well its reassuring to hear im not the only one seeing temps like this. still doesn't seem smart to run them so hot for emissions and efficiency... would be wiser to have an engine that isn't on the verge of meltdown constantly. heat cycles this severe are not good for bearings and races or any friction points in the engine, regardless of efficiency. Makes it that much more imperative to keep up on oil change intervals and to keep a grade heavier oil in to keep everything well lubricated. We have turbines at work and they see 16k rpm all day long.......granted that's a turbine that's operates using the brayton cycle not a reciprocating engine however, the internal bearings are still seeing high rpm and never cross 215 degrees. my point being tied to the fact that temperature kills, and even a small 15-20 degrees that seems obsolete, in time will greatly reduce the longevity of the engine
