Turbocharger, Supercharger and Ram Air
for your 2008 Volvo S40
Turbocharger, supercharger and ram air all have one thing in common: forcing more air into the engine for a significant power boost. What are the differences? In a nutshell, turbochargers get energy from the exhaust stream. Superchargers get power from a belt connected to the engine. Ram air is a process that draws cold air into the engine through the Volvo S40's own movement.
How can you tell which method is best for your Volvo S40? Most auto owners find that the answer to this question lies in the make of their vehicle. However, superchargers tend to be easier to install, and turbochargers are generally more efficient. The ram air option has classic appeal. Which of these do you prefer?
