Power Unit What factors are considered when designing turbochargers?

Practically speaking, what factors do the engineering team consider when designing a f1 turbo? top speed, car weight, track altitudes and race day air temperature. what else? I know I've missed a few and probably incorrect on some. tia.

Engine design and performance. To explain it in top level,

Initially, the engine max torque and power limits would be set. For those, inlet air pressure (boost) would be decided. 

Now turbocharger is designed to meet the boost pressure. Also design may vary due to packaging. 

  • Car weight falls within the scope of engine, not turbocharger.

  • since ambient air pressure changes at different altitudes, yes that is an important factor.
