Just remember....oil coolers don't make the engine run cooler. They keep them at operating temps longer. Operating temps are a function of the thermostat. Thermostats open around 180-190F.....when they are working correctly. If they open higher, then that is the temp your engine will operate at.
Temps climb when you exceed the coolers capacity of maintaining operating temps. Fans on a cooler are only for bumper to bumper traffic and actually impede air flow when they are not operating. |

It does get hotter when trashing is in order. |

I wouldn't....if the t-stat is working correctly keep it as-is. Test the t-stat, check gauge accuracy. If you are getting temps higher than 220F with 'normal driving' and the t-stat is working correctly and you don't have any internal issues.....then you need to add a front cooler.
Not cheap.....I would consider checking stuff first... |

Coming from a supercharged liquid cooled unit...this silly stuff is still all new to me. In my head the oil temp=coolant temp... http://forums.pelicanparts.com/suppo...s/boldblue.gif |

911 Gauge module overlays Hard to tell from the angle of your pic, but slightly passed 9 o'clock puts you at 200 degrees. Your gauge has a small area between 200 and 240. To me it looks like you are at 210ish. They are using your exact gauge in their photos so I'm not sure why you feel you are running hot. |

That makes sense. One thing to consider regarding oil v coolent temp: most engine oil will not boil (flash point) until they reach temps above 400 degrees - some considerably higher. This is just a comparison beteen coolant and oil temps - not saying it is safe to run with 400 degree oil temps in any engine. :D |
Check your thermostats..........
For peace of mind you have to check and inspect the engine and auxiliary thermostats operating conditions when you are having doubts about your operating engine temperature. Adding cooler without verifying or checking the thermostats is not a prudent course of action.
Picture below illustrates the three (3) different behavior or condition of the auxiliary thermostats. On the left most is the thermostat at fully stuck close condition, the middle is at the half-way open, and to the right is a normal operating thermostat (fully open). Water bath test temperature was between 185°F - 190°F. http://forums.pelicanparts.com/uploa...1368233083.jpg Thermostats out from the water bath. http://forums.pelicanparts.com/uploa...1368233151.jpg Auxiliary thermostats tested: http://forums.pelicanparts.com/uploa...1368233203.jpg Tony |

Thanks for the info MCA. |
Porsche and VDO have been supplying "vague gauges" since the early 70s. Irksome at best. You want accuracy you change the gauge to a more precise device or use an outside device to calibrate.
The hand held IR temp gauge is cheap. Shoot the beam at the oil tank, base of the engine and the oil lines. |
