Hey, im thinking about gettting a Nitrous set up and was wondering whats the better set up? I want to get a DRY set up becuase it looks to be easyer to install. But wahts the benefits of wet vs dry? and what would you recommend.

thanks

 

I also am thinking about putting a dry systems on my 98 Max. I am not new to the Nitrous game, but just weary since I know that I always want to go bigger & bigger with the amount of juice I'm spraying. I would suggest going with a dry system since our vehicles are a dry manifold design. That means that our intakes are designed to only flow air, not air & fuel. Thats not to say that you can't use a wet system on a dry manifold design. You just have to be causious of a couple of things like notrous explosions. When ever you run a wet system on a dry manifold design you run the risk of having a backfire. This can cause several problems. blown seals, broken check valves & in extreme situations you can actually blow the manifold right into the hood. If you do go with a wet system on your dry manifold engine then go with a direct port set up. If you are new to the NOS game then I would just get a DRY system. This is the safest route & as a beginner it can teach you a lot. I highly suggest getting a book on Nitrous "All you need to know about Nitrous". And read very carfully. It will teach you about fuel management, computer control & most importantly safety. I am probably gonna start out with a 20hp shot with my dry system, see what kind of readings my Air/Fuel gauges give me & adjust from there. Remember to purchase an adjustable fuel pressure regulator so you can increase fuel pressure at your injectors. Also, sometimes it's better to adjust your fuel pressure then to adjust your nitrous jet size. Learn to read you air/fuel ratio gauge. Get the book, it will help you understand nitrous better. And it will help you decipher good advise from bad advise...

 

i was worried about the fuel mixture when i was first reading about getting nitrous. I am new to this and tuning for nitrous. I was looking at the ZEX dry nitrous set ups. it was saying tht it uses a fuel pressure line to adjust the right amout to give when nitrous is shot in. Would ZEX be a good setup to get as a begginer becuase of this feature?

thanks

 

I was just reading about the ZEX kit last night. I have heard about them before, but I never really research them until last night. From my knowledge of using nitrous I can say that this kit is probably the simplest kit to hook up & use. Which is a good thing? However you will not really be able to upgrade this kit (mulitple stages & such), but I would highly recommend this kit. It is dummy proof & will give you gains that are very noticable. I would not recommend using the 125hp shot they say you can without other mods like upgraded fuel pump & bigger fuel injectors, internal engine build up. Even with those upgrades I would still be wery about using that big of a shot. The 55hp shot will be plenty & you will deffinitly notice a power increase! Just make sure not to use it under 3,000rpm & never, I repeat never use it when your in the vehicles tallest gear (auto 4th / manuel 5th) The race will probably already be over before you get to that gear anyway....

 

I'm pretty sure that the ZEX dry kit doesn't even require you to tamper with any of the fuel lines. I pretty sure all you do is hook up there wire to your throttle position sensor & a vacuum line from your stock fuel pressure regulator to there control box. You can find installtion instructions on www.zex.com

 

All kits that have a fuel pressure safety switch (good idea) require you to connect into the fuel line.

All wet and dry kits take basically the same amount of work and knowledge to install.

Personally I prefer wet, I have had both and installed both. I believe the wet is safer for the engine overall and not turning is required at all.

Don't believe the hype that NOS preaches about nitrous backfire, that was because up until they copied the NX nozzle design they didn't have a wet system that wouldn't backfire.

Dry systems get all their fuel through the injectors and if you ever have an injector plug or partially plug your cylinder is toast while spraying.

With a wet system the fuel is injected into the intake so the correct amount of nitrous/fuel is injected at all times regardless of what the injectors are doing.

 

so it sounds safer to run a wet set up? the only thing that was drawing me away from wet was, how hard is it to tap into the gas line? that was the only thing that scared me was messing around with the fuel lines. how hard is it to do this on a 4th gen max?

thanks

 

Most nitrous manufacturers recommend a fuel pressure safety switch (I do too) which shuts down the system if you lose fuel pressure.

In order to install this safety switch you have to tee into the fuel line anyway so you only have to connect the wet solenoid to to that tee.

The fuel line is rubber, all you have to do is relieve the pressure, cut the line, install the tee and connect it back together.

 

ok thanks for all the help!!! very much appretiated

 

this might be a dumb question but how do i relieve teh fuel line pressure???

thanks

 

Pull the fuse under the dash for the fuel pump and start the car till it quits (very quick) and then try starting a couple of more times to make sure.

You will still get some fuel when you cut the line but the pressure will be gone and won't spray you.

 

What you want to do is...
1st) Pull the fuse for your fuel pump.
2nd) Start your car & let it run until it uses all the fuel in the line.
3rd) Now you can disconnect the fuel lines. Just make sure to put a rag under the lines to absorb any fuel that might leak out...

Hope that helps you!!!!!!!!!!!

 

hey thanks for all the help, this helps alot!!!

 

wetter is better!

 

Is there an echo in here?

 

No, theres not an echo! Must have been typing mine @ the same time as you?

 

IT was 4 hours later, you must be a slow typist.
