| :any IC" . That makes no sense at all. Freezing increases the density of the air so there is more mass going into the engine. correct The physical attributes of the IC has not changed to increase flow. correct If I have a pipe that is one inch in diameter and I a freeze it, is the diameter going to change to increase flow? nope At most the pipe will get smaller because might contract instead of expand. correct What freezing the incooler proves and is that the FMIC can support the extra mass from cooling the intake charge. Ummm...freezing *any* IC core will allow it to support extra mass flow. Freezing the IC doesn't drastically affect the IC itself, but rather the air travelling through it. IC's are rated for a certain CFM. CFM is obviously a volumetric flow rate. From basic thermodynamics, we know that the volume of a gas can vary drastically with temperature. Therefore, if the charge air is super cooled by spraying n2o on the core, the volumetric flow rate is greatly reduced while the mass flow rate stays the same. This reduction in volumetric flow rate caused by spraying the core frees up a lot of the CFM capacity of the IC core, thus greatly reducing the pressure drop and increasing the flow potential. Freezing the core is pointless imho. A frozen IC core is not a sustainable real world condition, and is only good for dyno bragging rights.
