I've been seeing these systems where instead of nitrous, it's either propane or Co2 injected into the intake? Just wondering what everyone thought.

CO2 as in carbon dioxide??

are you sure about that?

Never heard of this jinxricerboy. If you spraying c02 or propane into the intake... the charge will get cooler, but ya shouldn't really benefit from it since it's taking up the space of oxygen and nitrogen in the air... technically I'd figure you'd lose power.


Unless you're seeing the 'N ter cooler' setups that spray c02 or nitrous on a turbo car's intercooler to get the charge air cold....these setups don't actuallly spray anything into the engine.

since carbon dixoide is anti-combustion agent wouldnt this extra CO2 decrease the kaboom in the cylinder?

correct, think he's offabout the c02 but X2 is talking about what I know with a water or mist spray for ic's, or nitrous to cool em.

What I'm talking about can be seen here:

It's actually called Cryo2, made by DEI. The CO2 (carbon dioxide) gets injected into the air/fuel intake charge to cool the air and fuel charge. They say it's less cosstly than nitrous, and easier to expand the system (purge valve,etc.) They have intercooler sprayers using the same principal for turbo cars, but now they are offering 10-lb bottles like nitrous for N/A vehicles. Seems like a legitimate system.

cheif, from my understanidng of this link. it's not passing in the Intake. it's a basically a coolerfor your fuel line, such as the effect of coolant to your engine's water supply.

even for the air intake chamber, it seems to be a sleeve over your CAI piping. so as to cool the air charge, the CO2 is the cool these devices. not to pass through your engine.

there are benefits to having your air / fuel entering your combustion chambers. but i wonder exactly up to what temperature you would see an advantage?

Ok... here's my $0.02 on the systems from CRYO....

1) The intake cooler... it's an INSERT that is chilled by the CO2, so the carbon dioxide never makes it into the intake charge... think of putting a ice cold coke bottle into the air path of a blowing fan... the air that passes over the bottle will be cooled and you will feel the results standing infront the fan.. but you won't be showered with coca cola. That's why if you expand the system (add more CO2 chilled devices... you'll get colder intake charges. The downside I see is that it adds restriction to the intake.

2) The fuel cooler. Upon first inspection... ti seems like a kick ass idea.... cool the fuel (which is pretty hot most tiimes since it's cycling thru the hot ass fuel rail all day. The idea is that a cooler fuel charge will in turn cool the intake charge and produce more power..... Why do I think it WON'T work as they said it should ? Fuel evaporates in the bowl area, around the valves right before the intake event occurs... the extreme heat on the valve back and intake manifold assist in fuel vaporisation... keeping it in a mist or even gaseous form, which would help attain a more desireable fuel/air mix. IF the fuel is considerably colder, this vapourization may not occur as it should since the fuel is more dense due to dropped temperatures. Also I doubt the cooling effect on the intake charge air would be anything more than negligible since there is a ton of heat starting from before the injector all the way to the valve even before it opens.

Anyone else see the problem with the fuel one ?

Excellent info as usual, X2. Thanks!
