That's similar to the Hyperbar setup.  Hyperbar is/was a French company
that combined very large turbos with a bypass valve and combustion chamber
attached to a diesel engine.  Very high specific output, but the light load
fuel consumption was more like a gas turbine than a diesel.  I believe the
Leopard tank had a Hyperbar engine.  I saw a demonstration Hyperbar V8 900
in^3 (15 Liters) putting out 900 BHP @ 2100 RPM.  Package size was only
increased by maybe 10% with more than double the stock turbocharged
horsepower.
