I agrees that you can pump to a accumulator and store 30-45 sec for of the lights starts but you can't use this for circuit racing or continuos on and off boost applications. It's horses for courses.

That much chilled air would require a large pump which the engine would have to drive, that sucks KW more than you will ever get back. However, you could chill down a reserve of water and have it come online with boost. A little like using ice but without having the hassle, but my opinion things start to get over complicated. Chilling the water storage while cruising will use more power but not at a time when you want it going to the wheels. My 2c
