Speed limits 
Hello today I will be talking about speed limits.

The rule of thumb for speed and air resistance is that for a given car, it takes four times as much power to go twice as fast.

 If your car can do 50 mph with 35 horsepower, you'll need 140 horsepower to do 100 mph. For 200 mph, you'll also need about 560 horsepower. At 300 mph it would might be around 2,240 horsepower.

Main body: Does speeding damage your engine

It only adds a second of time and will save you from future engine. Transmission, or axle  damage.... Revving the engine won't speed up the process. In fact, that could cause easily avoided damage. Cold revving causes abrupt temperature changes that create stress between the engine's tight-fitting components.
