GRZGORZ THAT IS NOT THE WAY TO MEASURE PISTON COMPRESSION RATIO. YOU WERE ONLY MEASURING CYLINDER PRESSURE. THE CORRECT WAY IS:
COMPRESSION RATIO=(CYLINDER VOLUME + COMBUSTION CHAMBER VOLUME) / COMBUSTION CHAMBER VOLUME......FORGIVE ME. I'M NOT BEING A [Email]SMART@$$.[/Email] I JUST LIKE TO HELP PEOPLE UNDERSTAND HOW ENGINES WORK AND HOW TO DO THE MATH....IAN, YOU CAN ORDER A PAIR FROM JE OR MAHLE BY SENDING THEM THE BORE AND HEIGHT OF YOUR CYLINDER AND STROKE OF YOUR CRANKSHAFT WHICH IS WRITTEN IN THE SPEC SECTION OF YOUR TRIUMPH MANUAL
