I only ask because it may not reach 1kpsi, or might very well surpass that pressure level and that could raise possible safety issues depending on the vessel.

tried a dry ice intercooler on an rx2 in the 80s
intake basically running through a canister filled with dry ice.

okay okay.... well normal ice. freeze it very cold. put an exchanger, such as a radiator or ac condenser at the bottom of the cooler. then put the ice on top of that. when u staging, u flip on ur watercooled inter cooler pump, and boom, cold breeze in yuh plenum88sins wrote:sMASH wrote:Use a water cooled intercooler.

that gonna go thru sublimation so fast it eh even funny, and all the cO2 will leave the reservoir.
If it's sealed, u hadda be sure the reservoir can handle the pressure build up otherwise all you go hear is pop & see one setta smoke looking thing all over the place

that wouldn't work. because even tho dry ice is cold, it's temps at ambient pressure are not low enough to get the required effect of cooling the liquid/gas passing at speed thru a pipe/intake/intercooler. Basically flow inside would be moving too fast for the dry ice to cool it.
however, cO2 gas is much colder than it's solid counterpart, so a fine spray of cO2 gas vented directly across an intercooler would work, provided you have enough gas at high enough pressure to run it for a while. Essentially, lower temps can be reached by venting the gas directly across the surface of the chamber containing the gas/liquid to be cooled, and it's cooling smaller chambers with smaller volumes so efficiency increases. Only problem I can see is making sure the cO2 hits and stays on the surface to be cooled as long as possible. Easy enough to do, shield the rear and sides and the base, leaving a vent on top rear and the front open with a front mounted fan and your cO2 nozzles between the shielding and cooler. Shielding would have an additional small benefit of keeping some of the heat from the engine/radiator off the intercooler.
