Turbocharger, Supercharger and Ram Air
for your 2005 BMW 325xi
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 BMW 325xi's own movement.
How can you tell which method is best for your BMW 325xi? 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?
