pabs should be qualifying in the top 10 on the grid
Well, by "freezer" I assume you mean some way of cooling the flow a lot. In general terms, and assuming you have no pressure losses, then you are right. Bear in mind that when we say cool air, we are referring at the change in density with temperature. Air, like most fluids, decreases volume as it is cooled, thus increasing density; by contrast water increases volume as it changes from liquid to solid phase. Then, consider that mass flow rate varies with density as well as velocity of the flow and cross-sectional area. Then, for a given velocity and area, increased density will give you a higher mass flow rate, provided you enough pressure to push the fluid. So if you have your fuel-to-air mixture right, you will get improved performance. Your fuel comsumption might also increase, but that's a different issue. Again, if anyone has a different opinion, please post it so we all can learn a bit more.
