You have all the components. But described it wrong. Air into the compressor is at atmospheric pressure or may be a little higher if you take into account the ram air effect when the vehicle is travelling forward. It may be heated a little by that but not significantly.

You are thinking of the compressed (boosted air) which is "after" the compressor. This is why we have intercoolers. To cool the compressed air before it enters the inlet manifold.

You are also thinking of compressor stall. Either way only exhaust gases "power" a turbo. If you disagree do some more reading.
