Anyone ever sold "bad" nitrous, or ripped off?

[red devil]

I swear I was sold a bad tank of NO2. No matter what I do, there is little to no power given when I press the little magic button. I have bought about 5-7 tanks from this store and never had a problem. However I came in late and maybe this pissed them off. I tried going back to my stock setup and everything and nothing changes. I swear that the no2 is nothing other than compressed air. Any idea how I can test this?

Try smelling the nitrous oxide..NOT enhaling..just open the bottle slightly and take a sniff. It should have a slightly sweet smell to it.

okay after reading a bit i realize now that there is a small amount of sulfur in nitrous oxide used in cars. I was just recalling something from my chemistry class, not sure if it would have the same smell with sulfur added.

Yea you'd be able to smell the sulfur for sure, it keeps people from inhaling the shit. Trying opening it up SLIGHTLY and see what you smell. That'd be some ####ed up stuff if they sold you compressed air man...But keep in mind ive never personally smelled nitrous used for cars, but ive smelled nitrous oxide (laughing gas with no sulfur of course) and sulfur (####ing refinery near my house smells like rotten eggs). I guess it's sort of a mix of sweet and rotten eggs? But it would definetly smell different then air.

Compressed air won't weight as much as nitrous because the juice is in liquid form.

I would test the switch to ensure you are actually spraying when you think you are. You could be feeding the engine fuel but no juice.

There are different grades of nitrous. I purchased medical grade from a friend who is an animal doctor. The medical grade had a bit more punch than the industrial. Also the industrial stuff can be traced by the "warranty police" if you smoke your motor while using nitrous.

I have been given a big tank of air before. Just take it out and weigh it. If it's 16-17lbs then you got nada.

the medical stuff wont give you any more performance.

Nor can 100 part per million sulfur dioxide be detected in an engine if it's blown up. Both those statements should be dis-regarded as they are both incorrect.

The sulfur is only in automotive grade nitrous so people do not become chemically dependant on it, it has no other effect what so ever on performance or traceability.

I still havent figured out what is wrong. Just havent had time. Sorry.

Well, since I last posted back in November or so, I finally resinstalled the nitous system tonight.

I swear to god that particular bottle of nitrous is bad.

The stuff is coming out, the gas is coming out, but all that happens is maybe a 2hp increase in power. Its amazing how nothing happens.

There is "some" nitrous coming out as the car doesnt bog down when spraying. I know this because I unhooked the NO2 and just sprayed fuel while WOT and the car completely flooded. When the NO2 is hooked up, the car runs fine with some "little" increase in power, but nothing other than a freaking tailwind.

I am going to have to dump this bottle and refill. I'll post the results.

spray it against a wall see if it ices up, if its compressed air it will just blow, if its nitrous it will ice up.

 

[red devil]

OK, it iced up.

And kinda stank.

So, now I am thinking that maybe I am just running too much fuel in conjuntion with too little nitrous. I will have to start leaning out the fuel ratio and try that.

 

[madhatter210]

do you have a nitrous filter installed, is it time for a new one? if not how do your jets look? are they plugged a little? I bought a used a used nozzle for 10 bucks just for the jets and would be suprised if it would have sprayed a ten shot with the amount of build up it had.

 

[red devil]

Ok, the nitrous wasnt bad, my setup was.

Back to when I was running nitrous successfully, I was using a jetting table for the jet ratios of nitrous to fuel. Everything went swell. Then I upped the supercharger boost and roasted a piston.

I rebuilt AND installed 30% larger injectors. Replaced the fuel pump with a Walbro unit AND replaced the intank fuel sock (this caused fuel pressure to jump about 20%).

Basically, the NO2 to fuel ratio via the jets now changed dramatically compared to pre-blown motor. I have just been running WAY rich compared to last year. There was so much fuel compared to the NO2 I was only keeping from bogging the motor by adding the nitrous!

So tonight I left the fuel jet where it was and basically doubled the HP rating of the nitrous jet and what do you know, I went fast.

Now I just have to fine tune the ratios and get down the track.

I have had nitrous on 4 differant cars. I've been using Nitrous since 98, and I've never heard of bad nitrous.

I HAVE heard of dirty nitrous, and it is commen.
Make sure you use a nitrous filter, or crap will get stuck in your jets.... causeing the Air/Fuel ratio to be outta wack.

 

[psychlow]

I know I'm being picky.

BUT:

It's N2O.

Two parts nitrogen, one part oxygen.

NO2 is usless shit (pollution) you get out of your tailpipe as a byproduct of combustion.
