How much performance am i really getting out of my tired motor?
No1 192
No2 191
No3 173
No4 134
Rings are gone in 3 & 4. So effectively i reckon im only getting about 75% of the motors massive 49kw power. lol.
75% of 49kw = not much

I think minimum comp should be around 170, so No4 is dead and No3 is just about dead. What causes rings to wear unevenly?

Its not just rings that can cause a lack of comp....

What about burnt, bent, worn valves?

Yeah I thought comp #'s above 170 were reasonable. And above 190 was good.
