookup Venom car's nitrous delivery system*

Now, to focus on why the NX system is better.

The Nitrous Express system is a wet kit, which makes it inherently different from NOS, ZEX, Venom, and TNT systems because it uses its own solenoid and nozzle to spray the nitrous AND fuel together from the same point. There are some concerns that the wet systems are more dangerous to your intake manifold because of fuel puddling. This occurs in the 2v intakes because of the tight turns the mixture has to make to get to the cylinder heads, but I am not sure if the same can happen on the 4v because the IMRC changes with RPM. Someone can add to this... At any rate, if you spray above roughly 3k (which is the generally accepted rpm, and you will rarely find yourself below this except in 1st gear from a start) the intake velocity will be more than enough to assure the fuel and nitrous make it into the cylinders together and without puddling.

Since the NX system draws from the fuel rail rather than relying on injectors to do the work, your only point of failure is your fuel pressure (which is just as much a concern in the dry camp as well) and the fuel solenoid. That's it. No complicated electronics or metering to mess things up. Keep the shot at 100 or less and your factory fuel pump will do just fine. If you want to spray higher, upgrade your fuel pump and you are good to go. While we are on the topic of solenoids, the NX ones are very large in comparison to other brands. My purge solenoid is bigger than the main ones in the NOS system. Simply put, the larger the solenoids, the more wire is wrapped in their coils, and the stronger they are to open and close, causing less problems down the road. Believe me, with 1000 psi wanting to hold them open, you want them to be as strong as possible to make sure they close when they are supposed to. Otherwise, you could have a very expensive paperweight under the hood.

Now, onto nitrous flow and control. The NX system has been tested vigorously to assure results would be repeatable. The NX system has a simple way to control how much nitrous and how much fuel will be sprayed into the engine. Bottle pressure. When you first fill your bottle, and have about 11 lbs in it, the first spray is always the best. why? Because pressure is right where it should be, (950-1050 psi) and then nitrous is nice and cool. In that pressure range, the laws of hydrolics don't change. At a specific temperature, through a specific orifice, the same liquid will flow the same every single time. (you are actually spraying liquid nitrous oxide until it reaches the nozzle, then it boils and becomes a gas) Given this constant, a specific amount of fuel will be delivered, because the fuel system pressure will not change either. Yet another constant. You control how much of each with jets and a jet chart. This is why NX will be more consistent, simpler, and just as safe, if not MORE safe than a dry system. Not to mention wet systems generally "hit" harder when you get on the juice, becuase the mixture is put together at the nozzle rather than mixing together as they enter the intake port.

So there you have it, my scientific explanation as to why the NX system is better than the Venom, NOS, and ZEX kits. :up:

i hope i didnt forget anything. :D

[D0T C0M]

garrison tried a 100 shot venom and he is now w/o a motor for a while. of course, also running 14lbs of boost doesn't help, all the while on a stock bottom end.:retard:

[Black03Mach]

nitrous is like sex...you dont want it dry you want it wet ;) :up:

btw casey excellent explanation!

[FStop]

thanks b. i hope that all made sense. i did ALOT of research and reading before going with NX and i don't regret it for a SECOND!! :bang:

[Archangel]

WOW Casey! Thanks bro! :up:

[Russ]

Casey, you running a custom tune also? I have seen some impressive results with the NX kit, but I think personally I'll wait for their direct port setup. I've still got suspicions about fuel puddling in the intake.

[colt .45]

Ive had no fuel puddling since Ive had the kit for a lil more than 2 years.

i think its more of a problem with the 2v

nope, but rest assured when the NX direct port integrated rail system comes out i'll be all over that shit like a fat kid on a cupcake :D

[Quikcpe]

how about fuel puddling in a 5.0?

if i get a wet kit im not going to install it.

i cant decide what i want either. zex or nx.

thats like not being able to decide between a bicycle and a harley. if you haven't done your research, and understand what i wrote, don't get either.

dry kits are for the newbs, nx, compucar, nitrous works are for the big boys.

and for the last time, NO YOUR 5.0 INTAKE WON'T PUDDLE, espescially if you spray above 3k or so (which you should anyway unless you wanna bog your motor and break shit)

[thumpin347]

the stock manifold's runners are short enough where you wont have to worry about puddling. now you are interested in the track heat, from what i understand...the trick flow manifolds seem to be large, where puddling may be a factor...but there are plenty of 5.0s runnning TFS manifolds and nitrous. to me, the manifold to get is the typhoon. its great for budget builds, and leaves you with money to work the shit out of it.

[texas89lx]

12yos, how many times have i told you tha 5.0s dont have tow orry about puddiling? jesus h christ

[Andras]

Wizard, that's a nice write up.

The fuel solenoid is just a big a point of failure as the fuel injectors tho, and in my times at both MIR and Capital here in MD, the only failed solenoid I've seen was a NX fuel solenoid that stuck open.

Now, the 99+ Mustangs with a returnless system don't really have the best setup for a dry kit as my return system, but if I get a failed solenoid, the worst that will happen is I go rich ( if S1 works, and S2 doesn't; If S1 fails, nothing happens).

thanks for the compliment, but you are comparing 1 AFTERMARKET piece that is made to do one thing, open and close (briefly, and probably not that often), to 8 units, that are factory, and were never meant to flow more fuel than ford built them to. either by increasing fuel pressure or duty cycle, is just asking for failure IMHO. :)

oh yeah, and returnless fuel systems suck! ;)

[codycr6]

My 5.0 doesn't seem to have a puddling problem... ;) everone should just get a kit that doesn't have a puddling problem, no matter what the intake! :up:

i caught it, and saw your setup...but others might not have.

[Project91GT]

I bet i will ge tthe biggest r u stupid on this ? But i have my nozzle in my air filter and a button i push when i want to spay.I like it cause i control when it spays and dont. For the fuel it relies on the maf to compinsate for the nitrous. The only problem i have is i am haveing a hard timer keeping my nozzle styait and it keeps spaying out the side of the filter resulting in not getting the ful shot of nos. Ok now here comes the bashing lol.

How is the nossel in the filter? is it taped? if so just use some thread loc on it and you should be fine

[Blue93Trunk]

You know ZEX make's wet systems, right? It's just a 2 into 1 nozzle spraying into your intake tube after the MAF...

NX's kit is the same, right??? Does NX make something for 5.0's in a wet system that's right under, or at a 200 shot, that's NOT a plate system??

The only reason I'd be scared of fuel puddling on 5.0's is the fact that the runners take a 180 turn before they come down and enter the combustion chambers.....But like Casey said earlier, if your turning more than 3000's anyways, you shouldn't have that problem... ;)

[FStop]

zex's wet kit is really new. look at the date on my post..it was waaaay before they came out with a wet kit. besides, i'll take nx's reputation over zex's any day. :)

Give Casey one more bump....

Was that my NX fuel solenoid that you saw stuck open at Capital? My stuff's been stuck open all summer :down:. Should be getting it fixed this winter :up:.

[GarrettW]

this is not a bump.

I'll sticky it so you guys don't have to keep bumping it. I'm going to clean it up a bit so don't get all excited if you see a few posts disappear.

[priji]

Than you
