iv heard addin a shot of 50 or so of nos is fine for a stock motor im interested in what you guys think of nos is it good or bad

 

Sounds to me like you've seen the movie The Fast and the Furious. Don't believe everything you see in a movie. The stuff isn't called nos. NOS is a Holley performance brand trademark, used to describe the PARTS you can buy to inject NITROUS OXIDE into your engine for a performance gain. The gas is abbreviated by using N2O, or calling it nitrous, or many other slang terms. I spend a LOT of time with other racers, and have NEVER heard it calle "nos".
Now that I've gotten that off my chest, I'll answer the question.
Nitrous Oxide works by adding more oxygen into the intake charge of your engine. It also helps cool down the intake charge. It does NOT burn on it's own, and neither is it by itself explosive or flammable. If you add more oxygen into the intake of your engine, you also have to add more fuel (gas). If you don't, your engine will run lean, and your pistons will melt (at the very least). Some computer controlled engines with fuel injection can be run safely with a small shot of nitrous. The oxygen sensor senses the increased oxygen in the exhaust, and the computer adds more fuel to compensate to keep your engine from running lean. This only works to a certain point, because your stock fuel system can't add enough extra fuel to keep your engine from going into meltdown. I myself would not run any amount of nitrous unless I had forged pistons, and an upgraded fuel system. Something else to consider, is that a bottle of nitrous does not last very long. It's also pretty expensive to get them refilled. Superchargers and turbos are where it's at, but then again, your engine has to be built right for it to last.

 

WOW, I can't beleive you actually heard him say "nos" through the reader board. I took it as N.O.S. meaning Nitrous Oxide System.

 

Isn't NOS a brand of nitrous oxide injection?

 

NOS? Oo, a New Old Stock! Is it a 2150?

 

i would never run "nos" in any car or truck engine. one it's really expensive and 2 it's a cheat. you buy it if your car is too slow to race.

and real life isn't like the fast and the furious bud.

my own opinion nos aint woth it. but that's my own opinion

"iv heard addin a shot of 50 or so of nos is fine for a stock motor im interested in what you guys think of nos is it good or bad"


The way it is written kinda sounds like he is saying noss not N.O.S.
Too much Fast and Furious I guess

Now, my personal thoughts on nitrous. I pesonally wouldn't use it in a stock engine. The ring end gaps should be wider and you should use forged pistons, even with only a 50hp nitrous system. I wouldn't take the chance of blowing the engine up for 50hp. I am not an expert on this by no means, just my thoughts.

 

well i said nos meaning nitrious oxide system i know holly owns a company called nos and i didnt mean that i just ment n2o or heck call it funny gas i just wanted to know what you guys thought of it iv heard mix some say your all set some say i wouldnt use it if it where only adding 1 horse and thats what i wnated to know.. i have too much money tied up in my motor to have it blow up melt pistions or anything else of that matter i guess i will look towards turbos or blowers

thanks for your time

 

Nitrous would be fine on your motor as long as the compression is still good, and you keep the A/F and EGT happy. I have a lot of experience with nitrous on motors and purpose built nitrous motors. It is not as dangerous as everyone says. I have never had a problem with it. Never. On a Bronco I would of course recommend running a wet shot, even though on fuel injected engines a dry shot can be very effective, but still does not provide as much torque as a wet shot. And nitrous is by no means cheating. If it is most of the professional drag racers cheat. I guess most of the prostock guys have "slow car" (as mentioned earlier) and only use nitrous to make them kinda fast or whatever. It is a power adder. If you think of it as a cheater you have watched to much fast and furious. Nitrous is used as soon as traction is allowed and used through the end of the 1/4 (or 1/8). Keep power levels small and work your way up. This is always the safest.

For my two cents, nitrous in small quantities and properly installed is fine. I have not personally run it yet. In exploring what is needed, if you follow the manufacturer of your choice recomendations you should be fine. One way of looking at nitrous is which you prefer for your driving, a high Hp motor and the quirks of driving it everyday or if you just want a solid motor most of the time and go like hell once in a while. Just a matter of looking objectively at your driving style and needs and building a motor to reflect that.

I have a ford F-150 truck and Id like to squeez some extra umph outta it i just got done getting it built and it has a compression ratio of around 10:1 its carb so i was looking at a plate setup they are fairly cheep also i was looking at the fogger setup drool drool but im in need of some answers id like to talk to someone about it the peopel up here really dont know and they just want to sell me something i want answers with someone thats used it

 

im just wondering but why do you want nos in your truck? if it's power you crave change the carb, get a exhaust kit running glass pacs and dual 2 /12 - 3 inch pipes with a cat system, headers, 4 barrel carb, high pro fuel pump, ect ect

 

I'm sure that Bronchris is speaking from experience. I don't agree with some things though. Stock engines and nitrous do not mix unless it came with forged pistons, like a Mustang GT for example. Ask any pro engine builder or machinist. They don't even recommend it with the hypereutectic pistons, and they are tougher then the factory cast.
Also, it is possible to add the nitrous too soon. It's only safe at wide open throttle, and when your engine is in it's "power band". Trust me. I've seen blocks split in half, pistons melt, and engines explode like grenades. If you have lots of money and don't mind buying engines and parts after you ruin them, then go ahead and experiment with nitrous. On the other hand, if you want extra power on occasion, and want your engine to last, you need to educate yourself before you spend one cent. There are all kinds of books on the subject, as well as info on line. The drag strip is a great place to learn from the pros too. I've found that most are more then willing to talk about things they've learned from experience. Using nitrous without being smart about it is like having unsafe sex with a stranger.

 

true enough and thats why im asking the people on the board before i go out and dump money in a system. Im not sure how my motor in my truck will even run its in there but it isnt all hooked up yet im just searching other options to make more power. I have a 770 holley street avenger carvb on it i already have headers duel exhust free flowing flowmaster 40 exhust and a pretty healthy cam. Like i said i dont even know how it will run im hoping very well because i built it to race in the mud. Im not sure i even want to risk it because i dont want to push the button and have my motor come all undone im just exploring ways to get the most out of what i have and if that means swaping out the heads to get a higher compression ratio and putting on a different air intake with carb then im going to do that it seems as though the cons are fair greater then the pros and thats why im asking questions not buying a 300shot setup and saying gety yo

thanks for all the input i think im going to search other alturnatives to MORE POWAH

 

I've seen it on kids shirts as "Naws" and pronounced that way, it drives me crazy. The whole time I was groing up we called it Nitros.
