| I have just been emailed the figures so posting them here so others know the answer.
Compression Ratio: 11.5±0.5:1
Engine cylinder compression measured with DDS instrument:
Standard value = 11 to 12 bar
Service Limit = 10 bar (MIN.), difference between the two cylinders = 2 bar (MAX.)
29psi difference seems to be a real wide tolerance to me, but what do I know... |
