Hey I was watching "rev it up" or "tuner vision", well something like that and they put a ZEX dry 50 shot on a Civic and got like 35 wheel HP. After seeing how easy it is it install, I'd think it would be even easier to uninstall (warrenty baby). So i was wondering if anyone has nitrous and seeing where they got it, what kind of system they have and seeing how much it set you back. Also if any other systems may work better? Any info would be great. Thanx

hey i did a search and got a million topics out of a one word search.....

 

I'll be conected a SWEET Nitrous Package for SCIONS soon...

Need a tC and an xA for test fittings.....

Got an xB lined up.

This will be for one of the industries best Notrious delivery systems made.
Reputable company and will be an exclusive kit for Scion.

Stay tuned or PM me.

 

i have a guy friend that keeps trying to get me to put this stuff on my car. what exactly does it do and what is it for?

 

Nitrous Oxide is used to give a burst of power at the touch of a button, or switch, or something (it can be set up differently).

 

please keep us updated.

 

If I'm not mistaken, nitrous oxide if kind of like an oxygen enricher. It enters as a liquid and because of the heat from your engine, almost instantly goes into it's gasseous state. It's adding more "air" into your chamber to be combusted.

Unlike turbos that constantly spool and force air in / supercharger do the same - Nitrous is kept within the lines until you release it into your combustion chambers.

Setups vary, but the two that pop into mind could be a "push button" type set-up where you physically have to press a button to activate the release of nitrous;

Or a "full-throttle" setup, where nitrous will be released when you stomp on the pedal, and the accelerator hits the switch on the floor once fully depressed.

Either way, nitrous is seen as "instant horsepower" or "horsepower in a bottle" it's good for a quick bust of extra go. A "50-shot" I believe would be tuned to give you an extra and instantaneous 50 horse power with a push of a button.

I'm also under the impression that it's not a good idea to constantly "spray" as it adds undue stress to your engine.

Corrections?

 

Nos doesn't neccesarily "sit" in your fuel lines, it is connected to them but doesn't enter the fuel line untill you start spraying. Wide Open Throttle switches are used almost 100% the time it seems, just in conjunction with a series of switches and/or what-not.

Its just as bad to "spray" a lot as it is to put on an aggressive turbo.

It is designed to get more oxygen into the cylinders. It does change when it gets there due to the engine's extreme heat. Nos(N20...two nitrogens, one oxygen) isn't flammable because the nitrogens stabalize the oxygen (which would normaly be very flmmable an unstable) in the molecular compounds, but when it gets into the engine, the heat breaks apart the compound an releases the oxygen.

 

Also:
Wet and dry applications...

As far as I know, wet applications have the Nitrous plumbed directly to the manifold via each cylinder's injector?

And dry would be plumbed to the intake tract, drawn through the throttle body, and distributed to each cylinder via the intake manifold?

Is that right?

 

Pretty much right, the Wet kit doesn't connect directly to the injectors, it mixes with the fuel before there. A dry kit does basically what your saying except its worth noting that it gets unevenly distributed to the cylinders, more will end up in some than others. A wet kit guarrantees equal distribution.

 

First off, Nitrous systems DO NOT use your fuel lines to deliver N2O to your Cylenders. The nitrous is fed through it's own plumming (usually Steel braided hose) from the bottle to the intake. Dry system refers to a system that delivers only nitrous and lets the ECU compensate for the extra fuel needed. Wet systems refer to a set up which injects fuel at the same time as the nitrous. Another thing, a "50 shot" Almost never adds 50 HP, on dyno tests it usually adds 37 or so hp. as for how long and when Nitrous can be injected, it MUST be over 2000 rmps, and under full throttle only. A few systems have nitrous computers that open different valves at different RPMs (still under full throttle only) which allow for a big nitrous punch in the beginning to comensate for the turbo lag of a real big turbo, or a small nitrous feed at low RMPs to allow you to "hook up" better off the line and a bigger jet once the rmps are higher. also you should only use nitrous for no more than 10-15 continuous seconds. I hope I covered everything. Most modern nitrous systems today are cheap ($500 or so for a dry system) and very reliable when used in moderation (no 100 shots for a stock xB).
Nitrous is an oxidiser and adds HP 2 main ways, 1. increasing the O2 content in the combustion chamber (it contains 150% Oxagen by volume versus air) and 2. it cools the intake charge (using boyles law... basically a gas at 500 psi will be cooler when introduced into a lower pressure enviroment [14.7 psi]) I hope this covers everything. If you have any more questions I'd be happy to answer them.

 

Er well I thought/was pretty sure that wet kits injected the Nit. directly into the fuel line through a nozzle that atomizes the fuel an nit. prefectly so each cylinder gets the same/best mixture

I'm positive the dry systems don't so thats fine but I'm really like reaalllyyy sure that wet kits inject it into the fuel line. Maybe if we can get a 3rd opinion, or I could look it up...I'll do that later.

 

I thought NOS actually had an adapter kit that mounts to/in conjunction with your injectors. That way they can be easily removed, plumbing included. Nothing hard wired into your manifold.

As for sitting in the Fuel Lines. I never said that. Re-read my post. Under the assumption that Nitrous is contained in a bottle, there must be something to move the nitrous from the bottle to the manifold, and that is what I was referring to when I said that "it" sits in the "lines" until you push the button.

 

Hey guys, great views and postings.

The kit I'll be promoting is computer controlled for safety.
Special safety features insure proper air/fuel mixture or the injection of nitrous is shutdown before catastrophic engine failure.
With closed loop fuel operation utilizing two dual processors to control the nitrous module.
It is the worlds most advanced nitrous system to date.


It's a lot of fun too!

If you have a supercharger, it can be plumbed directly into that.
Otherwise it's plumbed into the Intake near the throttlebody. (In certain applications)
We will be testing the Scions for applications.

I am hoping to have good news for everyone as early as mid-late October.
Of course I'll try to keep everyone up to date with any news.

Also, if Nitrous scares you, you can try C02 sprayers.
Used to cool the air, sort of like "Granny NOS".

 

I'm curious as to how the CO2 System works... you couldn't inject it into the cylinders, as it would displace the oxagen... is it used in a intercooler? If so is it a closed circuit or does it vent to the atmosphere? and if it vents, where would you vent it, if you did it in the enjine bay it would get in the intake.

 

I don't think CO2 can go into the engine...it is used to chill the the intercooler to reduce air inlet temperatures dramatically...or can be used as a purge kit to give the impression that you are running nitrous when in reality, you are not.

 

In that case, sign me up!

 

Did we kinda get off topic? Or is this still relevent?

 

A dry system uses the stock fuel pump to increase flow through the fuel injecters when you actuate the nitrous...

the wet system has a pressurized fuel line to add fuel and nitrous together into the intake...the nozzle will look like a "Y" with one line for fuel and the other for nitrous.

Some hardcore guys run individual jets into each intake runner close to the fuel injecter, but nitrous will never enter into the fuel line as stated above.

I use a carb spray plate on my old school Mustang (I'm a mullethead)...

With the Stang crowd the dry is the easiest route with less danger...but the wet is worth more power on a built smallblock. You run the danger of pooling fuel in the intake with the wet kit which can lead to some amazing hood popping backfires...

For the xB I will be goin with a dry kit as it's the wifes car and it she just wants to have a lil fun. The Zex kits look promising, but I have to admit I'm more of a smallblock guy than into imports so I'll need to look into it a lil more. So long as you don't lean out the mixture yer pretty safe, and the Zex are computer controlled and should watch out for that.

A 50 shot should surprise quite a few cars on the street. Maybe even shut down a couple of my V8 buddies that rag on me for gettin a Scion. Not likely beat em, but shut em the hell up.

Why is the nitrous guy not answerin these basic questions?
