The main challenges include:
* Managing boost pressure: Both systems increase boost, and coordinating them to avoid overboosting and damaging the engine is crucial. Sophisticated control systems are needed.
* Increased complexity and cost: The added components, plumbing, and control systems significantly increase the cost and complexity of the engine.
* Heat management: Both superchargers and turbochargers generate significant heat, which needs to be effectively managed to prevent engine damage. This often requires upgraded cooling systems.
* Parasitic loss: Superchargers, unlike turbos, consume engine power to operate. This needs to be carefully balanced against the power gains.
While technically feasible, it's rarely seen in mass-produced vehicles due to the cost and complexity involved. It's more common in high-performance applications where the extra power justifies the expense and engineering effort. Often, such systems are seen in highly tuned racing or custom built applications.
