Nitrous Lie Or Truth
Nitrous will wear on your motor more. Now is it "bad" well technically racing your car is "bad" but we all do it. A well set up n20 sytem with a proper tune will run a very long time. I've seen guys run 100's of bottles thru close to stock cars with minimal issues! My engine builder told me if you used it regularly it could take away 20% of the life span! He means 5 x's a week.

and... people will say this and that about nitrous... its hard to say... every car is different.
GENERALY speaking it is compltly safe as long as done correctly...but who is the one to say you dont have a piston wiht a weak ring land?? You never know...
But you could have 150,xxx on your car and i would say spray it. 100 shot on a healthy car regardless of miles will be fine (assuming everything is done right)

I know nitrous is a little more hard on parts but from what all the engine builders have told me it cleans your engine out a bit.
For Example I've always been told to find a high mileage engine and dyno it. Then run a 40 shot through it and dyno it after that. Ive always beentold the second time it will dyno a little higher because of the nitrous cleaning it out.
They also said this in car craft where they put all the nitrous they could to that junkyard 350 until it shot flames out the carb and melted a bunch of aluminum to the roof. Haha i wish i could do that.

Clean carbon out, people mess up when they get stupid and dont pay atention to what their doing. 99% of the times I heard an Lt1 breaking on gas was owner error, look at Frans96SS car, thats a bolt on car with a big shot and it lives. Lt1s can be dope fiends if you set them up right.
Nitrous gets a bad rap because of improper use. Use a weak fuel pump and hitting the button once can destroy a motor, that is the weak pump that caused it though not the spray.
As far as how hard it is on a motor, the extra power is there and put through parts far less often than boost and with the parasitic losses of a blower a 400rwhp blower setup is actually making a lot more at the flywheel than a 400rwhp nitrous or NA motor due to the power being consumed at the front of the frank to drive the blower.

150k w/ spray and loving it!! all about doing it right. The first few times you feel funny atleast i did knowing that i was laying down 100 extra hp but then its all gravy. ITs also sick to race ppl who just barely beat you b4 and lay the smack down on there asses.
Nitrous is a catalyst. That means it allows for more complete burning of the supplied fuel. It will assist in burning any available fuel there. You need additional gas either in the form of a 2nd nozzle in a wet kit or bumped up fuel pressure in a dry kit to provide fuel for the nitrous to attach to. If there is not enough fuel added the nitrous will attach to something else to use as fuel. Sometimes that may be the carbon build up, which would in turn clean the motor but more times than not it is a piston. This is why people melt pistons on nitrous. This is also why it is CRITICAL to have a fuel pressure safety switch on your system.
If done properly you should be able to run nitrous on a motor and not have any problems. The problems arise when people run more nitrous than they are providing fuel for, or run enough to create more horsepower than the internal components can support.

friends car has had a ton of nitrous through it and has never ever had a problem, its set up right. However not done right can and will cause problems, like the ls1 car I saw catch fire at the track... ooops

it's not a catalyst. it's an OXIDIZER.
if it was a catalyst there would be no need for any extra fuel. look up the definition of a catalyst if you don't understand.
it works by being able to get a lot more oxygen into the cylinder. more oxygen means you can add more fuel.
anyway, nitrous isn't BAD. it's all dependant on the setup. you see higher cylinder pressures (obvious from the very nice torque) and if your engine isn't able to handle that then it just isn't. so, it's all relative. if you have fine compression and your LT1 is operating like it is supposed to be then it can handle quite a bit of nitrous use.

i just read the first line of your post in my initial reply, but now that i've read it i'm pretty shocked. your understanding of nitrous and chemistry is way wya way way way off. do not ever give nitrous advice ever again until you do a lot of learning. it's ok because everyone has to learn at some point, but seriously, your misunderstanding of nitrous could cause problems if someone believes you.
i'm not going to rip it apart or anything, but a piston is sure not going to be a fuel source and your reasoning for everything is just wrong. there are plenty of nitrous write ups available so i dont' need to repeat it.

And this would cause you to have a bdad day....Just something to think about
i don't need to think about it. i understand basic chemistry and that is also nothing like the explanation he gave. i simply stated that nitrous isn't going to attatch itself to whatever is avaialable and create combustion just because it's an oxidizer. you obviously need a certain amount of heat to burn whatever specific substance. there's a difference between melting and burning. sure you can melt a piston (aluminum melts around 1300 degrees F), but why don't you find me the flash point of it. OSHA doesn't even have that information available.
