C250 Turbocharger question
Hi everyone,
I just purchased by first every MB - 2012 C250 coupe in tenorite grey (+ the lighting package of course haha). Anyways, I did drive both the C250 and the C350 before finally deciding upon the 250 model (here in Canada the price difference is an extra $10,000 between the two models and I couldn't justify spending that much extra).
Anyways, I have a complete newbie question to ask. Since the C250 has a turbocharger I was wondering how that works. Does it add extra HP to existing 201hp or is it 201hp including the turbo? I'm moving up from a 2003 Buick Century (dad's old car) so this is quite a jump up for me haha!

^ What he/she said... The way a turbo works is that it takes some of the exhaust gas being expelled and enters the turbo to build up air pressure, then after cooling it down and then filtering it, the pressurized air or "boost" enters the combustion chamber allowing for more air in the combustion, allowing for more power. This is why after "tuning" the car, you can increase boost PSI than factory allows, thereby increasing torque and horsepower. But there are tradeoffs to everything, increased boost can't be handled by all components, an engine is only as strong as its weakest part. So durability and reliability is sacrificed, sometimes requiring extensive and costly internal components to allow for increased boost - safely.
