and to cool the air down to -20degC would take more energy than you are producing. theres no technology in the world capable of doing so in this tight space; and the amount of air we are talking.

if you study the video of the mapping you see that coolant temp is 82degC, not 35 as stated. the compressor-cover is 297degC; completly standard for a tuned car.

they even say that the temp from IC is about 35degC (which is fully achievable from a very effective IC), but a temp drop of 55degC between the IC and engine cylinder is not possible; mechanically (space restrictions) or chemically (sustainable, ie not liquid nitrogen etc)
