It should be noted, that in any reaction, mass is ALWAYS a constant. The mass of the reactants is always equal to the mass of the products; ALWAYS. Remember, energy cannot be created or destroyed, the same goes with mass. The only variable factors are: gas volume, temperature, pressure, humidity, ambient temperature, atmospheric pressure, and rate of combustion (which includes the amount of fuel burnt). Actually, the operation of a turbocharger in a gas engine is practically the same as for a diesel engine, just a few less safety features (knock sensors/ computer etc.) but perhaps not with MB's new CDI's.

The thermodynamics governing the turbocharger are very complex, involving many variables and sometimes can be skewed, if considered from the multiple frames of reference all at once. That's why it is important to use the same frame of reference in each explanation. I explained the function of the turbocharger with a fixed reference to STP (standard atmospheric pressure and temperature).

I'm sorry if my very technical explanation confused anyone. I don't want to make this topic any more nebulous.
