Turbocharging of a basic engine type to suit different ratings and applications poses many problems. Careful design of components, choice of turbocharger match and supporting equipment are all critical in obtaining the optimum solution.
The addition of turbocharging to an engine type permits it to leave behind some of the restraints of its naturally aspirated form. However other factors are encountered which set limits rather than offer advantages.
The successful optimisation of all these factors within one engine type permits the benefits of component and configuration rationalisation to be realised while still retaining the performance diversity and flexibility necessary to meet the needs of the market place.
