What temperature do you run in cold weather(winter)?
What temperature do you run in cold weather(winter)?
Same with summer season? |
running colder in winter of course otherwise the lubrication is not enough.

Depends....
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. |

And the fuel you use makes a difference too. 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. :nod: :smile: |
When the weather is very cold,I will use small heat sink. Not big one.:batman:

in the past I have tuned by the amount of smoke/exhaust that comes out but is it just me or does the exhaust smoke seem to diminish when it gets cold out? since I have a .15FE (crappy I know) the colder temps are nice because it takes longer for it to overheat!:D
Corse-R : would you mind putting those temps in ºF...? ALSO: if I decide to not run all winter what is the best way to store a sub-C glow plug ignitor??? |

Colder air is more dense than hot air. As such, the same needle settings will lean out the engine as temp drops.
Cold air requires more fuel to keep the mixture right... More fuel means more lube and lower temps... Corse-R is on the money. Below 20-25 deg ambient temp dont try and chace the same engine temps you run at 30+ deg. corvette... google "conversion" you will have you answer alot sooner! |

Not really on topic but do you guys have experience with RB Concept fuel and Tornado. Can you tell me which one is better in term of power and maybe better lubrication?

WATCH OUT!
PUSH!:D
I just break one .21.:mad: I have an unlimited desire for more.:blush: |

Originally posted by Gped0124 If my conversions are correct, how the heck do you run anything below 100C? I cannot get my mt-12 below 110 even in summer weather. No where near 130 in cold weather... Many people wrongly adjust the punch of their engines leaning the low-end needle too much, rather than using the clutch adjustment and the gearing, make yourself a favor, as a starter, open 1/4 to 1/2 turn your low-end needle and correct the situation adjusting your clutch, you will see how your temperatures go lower. Probably you find you can lean the high end needle some little more without running into dangerous temperatures. And if you see on 15 to 25ºC temps I go between 90 to 110ºC, when temps go higher I let the engine raise their temp and adjust the carburation by ear and eye rather than with the temp gun (see the smoke trail of your engine leaves behind your car) and learn to hear your engine, surely you will improve your carb adjustments, but is a slightly steep path to learn. All depends how much dexterity you have doing carb adjustments. |
what kind of plugs are the best in the cold weather?
i'm running a .15FE (pittiful engine I know) |
