Turbochargers do not compress exhaust air, they compress intake air using already-expanded escaping exhaust gas. It is possible this restriction preserves (localizes?) some heat but based on my very, very basic understanding of thermodynamics I would expect some exhaust heat to be "lost" to the work of compressing the intake air. I'm not sure how this would manifest. In the end I suspect exhaust gasses are still hotter in a turbo setup but as a side effect of ramming more air through the intake and burning more fuel per cycle.
- Dork1234 5y agoTurbochargers take exhaust pressure and convert it to intake pressure. The normally work on a ratio of about 2:1, where 2 pounds of back pressure (exhaust pressure) is converted to 1 pound of intake pressure. Since this pressure(and gas expansion) is normally wasted (except in aircraft where it can be used to propel the craft forward) it is a consider more efficient than supercharged setup.
