With temps between 5 and 15ºC I'll struggle to not going over 75-85ºC, the cold air cools too much the engine and gives you false readings. And people starts to lean it
Between 15 & 25ºC I'm pretty confortable between 95 & 105, 110ºC as maximum.
Over 25ºC is happy hour time, but I tune mine engines by ear and check the temperature only to assure myself that nothing is wrong there, doesn't matter if to go happy needs to go at 115 or 140ºC, each engine is a world apart and each one needs a different temperature. I have one engine that 'awakens' when temp reach 130ºC, under this temperature is a lemon.
Have seen one engine running happily at 150ºC.... each one is different. And the fuel you use makes a difference too.
Thanks Corse-R.
Many people damage their engines when the weather is more and more cold now. They usual run their engine about 120-130C during summer. But when the season enter winter now,they still run it at about 120-130C. The engine will wear fast due to not enough lubrication. There are several parts die first.
1)Conrod bushing.(worn seriously)
2)Crankpin.(worn seriously)
3)Conrod and Crank.(When the engine is too lean,they may be broken if the engine CAN fly to 40k+ rpm!)
Just want to warn all racers no matter which engine's fans. As you know that the engine is very expensive.
