As I understand, fan boost allows the selected car to use more energy for a small amount of time. However, it doesn’t increase the amount of energy the car has available. The driver will still need to account for that somewhere else in that lap or another. also, it’s one-time per race. It might allow a single pass but it’s not going to make a huge change to the results.
