how safe is running nos thru a stock engine? like probly a 50 or 60 shot.. well to be more exact.. runnin a 50 shot of nos thru a b18b engine? anyone done it before? i wanna do it for a bit before i start with my new engine.. just to hav the ultimate "stock" gsi ;)
No not safe. No matter what engine it is or however its tuned. People do it, and go on about how good it is, until they post a thread up "my engine blew up" or "black smoke out of my exhaust, why?"
You reduce your engine life by alot, even if its tuned.
i've seen one person do it on a old old old R31 Skyline GTS... i think RB20?
neway he rebuilt the engine with good components, serviced it regularly, with sensible boost (i think 12psi) and 25HP nos more for the wank factor than nething else... he did drive it hard but wasnt to track or nething...
he NEEDED a rebuild (as in conrods were loose due to stressed bearings or something) after 80,000Km. thats 80K after full rebuild
hmmmm.....NOS??? fun but not worth the money and the headache unless you are in that business.....other wise if you have money to throw away than yeah why not??
nitrous in its most basic form is just an oxygen molecule combined with two nitrous molecules. It has no color or smell and will not harm the atmosphere in any way. When nitrous is introduced to the normal air and pressure that we breathe it turns into a gas.
Contrary to popular belief nitrous by itself will not make any power for an engine. All the nitrous does is give the engine more oxygen to burn fuel with, just like a turbo. When the nitrous hits the engine the additional oxygen helps to burn the fuel at a much faster rate, which in turn provides more power to drive a piston down faster in the piston chamber and thus creates more power. The key to the whole equation is fuel and how much power can be harnessed by the consumption of fuel. If this combination is not correct then it will lead to an uncontrolled bust of energy otherwise known as detonation inside the engine. When this happens one can expect to experience burnt pistons, blown rings, and thrown rods. Yes, not good at all!! This is where the problem lies with the bad reputation that nitrous has in the performance community.
ive got a vid clip of an NSX motor blowing on a dyno supposedly because it was running nos prior to the dyno tune/test.
why would u waste your money on it when u could put that money towards mods for your new engine??
and i hope u realise u cant use nos on the street?
the only condition that i would buy and use them is when i m playin some car games with PS2
it is safe in small amounts.
get a small 'dry' kit. fit it get it tuned and be happy.
lol
its perfectly fine to use if you have it set up right. Except that its illegal on the street
Poid's right.Quote:

This is the SAFEST way, and of course, you need to account for the additional O2 molecules by richening the mixture. In other words, Tune it!
reminds me of fast n furious!
so its just as safe to use as tuned turbo/supercharger set up??
if not tuned correctly a F/I motor will ping till somethings goes (hope its head gasket)
but if nitrous is tuned correctly its just as safe as a turbo setup?
maybe even more parctical as it can be switched off.
Not entirely True.Quote:

The (almost) instant power increase NOS provides is a stress to the motor,gearbox, etc.
k. but a 35 50 hp shot is toreble to a engine right its only when its a big shot that you cause damage
well basically i can get the nos kit pretty cheap.. around 600.. i cant use nos on the street anyway coz my license is suspended. i was planning to have it set up under the pedal and have it tuned professionally.
true that! agree with this dude!Quote:

actually N2O is a greenhosue gas and it does harm the atmosphereQuote:

Yes NOS is ok to use on a STD engine provided that it is used as PROECU said with a micro switch and only turned on with 100% throttle.But you need to retard the ignition timing by 2-4 degree's (this will change with different engines) when the NOS is on when using it on a STD engine.There are a few types of NOS systems around and if you want to run a 50hp shot just go and get yourself a ZEX kit and you can just retard the dizzy a couple of degree's of timing and then go and have some fun. :thumbsup:If you want the ultimate GSi setup go out and buy an ecu that can control NOS and tune it in correctly for the best result.One more thing how many guys that have replied to the original question have used NOS first hand not I read this and I heard that he has asked a question and all you guys do is just reply with answer's but yet you have never used it on your own car.There are a few reply's that are very good advice and very true but some are just speaking out of your arses.Quote:

its wired up into ur throttle sensor
I always use dry NOS setups for clients. Typically 50 or 75hp shoot on almost any standard engine is absolutely safe as long as its tuned correctly. For all my clients that iv tuned with NOS I make sure they all are using larger than stock injectors. The standard fuel pump is ok, but I also recommend this is replaced. 440cc size injectors are perfect for street NOS use. The kits I install are all dry kits with the nozzles / jets installed in each runner of the intake manifold. The car is perfectly tuned both mechanically and via in my case Hondata, for NA and then we tune with the NOS on top.
We have several levels of activation for the NOS, first is the tap on the bottle, this is the ultimate control of activation, the bottle is either on or off.
The 2nd level of activation is a toggle switch (with flip cover) mounted on the dash which works in to fold.
If the switch is switched on, and the bottle is physically tuned on the Hondata will control the amount of NOS injected, the amount of fuel to add and the amount of ignition retard.
Typically I set the following parameters,
Minimum engine speed RPM to activate
Minimum engine load to activate
Minimum throttle position TPS % to activate
Minimum vehicle speed to activate
Then for safety I also set the following parameters, typically killing the activation of NOS 850rpm before redline, using
Maximum engine speed RPM to turn off
Maximum engine load to turn off
Like wise if the toggle switch is off then you will have zero activation of NOS, no extra unwanted fuel delivered, and the car will drive as per normal. This gives a very quick and easy way for more power when you want it from a flick of a switch.
The other way to wire up NOS is like they do in fast n the furious ;) push the button and instant power, again when I do setups like this I still setup minimum and maximum limits, if the engine isn’t within the correct limits you won’t get activation. In summary NOS is great, if that’s the kinda modification you want to do.

stop quoting default values of the Hondata editor... LOL
lol goose there the parameters I use for my clients..
Fact is dry setup with ECU control and extra fuel from the injectors is the preferred way of setting up NOS
Actually if I’m quoting all the features we also have minimum intake air temperature control ;) also which I left off the list ;-) ehheeh but this can be annoying so its not used very often
Regards James

People still do it thow ;)
yeah but the fine is something absolutly stupid for nos being hooked up... as opposed to the couple of hundred $$ and potential loss of a few points for an aftermarket exhaust...Quote:

theres a guy running a 150shot of nos on a s2000 here in wa...saw the car at illegal drags but yea he managed to do about 4 runs with nos...car is still running fine to this day been over 6months since he installed that nos kit...i guess it all comes down to how lucky u are ahahahahah if ur lucky ur engine wont blow if ur unluckly den 1 shot will kill ur engine
isn't using nos on the streets a $5000 on the spot fine and car towed away in NSW?
i remember this was discussed before...
Nos = F&f
why spam a 1yo thread?
Hmm. Agreed = closed.Quote:
