No problem with the high pressure against piston ring. I calculated the size of piston ring adapted for cylinder bore after Prof. Chaddocks methods how to produce own piston ring. The material in ring are made of camshaft from Peugeot engine, the camshaft are made of cast iron with hardened camlope, camlope are impossible to machine with tool. Between camlope are soft and are used to make piston or piston ring to model engines. I has used brake disc to produce small piston to my 0.5 cc diesel engine and piston ring to some of my model engines. Brake disc are made of cast iron.
