if the bag was sealed, it would explode.

Even thought the dry is is extremely cold by doing this there would still not be enough surface area of the dry ice in contact with the heat exhanger to make a difference IMO.

that would have to be some darn good tape if its -100 C

Don't do it. I've seen it done on a Typhoon A2W and it boiled over almost instantly. You'd be better off with side tanks or pockets on an aluminum reservoir.

I like putting dry ice in 2 liter bottles with some water.....makes a nice BOOOM.


I would not do it.

What about one of the CO2 Intercooler systems like this, but mounted on the front heat exchanger?

i already have that , i just used the purge from the n2o instead of its own dedicated system, it doesent have as big as an effect on a2w systems

by bag i meant paper bag that you get dry ice in from the grocery store. (or maybe that's just the grocery stores around here....)

The people that have already said not to waste your time are exactly correct. Carbon Dioxide changes phase directly from a solid to a gas as it boils. The water coming into contact with the solid material is repelled by the fact that the surface of the dry ice is boiling away. The moment water comes into contact with the surface, it violently changes phase and boils off to a gas.
Have you ever poured water on a glowing piece of steel? The water dropplets dance around and last for a while. As the water comes into contact with the extremely hot metal it vaporizes the outermost surface of the water droplet so instantly that its own steam propels it away from the heat. The same thing happens with the dry ice and the water - a solid and a liquid with the resulting gas separating them.
Besides the mechanical physics, water has very high latent heat. The heat of fusion for a pound of water is more than four times that of a pound of dry ice. That manes that water will absorb more than four times the amount of heat melting that dry ice will. Water ice is not as dense as solid carbon dioxide, so in terms of volume the Dry Ice wins, but then you have the first problem of the gas. If you want the most effective intercooling possible, keep your water ice at the lowest possible temperature below freezing that you can before its use. You could even put dry ice into the cooler with your water ice, CO2 ice will actually chill down the water ice!

man i have though of thiss a long time ago

everyone keeps saying no but ok check this out i wanted to build a alu. tank where it can vent out the bottom of the tank but run my intake tube through the tank and it would drop the iat.

i got what all of you are saying but if is in no contact with water in anyway what do you think the out come be then
