Yes but heating does not increase the mass. If you don't send more mass airflow over the turbine, do you think it will perform better?

I meant your turbine throttle, typo. You have to take airflow, turn it into rotory motion, and turn that into electricity or torque via some driveline.
How many hp do you think are available at low/mid throttle and rpm for say a 2 litre engine for your contraption? How much after the conversions? if it is less than 100% efficient at converting the incoming air back into vehicular propulsion then it sounds like a losing scenario to me as compared to no throttle.

There are direct injection gasoline engines, becoming more and more common. If they made it with a throttle plate then the designer would be promptly fired.
