View Full Version : Nitrous In Everyday Life??
Cobalt5533 11-12-2006, 07:17 PM ok,
so i have been interested in nitrous for quite a while now, and am now almost ready to get it for myself, however i still have one thing to clarify : i do not want to f*ck anything up so am going to run 2 step colder plugs and most likely pull timing one degree along with keeping a bottle of octane booster with me at all times ( as in quebec the higher octane we got is like 91) but i just wonder : will plugs and timing change the way the car acts in everyday life ( as i would not spray so often ) and could it possibly have any issues ( even a tiny little mini one ) or any prematurate wear ???
Cobalt5533 11-12-2006, 07:53 PM edit : oh and also i often hear about not to hold the juice for too long ... so how long is too long ??? lol like can i row it through all gears but the 1st or i should just go in 2-3 ??
i am probably going with NOS has anyone an unbiased oppinion on it ???

Cobalt5533 11-12-2006, 08:53 PM euhm... alright... good guys... how about trying to answer my questions ?????
joeworkstoohard 11-12-2006, 09:02 PM okay... yes, adjusting timing and colder plugs will affect it, not in a good way... note, the timing on these cars is automatic, leave it be.
as far as "long time" you only really need to worry about it if you're going to hit the fuel cutoff or start way overheating the engine, trust me, 10 seconds on the squeeze is a LOOONG time.
invest in a good window switch, and a nice basic wet kit, you shouldn't have issues.
HackAbuse 11-12-2006, 09:05 PM Will people have problems with two-step colder plugs on a daily driver?
tonylee232 11-12-2006, 09:07 PM about 10 to 15 sec is good the longer it is bad...
joeworkstoohard 11-12-2006, 09:14 PM Will people have problems with two-step colder plugs on a daily driver?
that depends, i'm guessing that he will be changing out his plugs pretty often if he's running colder ones.
Cobalt5533 11-12-2006, 10:22 PM why??
aj_92rs 11-12-2006, 10:37 PM that depends, i'm guessing that he will be changing out his plugs pretty often if he's running colder ones.
That's correct.
Colder plugs don't burn off the excess fuel as well as hotter plugs. Plus they don't help for efficiency. The hotter a metal is, the easier it conducts electricity. You always want to run the hottest plugs you can without detonation.
BTW, I know the ceramic is what dictates how "hot" a plug is, but the ceramic transfers the heat from the tip. The tip is what you want to stay as hot as possible.
Your MPG my go down slightly from running colder plugs due to them being less efficient.
Please go with a wet flow kit. Dry flow kits are for guys that like to live on the edge. I'd never trust a dry flow kit. They just seem way too risky to me.
You don't need to worry about a rev limiter, but what you do want to worry about is a RPM switch on the nitrous. Our engines limit RPMs by cutting off fuel to the engine. Cut off the fuel and the nitrous WILL destroy the engine. It will cause a nasty lean mixture which will burn extremely hot and melt hole(s) in a piston or four. You want the RPM switch to cut off the nitrous before the stock rev limiter kicks in.
The other option is a fuel pressure switch. It's a switch that cuts off the nitrous below a certain fuel pressure. Honestly, the only ones I've seen are for carb applications and don't cut off the nitrous until the fuel pressure gets below 5 psi. That's way too low for an EFI system. Maybe they're made for higher PSI applications? I honestly don't know.
I haven't used nitrous on any of my personal cars, but have a few friends that have/do. I've only learned what I know from them. And we're talking 9 and 10 second cars, so I'm sure they know what they're doing. ;)
Cobalt5533 11-12-2006, 10:43 PM alright, doesn't seems too bad for me ... i could live with that.. however i was totally sure of going with NOS but i just checked in depth venom kits and i really like the computer controlled kit ... anny thoughts on that one ? or i should just stick with Nos ??????
aj_92rs 11-12-2006, 10:45 PM Zex also has computer controlled systems, but they seem to be geared more for dry kits, which I already gave my feelings on.
aj_92rs 11-12-2006, 10:48 PM HEHE.... :D

IonNinja 11-13-2006, 10:11 AM i hate the way my car feels N/A with these 2 step colder NGK plugs but thats just me...

Like it or hate it...you cannot deny the fact that that movie put tuning on the map far beyond what it used to be. and the simple fact is, cars like the SRT4, Cobalt ss/sc, Mazdaspeed3, and all of the aftermarket that we find for them....were probably brought out, and strongly influenced by the effect that movie made on youth subculture.
Sorry....but I actually really enjoyed that movie when it first came out (yes i understand now how funny it is in heinsight)....I was young and had no huge knowledge of the tuner world....but I like many people who dont like to admit it, started liking fast cars around the time that movie came out.
Fatalis 11-14-2006, 06:56 PM Colder plugs run fine. Ive been running on them forever, i did a roadtrip with them in, and got 4500 with no problems. I averaged 35 mpg on that trip.
91 octane is fine too.
any questions, ask.

Oh and btw, NOS is a good choice. NX is also really good, so consider them both, but you cant go wrong with NOS.

actually i know it seems really stupid and im gonna get flamed for this but i just like nos cause of the stickers and of the bottle.. id go with zex but the pinkness will just punch me in the face everytime ill see it

LOL :lol:
I'm not 100% sure, but you can probably buy the controller without buying the kit.
1fstss 11-14-2006, 11:17 PM lets clear up some facts here, as long as your only spraying like a 50-55 shot you will be fine with 1 step colder. i was running stock plugs on a 50 shot and when i pulled them they looked perfect. a 10 lb bottle on a 100 shot lasts roughly 2 minutes of on the bottle time. a dry kit is not bad or "unsafe" a dry kit just relys on your injectors to deliver the fuel, where as a wet kit you are injecting the fuel ontop of the injectors. all straight nitrous will do is stall your motor. it wont cause catastrofic failure. with a wet kit you stand the chance of fuel puddling up in your intake and when it catches up KABOOM, its not a common scenereo though so dont worry. if you have a supercharged model, use a wet kit, if you have a N/A car id suggest a dry kit. a dry kit is perfectly safe, and is easier to hook up. i would also recomend a zex kit, if you dont like the color paint the box :lol:
your drivability while off the bottle will be damn near unchanged.
oh and I my self have 3 cars on spray currently.
97 Camaro SS on a 150 dry
95 Z28 on a 2 stage 300 shot wet
and my cobalt SS/SC on a 75 wet
ive installed atleast 15 kits that i can think of off the top of my head, so ive been around the block.
HackAbuse 11-14-2006, 11:20 PM I would never use a dry kit
HackAbuse 11-14-2006, 11:21 PM btw, I know someone that's running a 75 wet shot on stock plugs and 87 octane without problems, do you think I could get away with 1 step colder and 91octane on a 75 shot?
e to the x 11-14-2006, 11:55 PM The hotter a metal is, the easier it conducts electricity.
Other way around. Higher temps decrease electrical conductivity. Molecules spread out as temperature goes up so the electrical path becomes more difficult to traverse.
Fatalis 11-15-2006, 02:21 AM The electric conductivity of an element depends on what it is. Some get more resistance as temps go up, and some drop as temps go up. Depends on what the plug tip is made of.
I would use a wet kit for NA applications on the 2.2 and 2.4.
I dont have issues with with fouling my plugs runnining NA.
You may hear little popping and grumbling, but Overall it doesnt affect Daily driving whatsoever. Even, so its a good idea to change plugs after running with nitrous. I personally go through a couple bottles and change out my plugs. It costs like 12 bucks, so its no big deal, and better safe than sorry.
1fstss 11-15-2006, 10:41 AM your friend is stupid if hes running 89 octane and stock plugs on a 75 shot. but like i said, a dry kit to me is alot more safe than a wet kit, the only reason you use a wet kit with forced induction is because your fuel pressure regulator is already climbing at a 1:1 ratio under boost. with a NA car thats damn near stock, i almost always recomend a dry kit, worse case scenereo is you lock up an injector, and if that happens, it means your lazy and modding in the wrong direction. if you want to half ass the nitrous kit thats fine, just have a video camera rolling all the time so we can see you blow the hood off your car ;) (ive seen it happen, its very entertaining for the spectators, not the owner ;))
aj_92rs 11-15-2006, 02:42 PM 1fstss, I think you have it backwards.
A lean fire on a dry kit can cause extreme heat in the cylinder. A wet kit minimizes (I don't want to say eliminate, because anything can happen) the chances of that happening.
If an injector were to lock up, residual fuel in the intake runner and/or plenum can still find it's way into the cylinder. If these were direct injection engines then what you're saying would be true. But they aren't. A lean condition can cause a lot of problems whether the engine is on the bottle or not. But being on the bottle just intesifies the effects.
A wet kit is simply safer to use.
Here are two quotes from two different nitrous oxide companies. Click on the quotes to go to the websites.
QUESTION Will nitrous oxide cause detonation?
ANSWER Not directly. Detonation is the result of too little fuel present during combustion (lean) or too low of an octane of fuel. Too much ignition advance also causes detonation. In general, most of our kits engineered for stock type engines will work well with premium type fuels and minimal decreases of ignition timing. In racing application where higher compression ratios are used, resulting in higher cylinder pressures, a higher fuel octane must be used as well as more ignition retard. (http://holley.com/TechService/FAQ.asp?category=NOS)
Q: What is the difference between a "wet" nitrous kit and a "dry" nitrous kit?
A: A wet nitrous kit mixes nitrous and enrichment fuel by means of an injector nozzle that is mounted before the throttle body. This mixture is then drawn into the engine through the throttle body and intake manifold. A "dry" nitrous kit injects only nitrous with it’s injector while at the same time, increasing the engine’s fuel rail pressure to feed enrichment fuel through the engine’s own injectors.
Q: What is better, a "wet" or "dry" kit?
A: It all depends on the application. A "wet" kit is ideal for both normally aspirated applications as well as forced induction applications. It can require a little bit more installation time than a "dry" kit, but is easier to tune if greater than stock HP settings are to be experimented with. A "dry" kit is excellent for normally aspirated combinations that have a return style fuel system. They are very easy to install and are a great "first time" nitrous system. It is not recommended that "dry" systems be used on forced induction engines. (http://zex.com/Products/FAQ.asp)
joeworkstoohard 11-15-2006, 02:49 PM from what i understand, the wet kits arn't that bad on the balt... as i gather, there is a plug or fitting on the end of the fuel rail that you can tap into.
perhaps someone can offer more light on this, but that's what i recall seeing.
ideally, with n2o, you want it to be as automatic as possible. in other words, you just want to arm it, mash the pedal and go.
aj_92rs 11-15-2006, 03:01 PM from what i understand, the wet kits arn't that bad on the balt... as i gather, there is a plug or fitting on the end of the fuel rail that you can tap into.
Probably is, as most fuel injected cars have a Schrader valve on the end of the fuel rail.
A Schrader valve is the same type of valve that's used on valve stems for tires.

yeah, i assume for testing pressure. following that logic, you'd just need to unscrew it, get some sort of fitting tomake the fuel line for the wet kit fit, and "Viola" you're cooking with gas.
aj_92rs 11-15-2006, 03:44 PM "Viola" you're cooking with gas.
No pun intended? ;)
joeworkstoohard 11-15-2006, 07:21 PM No pun intended? ;)
no, none at all. honestly, i've thought about going the n2o route, but i'm all about the 35-50 shot... just enough fog to make the car edge out cars that should beat you, or destroy ones that are normally runners.
i have an old friend with an Si that hits the giggle gas to shut down Tc's. i don't understand why, it's needless... now aganst my car which would be a run, i could understand because it's the nail in the coffin.
with nitrous, start small, work up.
oh, the reason a dry kit with a balt is dangerous is because the fuel system is returnless, most people would add a fuel pressure regulator to their return line that would increase pressure, so that with each open it would spray more fuel. this doesn't work near as well with a returnless setup.
1fstss 11-15-2006, 10:25 PM i have my fuel tapped off the shrader valve, a -4an line fits right on it ;) i used a semi valve stem remover to get it out :)
Cobalt5533 11-16-2006, 12:56 AM quick question : i know if you route a pressure gauge to the dash you'll loose the nitrous in the line to the gauge but what about the electrical ones ???
Fatalis 11-16-2006, 01:51 PM Electrical ones i assume just read from the bottle, and send the pressure via digital signal. however... they ARE HELLA expensive. Compared to a normal guage anyways. Very fancy though. Buy me one for christmas lol.
Wet kits are not dangerous or unsafe at all. You wont puddle if youve installed the nozzle correctly, and its much safer than the dry kit on our cars. If one solenoids fails, if you have it wired correctly, both solenoids will not be grounded, which means they both will shut down to prevent the nitrous solenoid from just spraying.
Id rather puddle and blow off my intake than run lean and blow up my engine and melt pistons. My install is perfect though, so im not worried about any problems.
Fstss has the schrader valve right. Its a nifty little test port that the nitrous companies utilized very cleverly. you jsut pop taht fuel line right on. Beats having to splice into it.
aj_92rs 11-16-2006, 02:53 PM Other way around. Higher temps decrease electrical conductivity. Molecules spread out as temperature goes up so the electrical path becomes more difficult to traverse.
Maybe that's it. When it heats up it takes more voltage to jump the arc across, which dilutes the spark.
It's something like that. Either way, there are answers on those links I posted. ;)
slowion2 11-17-2006, 12:11 PM fatalis and don and aj covered about most of it.
just wanted to add, I would go dry if I was sticking with a 50 shot or less BEFORE the maf, any higher and I'd go with a wet shot after the maf.
I've fun 2 step colder plugs for a while now, I change them out once every 6-9 months but this last set has been in a while now with no problems. I'll probably swap them out soon though just for piece of mind before a coming track event.
if you have questions you can PM me, I'm not going to read through all this since most is covered I'm sure.
IonNinja 11-17-2006, 11:36 PM so what other plug options are there anyway besides the 2 step colder NGK plugs?
chevysalesman614 11-29-2006, 02:43 PM actually i know it seems really stupid and im gonna get flamed for this but i just like nos cause of the stickers and of the bottle.. id go with zex but the pinkness will just punch me in the face everytime ill see it
Every straight man is supposed to love pink! what is wrong with you?:lol:
BTW the zex bottle is purple.. you're colorblind my friend
06Pursuit 11-29-2006, 02:54 PM make sure to pickup the F&F NOS nitrous kit with the included led NAAAAUUS!!!! switch lmao!!!
