ok guys now this is proably just a dum ? but would injecting pure oxygen into your motor give more HP?it does make things burn faster right?ive just always wondered and had the thought of trying it.i mean light a ciggertt and put pure oxygen to it goes up fast.

Yep, you'll be hell while you're well! :lildevil: :nopic:

Take care. You'll need it.

Why bother though? Using nitrous oxide increases the O2 levels into the intake which is how you get more O2 to the engine. It's a lot safer than carrying around pressurized O2.

HUH? :eh: Why don't you just use liquid oxygen and a convertor from a fighter plane. BAAAAALOOOOOUUUUIEEEEEEE!!!!!!! I don't even want NOS on any of my cars, IMO anything that's under pressure in a bottle, doesn't belong in the trunk/back of a vehicle that's on the street where there's even the remote possibility of it being punctured in a collision. :onfire: On the other hand, if your involved in a collision where the NOS starts leaking and there's no fire, everyone involved will be laughing their a$$ off as they exchange drivers info...this could be a good thing. Maybe the automakers should use NOS instead of CO2 to inflate airbags...in a collision the airbags deploy, then deflate, expelling the NOS into the car...everyone still living is laughing while waiting for the EMTs to arrive! :lol: Also, lets inflate our tires with hellium...in theory the car should have less GVW (gross vehicle weight) thus increasing MPG!

8) After all Mike, they say laughter adds 8 years to your life. :lol:

N2o is an inert gas and acts as if you adding compression to you engine. Pure o2 will just combust and make a really really really really really really lean mixture.

Well there you go see...the scientific explanation from the Professor...thank you Dr. Snaggle Tooth! :lol:

Close, but it does more too.

True, N2O is safe at ambient temperature. But, at 570 degrees it splits into oxygen and nitrogen so it does add oxygen during the combustion process. The additional oxygen allows the engine to burn more fuel - thus giving more power.

Secondarily, as N2O vaporizes, it has a cooling effect. The cooling increases the density of incoming air allowing even more oxygen to enter the combustion cycle.

Take care.

well if you are going to get technical neither adding oxygen nor NOs is going to increase power but if you add either of those ALONG with some more fuel then you can increase power---otherwise you just make a lean burning engine and that is a close cousin to a blow torch---melts the crap out of aluminum......................Dan

:? I thought I said that. Don't you think I said that? Sure I said that. Why doesn't he think I said that? Well, maybe I didn't say that exactly, but I meant that. No, I did say that. :)

Take care.

I think maybe the pure oxygen injected into a previous post with the exhaust of his engine to pressure/boost his intake would make a good video 8O

Ok that might explain why you need a bigger carberator with NOS.
I wonder what the % of nitrogen is in the oxygen to make Nitrous. I am not sure but the welding gas for a mig is a nitrogen mix I think 20%?? . Can anyone clear the fog for me this morning.

As previously mentioned, nitrous is one way to add more oxygen which allows you to add and burn more fuel which = more power. Nitrous is 2 parts Nitrogen to 1 part Oxygen. Nitrogen stabilizes the oxygen so it isn't quite as volatile, but it is not completely inert either. Unlike medical grade nitrous at your dentist office, nitrous for automotive use also has some sulphur in it so don't huff it or you may get sick. You do NOT need a bigger carb for nitrous. It has little to no affect on carb sizing for your motor. Nitrous kits inject the needed amount of fuel along with the nitrous so you usually don't need to adjust anything in the carb for small kits. Some custom EFI kits use the fuel injection system to add the extra fuel to go with the nitrous. But that is a whole other story. You may have to retard your timing (more nitrous = more retard) though so follow the directions with your kit for that. You can use smaller nitrous kits on completely stock motors and if used as calibrated and directed, it will not hurt the motor at all. Larger kits require engine mods to handle the power level. You would have to make virtually the same improvements for a naturally aspirated motor that was built to make the same power without nitrous. Stock motor parts are only meant to handle so much power, no matter how it is made.
As for being a hazard in an accident during normal daily driving, the bottles are removable, and they should be removed in daily drivers until you intend to use them. I don't know anyone who drives around with them in the car everyday.

Thank you very much Dave that was some real usable information, and it cleared a lot of my misconceptions up.

Even with a 50-75 hp shot it is also reccomended to replace torque convertor to one with a balloon plate, any NOS kit less than 50hp is a total waste of $$ IMO

I know a lot of people who drive around with bottles in their car everday, including myself (when driving my pocket rocket, no NOS in my elky)
