db1994 said:Any air compressed beyond atmospheric pressure is heated in relation to the temperature before compression.
Most of the intake air change temperature increase on a turbo car comes from Charles' Law (-edit: and Boyles law) , not because the turbine is physically connected to the compressor.
Under load, touch a Vortech head unit, and a turbo compressor unit and tell me if there is a significant difference in temp between the 2.
