I hear nitrous oxide just cools the intake air/fuel so more air and fuel can get in the same space...

Could the same effect be obtained on a lower level by turning a can of compressed air upside down and spraying it into the intake?

 

nitrous oxide is also flamible
but with a good setup its also contained to a almost constant stream

people do use co2 in race cars though

 

The DEI CryO2 system uses co2 to cool the intake air before it enters the IM.

 

You would not want to spray CO2 into the intake air stream. For every bit of CO2 you put into the air stream, that is displacing oxygen that could bond with fuel to make power. CO2= No power. Yes the cooling of the intake air charge has a beneficial effect, but not enough to offset the displaced oxygen.

You could spray compressed air/CO2 onto your intake, or onto something to cool your intake air charge (sort of like an intercooler), but you would not want the gas itself to enter the intake air tract anywhere.

The Cry02 device runs compressed CO2 through a "bulb" that is aerodynamically shaped. This cools the "bulb" which then in turn cools the intake air charge. The company claims it is very effective, however I have my doubts about blocking the intake air flow with such a large device (the bulb), not to mention the very limited contact/surface area of the bulb. (meaning it would not drop your intake air temps very much, or as much as they claim).

You can see a photo of the system here.

Moving this to forced induction

 

just get a scuba tank filled to like 3500psi and attach the valve to your intake tongue.gif

 

also to remember...

nitrous itself is compressed air...

Nitrous is a heavier molecule that contains three oxygen atoms. Not only does it cool air... it also causing more oxygen to enter, which like random said =more power.

Nitrous is a cold way of forcing air in your engine...

 

Didn't Voidweller have that Cryo system?

 

Hmm.... so howabout a heat sink type of device with a peltier cooler on it?



Like jam the fuxin' computer heat sink into the CAI, and hook up one of those 12V thermo-electric peltier coolers from a computer, but backwards so it will cool the heatsink instead of warm it up?



think it would be worth it? Supposedly the Peltiers can freeze one side and boil an egg on the other, they're also stackable.. meaning you can utilize a few of them all on top of eachother. Maybe it could work like an air to air intercooler?

 

that looks VERY restrictive...
