Someone explain nos

Is it just me or is Nos dumb and over rated I understand it somewhat but would like to know more even though I don't think I would ever use it here are some questions
1 I know there is wet kits and dry are either safe or will they both destroy your car
2 why is it always introduced directly at the manifold why not say at the far end of your fmic
3 why should someone use it in the first place
4 what are must have mods if using it other then that two handed big red button that says kill my engine
Lol sorry I'm just sick of little gangsters asking if I have Nos and would like to have a good explanation for them

OK I understand and have already heard all the jazz in your link so many spelling errors looks like the people that are doing it are all pro Nos they do mention the blowing up your engine

Nitrous is good. Nitrous does not blow up your engine. It can contribute to an engine failure when combined with stupidity or poor judgement. Like anything else, it is in the hands of the user whether it is good or bad. A well setup and thought out nitrous system is likely safer for your car than a turbokit etc.
The only thing that sucks about nitrous is when you run out of horsepower and have to refill the bottle.

Edit, and yeah its just you, nitrous is not dumb nor is it overrated.

1> either kit is a pocketful of win. Used by a dumbass the same results will occur.
2> you can introduce it anywhere you like, but smart people use the method best suited to thier application
3>because it is relatively cheap, easy horsepower and can be hidden, if you want, so that few will know you have what you have.
4>the required mod is the kit and some common sense. Unfortunately, no one can sell you common sense, so you might be out of luck.

i thought nos was a company..


ah yes, here it is.

Nitrous Oxide Systems (NOS)


or are you speaking of nitrous oxide?

It is used as an oxidizer in rocketry and in motor racing to increase the power output of engines. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen.

colder condensed air means you can cram more air into the engine, including fuel. this is basically like increasing your compression ratio dramatically with the push of a button without all the drama that comes with actually increasing the compression ratio of the engine.

wet kits are usually deemed superior because it is more finely tuned and adjusts with how much fuel you are pushing to the engine. dry kits introduce the dense air first then it is up to the engine management to make the proper adjustments which is why many dry kits result in many more blown engines with poorly done tunes.

to be safe you need to compensate for the nitrous with more fuel, so an engine management system is basically a must if you want your engine to last.

nitrous has it's place, for people who don't want to spend thousands on a turbo or supercharger. many racers also use it as a supplement to run a larger turbo than the engine would naturally be able to handle, pushing the horsepower limits even higher.

most of the ricers asking you the question wouldn't even understand these explanations anyways so... if someone asks me i give some obligatory answer like "yes, i have it pumped into my exhaust to recirculate the oxygen through my recirculation valve which runs back through the engine so that the exhaust velocity increases the volumetric efficiency of the engine", which of course is some random bullshit.

n2o isnt really cold condensed air though and works pretty **** poor as a power adder if its under a certain temp that is at least room temperature. its an oxidizer. engines are basically oxygen pumps. increase oxygen and you will increase power and with the correct a:f ratio you can do it without blowing things up.

nitrates, nitrites are relatively powerful oxidizers, thats why its possible to blow stuff up with fertilizer etc.. but introducing any chemical compound oxidizer will net in performance increases. im sure they all have different burn rates though and n2o happens to be the most stable for ICE performance.

the archive is the best place to find knowledge, i think it goes over what most people here have already said but it has a little more and is very helpful, it should answer any and all questions you have, or will have..

n.o.s. brand was sold to Holley back in the 90s, I use to get product sponsorship before selling out.

When I ran nitrous oxide back then, I was able to drop over 2 seconds from 1/4 mile time and gain over 20 mph on early 4-port standard bridge port. It was only a 150 shot.

Impressive! What chassis and transmission was this with? Engine aside, did you have trouble breaking driveline parts?

2300lbs rx3 with driver, old school 4 port bp, 8.8 rear end with 1rst gen transmission, never had transmission issues. best time in back in 96 was 11.17 @ 121 granny shifting, probably could off gone 10s but decided to go turbo and never looked back.

OPs first post sounds more like he is asking what he needs to use it. in a roundabout kind of way.
