Default Nitrous question

Just wondering if you took a nitrous kit and instead of filling it with nitrous fill it with air. In a way wouldn't you be spraying a whole lot of air into the engine thus give it a little kick in power and also be engine friendly unlike nitrous over time? Take the TB spacer nitrous set-up and inject the air right there so its forced into the intake manifold. Get a huge jet for like a 250 shot so you shoot a lot of air into the engine. It would be whole lot cheaper, just go to a gas station and an air pressure guage and fill it up for like .25 cents. Just thinking. Although it may not do anything just thinking of it during the Professors lecturing.

there was a thread about this a while back, and somthing about it would just end up melting your **** because of the flammability (sp?) and its explosive (raw oxygen)...

somthing along those lines.

The 2 parts nitrogen act as a stabilizer for the oxygen

Hmmm, interesting question. I doubt if it would work using a nitrous kit. I believe you thinking off a poor man's SC by fircing air in the TB. The problem I invision include:

1) I'm not sure of the nitrous setups, but I doubt if you could get enough pressure out of the regulator to do any good.

2) You would be injecting behind the MAF, throwing off you A/F ratio?

3) If it could work, I wouldn't use regular compressed air from a gas station. Get the bottle filled at a SCUBA shop so you have much cleaner air.

It could work!
First, air from a Gas station is not pure O2, its filtered air circulating from the outside.
B) That's pretty much what SC does, but it would be a hell of a lot cheap, plus use it like it is "N2O", cal it "My O2 set up"
I think I'll try that!!
P.S. put it where the MAF can read it!

Are you going to try it. If so let me know how it performs.

doesn't nitrous help lower the intake temps to help out with detonating? I guess it could work in theory but I'm not sure that a nitrous set up will pump enough air to increase power much.

oh it'll prolly increase the power. but its not gunna be any more "engine friendly" in fact it will less engine friendly. the reason the nitrous is there is to act as a stablizer/buffer against detonation. i guess you've never heard of anyone popping a motor with a SC either? oh you have!! well guess why it happens with SC a lot of the time...detonation.

but if you do try this let me know, and take pics of all the parts you melt.

I'm no nitrous guru but I can see this going

Unmetered raw air into the engine will cause a lean condition and lean conditions cause nasty knock which results in

I think it is a waste of time.

From my knowledge N20 is in a liquid form while it under compression, when it is released into the atmosphere it turns into a gas which combined with the molecules in the air it turns into regular air, for the most part. It's the conversion that creates the low temperatures, the density, and the performance gains. I doubt that spraying compressed air into the motor will do much of anything, it would need to be in higher quantities which is what N20 does for you.


Correct me if I'm wrong or off with any of that stuff, but bottom line on my opinion, is that its a waste of time, and effort. Along with being something that was on many other peoples minds when they decided to use something such as N20.
