I suggest a turbo for the car engine to make the car faster in my suggested stages. It would have a turbo sound effect if DRS, boost, or both are activated, that it would act like a second DRS and make the game more competitive.
With turbo, you have:
Top speeds up to 370kmh (230mph)
40kmh faster than normal speed
