I did a few searches and found only that c02 is cheaper. I was wondering what does the job better. Does the c02 cool and add more hp or does the nitrous

I'm no scientist, but I think NO2 is colder, so it would work better. However, I use CO2 because it only costs me $5 to fill my 5lb bottle. It's still cold and you wouldn't want to put any limbs up to the bar.

You suck some O2 into the intake and no big deal, suck some dense N20 in and watch your AFR head up.

how would you suck any into the intake?

C02 doesn't burn none too good, buddy.

1 - at the current price per pound for Nitrous it doesnt make sense to use it. $4 a pound vs. $1 a pound. they are both cold as **** and will do the job effectivly.

2 - your spraying ONTO the intercooler, not INTO. regardless of which you use, if it ends up in the engine you got bigger issues then which will blow the motor first.

You are actually prooving my point. CO2 will not do anything bad if it gets sucked up into the engine, it won't increase your performance any, but you won't blow your engine with a lower AFR.

Now, I am assuming that most people have done at least the snorkelectomy, or even put in a new intake, three feet from your IC.

Tell me how you can assure that the NOS (or CO2 for that matter) venting freely into the atmosphere in a confined space will not be sucked into the low pressure area near the intake. I am assuming that you are stopped and are spraying at the start of a 1/4 mile run, or worse, being a stoplight cowboy. You have no air moving around the vehicle or engine for that matter and have 30-40 ft^3 of cold N2O vapor displacing anything under the hood.

That is how you are going to suck the gas you are letting loose all in the angine bay into your intake.


CO2 won't aid in combustion as Mr. Boost so astutely noted. You suck in >30% more oxygen into your engine and don't put more fuel in? Hello 13:1 AFR, engine get hot, bad things happen.

there is no way to assure it. its just a risk you run with either of them.

however, you will add more fuel. that is why you have o2 sensors. its the same as a dry nitrous setup. nitrous (or even co2) gets into the engine, after the first exhaust stroke the o2 sensors take note of it and correct for the extra o2 in the engine by adding more fuel.

not the healthiest thing in the world no, but people have been using dry nitrous setups for years. i dont think that some residual n2o or c02 will destroy your engine.

coming to this conclusion stopped me from buying the kit. You're right.

dude, talk to half the guys around the area that are running these. Keenan could probably give some good insight on this.
