A turbo dosen't create much heat, the little heat that the bearings produce 
is washed away by the oil. With high efficency turbo chargers most heating of 
the intake air is mostly caused by the fact that as a gas is compressed it 
gets hot. A turbo is a device that converts waste heat and pressure into work 
or horsepower. It does this by forcing more air into the engine to produce 
more horsepower.  One drawback is that turbos concentrate and absorb heat 
produced by the engine. Some diesel engine manufacturers attache a turbine 
impeller directly to the crankshaft, which is a little more efficient than 
using it to compress air.
