It's pure waste, 100% wasted energy. Down the toilet energy.

If you were to build two motors for exactly 100hp output at WOT, one 
normally aspirated and one turboed all dialed in, the turbo one will use 
a less total fuel, and have a lower exhaust temperature. It will also be 
a smaller displacement. The same amount of ENERGY will be produced, and 
that came from the fuel -- the rest of the fuel energy was pi**ed out 
the tailpipe.

All turbos will have lower exhaust temperature. Heat == energy, energy 
== heat. The waste heat expands gases and pushes the turbine, that very 
act lowers the temperature. That's just basic physics, nothing car specific.
