Which outcome occurs when a turbocharger forces excessive air into an engine with cast iron pistons?

💡 Explanation

When a turbocharger forces excessive air, pre-ignition is triggered because of a higher compression ratio and increased cylinder pressure, especially in engines with cast iron pistons less resistant to heat. Therefore piston crown cracking results, rather than bearing wear, valve float, fuel injector damage that stem from separate issues.
