first off.. i think NO² is the correct Chemical Formula for Nitous Oxide)

Is NO² good for you engine, i don´t wanna bust my engine, but i think a shot of nitrous would be nifty neato super duper... but i herd nasty things about it, what it can do to an engine, are these things true?

There are three points. First, nitrous oxide is comprised of 2 parts nitrogen and one part oxygen (36% oxygen by weight). So, it´s actually N2O, nuke... When the nitrous oxide is heated to approximately 572oF (on compression stroke), it breaks down and releases extra oxygen, but its not this oxygen alone which creates additional power, but the ability of this oxygen to burn more fuel. By burning more fuel, higher cylinder pressures are created and this is where most of the additional power is realized. Secondly, as pressurized nitrous oxide is injected into the intake manifold, it changes from a liquid to a gas (boils). This boiling affect reduces the temperature of the nitrous to a minus .127 Degrees F. This "cooling affect" in turn significantly reduces intake charge temperatures by approximately 60-75 Degrees F. This also helps create additional power. A general rule of thumb: For every 10 Degrees F. reduction in intake charge temperature, a 1% increase in power will be realized, which means that a 350 HP engine with an intake temperature drop of 70 Degrees F, would gain approximately 25 HP on the cooling affect alone. The third point, the nitrogen that was also released during the compression stroke performs an important role. Nitrogen acts to "buff or dampen" the increased cylinder pressures leading to a controlled combustion process.

Also nuke about what it could do to your engine: A kit that uses the correct factory calibration does not usually cause increased wear. Because the energy released in the cylinder increases so do the loads on the variuos components that must handle them. If the load increases exceed the ability of the component to handle them, added wear takes place. NOS kits are designed for use on demand and only at wide open throttle. Nitrous can be extremeny advantageous in that it is only used when you want it, not all the time. All NOS kits are designed for maximum power with reliability for a given application.

I didn´t read all of James post because I´m really really tired and just feel like talking. Yeah like the first line of James´ said, its N2O. NO2 or Nitrogen Dioxide would give you more of kick then you could imagine, due to having twice as much O2 as N2O per mole of the stuff.

but the real question, can N2O be dangerous for the motor....YES. Actually the biggest danger of N2O is fuel believe it or not. And the problem with fuel is not enough of it. When you pull the fuel back on a motor you can watch the EGTs skyrocket and hear the detonation. With N2O in the motor, you can observe it the same way but the stresses in the motor are ungodly. You would be amazed at how fast you could spin a rodbearing or just burn up your piston rings. Not to mention how on a lean burn with N2O could warp a head and just destroy exhaust valves. For an exhaust valve with the motor detonating with N2O in the mix...the valves pretty much look like that wonderful shot from T2 where Sara OConner has the dream and she´s just vaporizing from a nuclear blast.

Here´s the thing, be honest with yourself, How often do you think you would be squeezin´ it?!?! If you honestly think you´d be hitting the bottle on surface streets to get in front of a few more people when the lanes go from 2 to 1...N2O is NOT for you. If you plan on getting an awesome timeslip at the track and basically showing off your bottle at your weekend hangout with friends...well that´s a different story.

I came to the conclusion that I would be emptying a bottle too much, so I opted for just going turbo. However, now that I have the turbo in..sometime next summer I´d like to put my turboscort on the bottle at the track. But believe it or not I´m actually considering N2O or H2O injection to bring down my temps and cool my intake air temperature to make the forced induction more efficient. And a bottle just makes people think twice about giving you crap...whether its hooked up or not.

To each his own, just consider what type of cool is right for you.

My buddy has the ZEX system. He had it in his accord and his CRX. He never had the money to get it filled in his accord before he got it repoed and then he didn´t have the fittings to hook it up in the CRX. But he had the purge kit hooked up and he would blow that off and nobody knew it wasn´t hooked up to the engine. And no everyone would think twice when they found he had that. Anyways they say ZEX is safer than direct port and don´t wear your engine like direct port. So anyone know if that is ture or not? If you don´t know how ZEX works it´s shot through your intake and sucked in and you can only get about a 55 , 65 or 75 shot with it I belive. So if anyone knows the story with this stuff let me know. I was curious about it.

There are three ways to put N2O into your motor. Dry Shot, Wet Shot and Direct Port.

The most efficient is Direct port, because it goes straight into the cylinders. Wet shot means you tap it into the fuel lines and it goes in with the injectors and Dry shot means it goes into the intake....like a Zex kit and many others.

For kits like Zex you drill and tap your intake manifold and it goes right into the manifold after the throttlebody.

I have to get going to class, but here´s another thing to consider about N2O. "Shot" size is based on the power output of a Chevy 350 with an aluminum head. Now realize that a Chevy 350 has like 3.5x the displacement of our 1.8L and 1.9L motors. Unfortunately that makes our shot "weaker." So if your shooting a 50shot of N2O you´re only really getting about 22hp to the ground. However if you using a bigger motor like a Dodge 488ci V10, a 50shot would be like 60hp to the ground. Units suck, escpecially when they really have no meaning.

I hate dry kit´s. Wet all the way. The fogger sprays both nitous and fuel for a better mix and less chance of going lean. Both NOS and Nitrous Express sell nice wet kits. All so the one thing people always forget when running nitrous is you MUST RETARD TIMMING! Also Jacob´s electronics sells a nice nitrous master mind so you can retard your timming and even stage your nitrous. We setup and used properly it won´t add extra wear on the motor. You will need a stronger clutch because the factory won´t last that long on the new found HP.

Yeah, the -only- nice part about going dry is you can use it to pre-spool the turbo at the track.

I guess if your going to do it all the ´right´ way with a boosted car, you´d use a really small motorcycle type shot dry to spool the turbo and cool the intake charge, then use a wet shot thats closely controlled at WOT conditions to truly use the N2O for oxidizing the fuel. I´ve noticed when I shift I can actually shift quick enough to shorten my blow-off to nearly nothing, so you´d only need a little motorcycle type shot for the holeshot, and that´s about it.

I had a 55 shot of N2O (Zex) on my ´scort for a while. In 1st gear it really made a nice difference, 2nd a bit too, but in 3rd or 4th I couldn´t feel the effect nearly as much, almost to the point of couldn´t barely tell. This was on a nice full bottle nice and warm as well.
I saw a ´96 prelude VTEC on the dyno with a zex kit. He had it jetted for 55 hp and it made 50hp more AT THE WHEELS across the entire run. FYI zex is just a dry shot of N2o with a little gimmic that used nitrous pressure to up the fuel pressure through the stock FPR. Before I had the ´scort I put the zex kit on my ´89 mazda turbo. With the 55 hp jets it made dyno proven 80+ ft lbs of torque and over 60+ hp to the wheels. So it really depends on the car as to how much hp n2o will add. I never wanted to waste $50 to run the escort on the dyno but I wish I had to see what it would have put down.

Hey, how did you like that Zex kit. I too was considering the purple haze. Seems like in my town everyone is a follower so everyone runs Nitrous Express. I haven´t really heard anything great about them though. I know NOS is pretty basic, but makes a ford specific set up. Venom makes a great kit from what I´ve been told, but you pay for it.

My knowledge base could use alot of help understanding the specifics of nitrous and running it safely. What would you recommend for my boosted Escort ? What do you think the easiest install would be?

I guess just tell me what you would do in my case. With the 460cc injectors, I know that even at 14psi I should be able to flood the motor if the pump could keep up with them, so my plan was to have enough extra fuel on tap for some N2O.

Blade I would spend the money on the Venom setup. I have been going over the options and the Venom setup is worth it, especially with the time and money you already have invested. As far as I know it is the only kit that is totally adjustable. I have yet to hear anyone rave about the ZEX setups. just my two bits.

I agree if you´re going to do something I should do it right. But the difference in cost is about 800 bucks.

Well said though. I guess one of the big visual draws to the Zex set up is the toggle switch. I like the idea of a toggle switch and not a push button, but I guess that´s mostely implementation.

The reason why they are using nitrous express is because it is the best.. zex is shit, sorry to say. Venom is OK but if you are basing your decision on the fact that they have a quick drag car, then it should be pointed out that it has a direct port setup, and uhhh venom doesn´t sell a direct port setup??? lol... NOS is another OK brand... your mostly paying for the name brand. FYI adam it is illegal to have a nitrous kit on a vehicle in saskatchewan, unless it is ventilated... Are you going to cut a big hole in the back of your car? I didn´t think so, lol... Don´t say that the cops won´t enforce it either cause they will, as I was talking to sholte(cop) about it and he said "don´t waste yours, or our time, because we will confiscate it and give you a large fine..."

exactly how would a cop know unless you put a NOS sticker on your ride? the law in sask can suck on my tailpipe :)
Does that mean if i have a NOS system on my car I can´t drive through Sask and if I do and get stopped they could confescate it?
