When air leaves the turbo it is hot, because it has been compressed. Engines run best if they can gulp good cool air. Hence, the advent of the intercooler for turbocharged engines, like a radiator for air to cool the previously compressed air before it enters the intake system. By cooling the air the intercooler boosts horsepower more than the turbo alone.
A rear mounted turbo would have the advantage of lots of piping run to cool the air, but I wonder if you would maintain the boost pressure over that great a distance. Anyone know for sure ??
Interesting.
