Oil temp
I have been watching my oil temp. Even on a cold 10 degrees night, I am getting up to 115 celcius without pushing the car too hard. Are others getting this high? This is a worry for the track. What can I do??? Are we aussies missing out on any cooling devices?

Already in the plan. :smile:
However, I am not so sure if FMIC is going to really help it. Those more experience in mechanical engineering may want to help me with this, but a FMIC will help getting cooler and denser air, but what is it's roll in terms of getting the oil temperature down? |

Wayne the FMIC will help to some extent.
If you can find some where appropriate to mount it. It will increase your volume of oil, so in doing so will keep the temp down as in your volume is greater, so will stay cooler longer.. Is that what u are asking?? |

Na, FMIC won't help. You mean a larger oil cooler Joe.
FMIC will only decrease your charged air temps (ie compressed air out of the turbo) because it's cooler, it's therefore denser so that increases your power figures or at least stops power from being robbed due to heat. |

this is a $67000 question and i don't know the answer apart from the little i have read which all seems to suggest that the quality of the fmic matters a lot.
it seems that two effects are at work. the more the volume of cold air you provide the engine the cooler it will run (and consequently lower oil temps) however this increased efficiency should also make the engine run hotter! this then explains why some people report hotter temps with an FMIC. it would make common sense that the ecu should need to be reprogrammed to understand a completely different flow rate and to adjust for these two compensating effects. anyone know this stuff? please chime in. |

Mine settles the needle width past 110 so 112, on a hot afternoon with some hard driving it went to about 118 the drops back to 112 at cruising speed. I must say I don't seem to get full power unless I am about 110-112, even at 100 if I wind it out in 2nd it doesn't feel as strong as at 112. Maybe the car only gives full power when it thinks the engine oil is at peak operating temp.?

ha joe! I told kel to get the natural ON stuff - she got the other stuff! :/
professor, I have no idea. But I've not heard of a FMIC lowering oil temps because the engine runs cooler.. |

kris my 101 on this tells me that a car's engine has two methods of cooling - crankshaft, camshaft, etc cooled by oil and the rest of the engine cooled by the radiator coolant. so an engine oil cooler and an FMIC should therefore have impacts independently from each other but both affect the engine's running temperature. in fact, i once read about a system in PM that used the FMIC to cool oil as well as the turbo air using ambient air temperature which seems to reinforce this. correct me if i am completely off target here?!

News to me but sounds on the money!! I don't think an engine will ever run 'cool' as such though.. even if the air temp drops by 30degrees Im not sure the engine itself would cool by any measurable amount!?

More power ALWAYS equals more engine heat output. So if the intercooler made the engine produce more power, the engine would also have bigger cooling demands.
WAY, with good airflow at higher track speeds you might not have too many cooling issues. If using a stock setup, the brakes will probably give up before cooling will be an issue. |
