  1. maybe you could add also 4. at such high revs filling the cylinder with fresh air and fuel, mixing it before ignition, and pushing exhaust gas out becomes an issue ? for example using direct injection, air and fuel have only so little time to mix, so if you have pockets of very lean or very rich air fuel mixture, combustion is less efficient and slower, making point 3. even worse
