I have a question regarding flywheels which I hope someone can help me with - my understanding is that early 907s were fitted with cast iron flywheels that were safe to 7400 rpm and later engines went with cast steel which in lightened and balanced form were safe to at least 8800rpm. The club store sells lightened 'steel' flywheels but they are exchange. Can anyone tell me at what point in production the flywheel material changed?
