How does F1's PU quali mode obtain more power?
Why is the same power rate not always available?
Let's speak about it!
1. More engine wear.
These engine can run with a little amount of knock. They can allow for some more knock, but this increases wear and so can only be used for a few moments of a single lap.
2. More heat.
The cooling systems are minimal to keep weight and drag low. A single lap @ full power generates so much heat, the car needs to cool down the lap after.
3. Turbo as electric supercharger.
Use the MGU-H to drive the turbo on battery power, with wastegates open. Together with MGU-K this mode draws 200kw from the battery. Even during a single lap, this mode can only be used for a limited amount of seconds. Most usefull is af the start of a straight part, when the driver hits full throttle.
4. Hot blow the turbocharger.
During partial throttle, if the ignition timing is set less early, more air and fuel generate more exhaust gasses. These can be used to drive the MGU-H and recharge the battery. Ofcourse this also generates more heat.
State of charge of the battery. Because it is a single lap. The drivers can start the lap with a full battery and end with a empty one.
As u can see, most is about trickery with the ERS system and how to charge and deploy the battery. Only little to just a higher power mode.
