just wondering:

why do you think heating the air will make the turbine extract more energy in this case?

How does changing the angle of attack on the turbine blades effect turbine efficiency?

Can you have a turbine that can restrict air down to idle demands while providing sufficient full throttle airflow?

And of course there are enumerable energy conversions going on as well with losses, from the throttle plate pumping losses (and intercooler fan and extra weight/complexity/cost). I don't see how it could stack up to eliminating those losses (i.e. direct injection or pulse and glide).

As pete notes, you may need a somewhat sophisticated controller for your variable vanes for ok throttle response. It needs to know the rpm of the turbine (and etc) and adjust accordingly to the gas pedal

fwiw I did pick up on the engine and the brown exhaust.

Am I missing something here? Maybe a giant wooden badger would help? (Just kidding )
