Ive been debating which setup to go with.. DRY or WET? alot of people here are on the ZEX kit.. but this guy is saying that DRY kits are the worst. Is he right? can anyone debate his comments? HE seems like he knows what he is talking about.

QUOTE FROM EMAIL:

" Where you have been searching for information on nitrous kits has obviously not been the right place. The ZEX kit in my opinion (and I have run a lot of nitrous on my car) is the worst system on the market. Dry kits use additional fuel pressure at the injectors to acheive the extra fuel required to run the nitrous sytem. This then makes the car and nitrous system rely on small stock injectors to provide enough fuel for the entire system. It also increase your fuel pressure to 80+ psi at the rail which is very high. My VR6 injectors failed twice on my car before I figured out what was doing it and switched to a wet system. If you understand how fuel pumps work you will know that flow drops with pressure. As pressure raises flow reduces so it's very hard on your fuel pump and also increase the chance of blowing up your motor as you up the shot. Your stock fuel pump goes to almost zero flow at 100psi so guess where it's at when it's trying to pump 80+ psi? A wet system uses your stock fuel pressure and can run a much larger shot wet than you can dry and not drop the pressure on your fuel pump because your not upping the pressure on your injectors. A wet system runs totally seperatly of your engine and doesn't mess with the fine balance that makes your motor run perfectly. Also the garbage about fuel puddleing in the intake manifold is old crap from NOS who can't design a proper nozzle that atomizes fuel correctly. I have run 150hp shot through the maxima and had no nitrous back fires that NOS is famous for over a 75hp shot. That's why I sell NX. It's the best system on the market, and I am authorized to sell NOS and ZEX just choose not to because of experience. That maxima I spoke of is acctually my fathers car who used to have a dry kit. Honestly his car with a 100hp dry kit went 13.7 we put on the 100hp wet and went 13.1 the very next weekend. The car now runs 12.6 with some weight reduction and
fine tuning.

There is literally no tuning involved with nitrous, just plug and run.. We install other kits for 200-400 bux depending on where you mount it. Take it from me, even if you don't buy from me or have me install your setup, buy a single nozzle wet NX kit and you will be very impressed. Put it this way, NX doesn't even sell a dry kit because they are crap plain and simple.

Sorry for the long email, just thought maybe you could share this knowledgewith others you talk with on the internet. (though I know 10,000 people will likely argue with me on what I say but i'll bet 9,999 of them have never run nitrous on a car ever lol...)

I would agree with him - Besides here on a-cl ...Everything I read says that a Zex kit has some of the worst quality parts (jets) Along with the fact that as you said, wet kits tend to put more power to the wheels...

But, I do not have any personal experience - It is all what I have read and gotten from tuners and speed shop.

 

Hes charging $1200 for the NX kit + install which i think is a good price. <BUMP>

 

Whoa - A stretch would be $1200 installed....You can get a new in box kit from Ebay for ~$500 and you can get it from the NX website for $775...

Is he including anything like bottle warmer, remote bottle opener, purge kit, or ignition control devices?

 

bottle warmer ~$100 bucks extra
purge kit ~$80
MSD Ignition control timing safety device ~$120
And then there is this "pill" thing used in conjunction w/ the MSD ignition control unit which will run another ~100
----
Install (with purge, and even a remote bottle opener ($~200)) shouldnt be more then $300

So with MOSTLY ALL the bells and whistles(safety devices) you are looking at an installed price of (AT MOST) - $1675

If you go w/ a kit from Ebay and just do the basics with NO extra frills and safety devices - You can expect an installed price to be around ~$700

 

MC22.. i forgot to mention its $1200 CDN = around $850 US hehe.
Ill need an MSD Ignition control timing?? how come? even if im only planning to go with a 55shot?

 

Well, from my understanding - Our limiter is an ignition cut off rev limiter - NOT the other type, which is fuel cut off - So, it is still possible to run too high and go lean - which as Im sure you know or have read , causes problems...The MSD unit would cut fuel at a set RPM and prevent this from happening....

But - This is what I was told from the local speed shop guy and he may of been trying to make an easy sale...Either way, PLEASE ask your local shop and let me know, Im seriously debating nitrous and if I can get the price to sound right, Im gonna go for it

 

THis is his latest response let me know what you think. The wet kit sounds better and better.

"The problem with the ZEX kit is the control box. When you have all the solenoids inside the box you can not clean them etc as needed like you can with any other kit. That is the weakest part of the system is the fact that everything is housed inside a BOX. And the part about it controlling air/fuel is totally bogus. The way the system works is that it bleeds a certain amount of nitrous through the vacuum line you hook up to the fuel pressure regulator which applies pressure to the fuel pressure regulator
closed longer thus creating the extra fuel pressure needed to keep the air/fuel ration inline. If your bottle pressure goes down it just applies less pressure by nature that the whole system is running on less pressure, not that it's doing anything special in any way at all. The NOS 5123 dry kit does the exact same thing, but that is almost something that is automatically done by nature of how the nitrous kit work, not because ZEX has this magical system. In the end it's just a crappy dry kit which is no different than the NOS dry kit.
If guys run mid-low 13's on a Zex kit they would run faster with an NX kit with the same HP. I have ran both systems on the dyno and a 55hp shot of ZEX puts 40hp to the wheels, NX kits are guaranteed to be within 2% of the claimed HP at the wheels and our 50hp NX kit actually put 56hp to the wheels and 61ft/lbs of torque. This is not because it uses more nitrous, just has
a much more efficient nozzle design. The only part of the NX kit that is patented is the nozzle because it's so good that's what makes the whole kit come together.

If you want a ZEX kit be my guest I will install and it will be a little
cheaper, however if you want to go fast get an NX kit. A lot of people say this and that, but I seriously have been there done that and tell you from direct experience with my own car and other cars that NX is absolutely the safest fastest system. I could honestly say if you ran with a 75hp shot on ZEX then the next run switched to a NX kit it would knock 3/10's or better
off your time with the same rated HP jets."
