> But aren't turbo equipped engines using part of the flow to improve the engine fuel quality No, turbo is used to force more air into the intake side of the engine. It uses exhaust gas pressure to spin a turbine which is used to compress more air into the cylinder between cycles. That, combined with more fuel to maintain proper balance, gives you increased combustion, thus more power.
