The Limits of Engine Speed: Why Cars Can't Go 1000 MPH

TLDRCar engines have a maximum speed due to the limitations of engine parts, valve flow, and combustion. Stronger and lighter parts can overcome the reciprocating masses that limit engine speed. Valve flow can be improved with stiffer springs or pneumatic springs. Combustion speed is affected by factors like temperature, pressure, and fuel-air mixtures. Short stroke engines, like those in F1 cars, can rev higher due to lower piston speeds. However, there are trade-offs to consider in terms of power and cost.
