I really don't understand how someone could possibly make 50+ HP from spraying nitrous ONTO their intercooler, even with a large FMIC. Even with the addidtion of a new intercooler. Maybe if the NO2 was sprayed into the intake at the intercooler, but only on the outside? 50 HP? Doubt it...I can understand why people would use the CO2 and NO2 to stop heat soak and keep things cooler, but not as a performance mod. The CO2 definately seems like the safe bet, and a better deal.

Not necessarily. NO2 is not liquid when you put it in the tank, so they fill it based on pressure. C02 is liquid, therefore must be filled based on liquid weight. If you fill C02 blindly, you risk putting too much in and having it expand later and build up some seriously dangerous pressure.

Quoted from another article that I wrote:
Nitrous Oxide is stored in bottles at approximately 950 psi as a liquid (at 70 degrees). When released from this pressure, it quickly drops temperature to approximately -127oF and comes out in a gaseous form.
Obviously this is true; you buy your nitrous bottles in measuremnts of weight: Ie: a 10 lb bottle, you regulate nitrous pressure via bottle temperature; this is the purpose of a nitrous pressure gauge and a bottle blanket/ bottle heater. If you heat a nitrous bottle, the bottle pressure increases, if you lower the bottle temp, the bottle pressure decreases. You have to maintain a constant temperature in the bottle with respect to when you tuned it, as different bottle temps will alter bottle pressures significantly enough to alter the tuned air/fuel ratio.

I'm used to paintball nitrous tanks, where they use gaseous nitrous to prevent fluctuations in pressure based on temperature. Thanks for clearin that up!

It's not bad in the sense that it won't lean you out and blow up your engine...however, CO2 displaces area that would normally be taken up by air, causing you to run a little more rich than normal. So you would be lowering your intake temp...but richening the mixture. I still suggest not using this on throttle (unless you're just cruising prior to a run)
No it's not Turbo'd

It's for getting stuck in traffic with no air flowing through the IC on a hot day to keep the intake temps in check so the car won't die. That's all.... well maybe in the staging lane at the track too.

If using Co2 is bad during heavy throttle use, unlike wet nitrous... then it stands to reason it's more like wReX said to use when idle sitting in traffic with heat soak... if THAT is the case then it's a real bad idea, since where are you going to put your 400 Intercooled Hp down when you're in traffic. You should'nt boost in Traffic.
If your friend/whomever you want to race in in traffic, still wants to race you once you make it past that accident with all the cops around, then :
1: He's got the same Heat Issues you do Turbo or Non.
2: You both need your heads examined, since you're racing near cops, and right after you saw an accident...
If you're using it after standing in line at a drag race. I could see it becomming usefull, but then running out shouldn't be a real issue, and it's not something to tune for... and is fairly limited to drag races, since the first lap in road racing is pretty much a throw away anyhow...

Maybe I should clear up that I'm set up non-seq so I DON'T even hit boost at all in normal daily driving. The intercooler just gets burning hot from being so close to the engine that when I stop with no airflow through the IC/engine bay the car literally dies(shuts off) because the intake temps get so high. Make sense? I don't drive the car normally like this but seldomly I need to drive the 7 in this heat and need something to help combat the heatsoak.

there was a write-up on a website i found a few months ago comparing the two systems. the co2 system gained just a few hp to the wheels, while the nitrous was getting considerably more. they covered the intake and the two systems were pretty identical.
the nitrous is more or less being sucked in, as some have stated, while the co2 can actually choke the engine because the engine needs oxygen, not waste.
i did find another system that is used to spray co2 to either side of your vehicle, so that it gets sucked into your opponents intake, causing a considerable power loss at the start. all they think is that you're purging your nitrous
