Forced INduction
Turbocharging
-
A turbocharger uses thermal energy of the exhaust gasses and converts it into kinetic energy that pull in external air into the intake. Since the compressor turbine and the exhaust turbine share the same shaft they spin at the same speed. This design is very efficient since turbos can spin faster when required to create more power and slower when no load is applied to save fuel.
Pros
-
Substantial increase in horsepower with better fuel economy.
-
Recycles the power of the exhaust gasses that would otherwise be wasted.
-
Multiple turbochargers can be added together.
-
Has the ability to supply power according to the engine load.
CONS
-
Almost no additional power at low RPM’s called turbo “lag”.
-
Occasional power surge when reaching the boost threshold.
-
High operating temperatures so larger or additional radiator need to be added.
