Broken valves and broken dreams

[davidkerryedwards]

The CAT operators manual for my coach says nothing about optimal rpm.
It says do not run it above the rated rpm on the engine plate
(2800rpm for a 210hp na). It says it can be run at full load between
the rated rpm and 1900rpm (for NA) It does say DO NOT run it at full
load under 1900rpm (for short periods, down to 1400 rpm's) for an NA
or not below 1400rpm for a turbo. If they thought there was an
optimal rpm, why not include it within all those limits?
