Hello guys im new to this. I have a question about turbochargers that is really giving me a headache maybe someone can help. If there are 2 turbochargers they are the same in every way. The only difference is that one turbocharger has 2x less rotating mass than the other turbocharger. Will both turbochargers require the same amount of energy to compress a specific volume of air to a given pressure? I know this may sound dumb, but try to understand what im saying. By having 2x less inertia, is faster response to get to a certain rpm the only benefit? or does the lighter turbo require less power to compress the air than the heavier turbo since the heavier turbo needs more power to get to a certain rpm? If we consider the adabatic compression process which turbochargers follow, nearly all the turbine shaft work is used by the compressor to raise the temperature of the air and the pressure. If one turbo has 2x less inertia than the heavier turbo wouldnt the lighter turbo have less available shaft power than the heavy turbo, because less power is needed to overcome the inertia of the lighter turbo? Would this affect the overall adabatic temperature rise?
