I run my Sportwerks .26 at about 200 (if that) up to 230-240. I just don't want to run the risk of going too far and paying the price for it by buying another engine with the money I don't have. My OS 18TZ, I haven't run it enough yet to see what it's optimal running temps are. I just don't like to "push it" too much with my engines.
Though it good to have it set so you know your not overheating its not really saving alot of life. I watched a video and read the research crap about it. When you tune it you shouldnt go by temp alone. First tune it to where it runs good and still has smoke coming out of it when on the throttle. Then check the temps, if they are too high then richen it a bit. If you run your engine constantly at 240-260 it will just about last as long as one ran at 200-220. Reason is because the engine isnt being damage at 240-260. I try to not get over 270 but if I happen to hit 280 and its running great I dont really worry about it.
Just thought I would say this because you wont really see a huge difference is engine life when comparing 200-220 degrees and 240-260 degrees and its gotta be more fun having the little bit of extra punch.
