TBH I don't know what temperature I'm measuring but I guess it is the coolant temp.
can I measure the oil temp? Through the OBD interface type of guage? (P3 Guage)

I already have a bigger radiator + built in oil cooler
and I'm maxing out at 100c°
BTW what are the average oem coolant/oil temperature range?

Many thanks

You are measuring engine coolant temperature and not the coolant temperature of the intercooler system for the supercharger. I asked for clarification before, even though it is much, much more likely you meant engine coolant temperatures. I'm sure you could also see oil temperature through the OBD2 gauge.


100C for your *oil temps* isn't bad if that is your max, especially on a hot day after spirited driving sitting behind other hot cars, but if that is your oil temps after driving around town in winter while stopped at the head of a traffic light behind no one then I would consider it high. As you can see from my response, it is very situational, so any average will be a reflection of many factors. If we are talking about coolant temps then 100C/212F is normal. "Overheating" would be considered 120C/250F+. Either way, it sounds like you are probably fine.


Ambient temperatures play a huge roll in helping to cool the system. If you are in a hot environment where ambient temperatures might be 90F+, sitting in traffic behind many vehicles that are hot and producing a lot of exhaust and radiant heat, and sitting in traffic where the asphalt is 160F++, then you can add all the fans in the world, but you might not get great cooling. Okay, that is an exaggeration, but my point it that there needs to be an adequate temperature differential to effectively cool the system. A fan could help, but might not make a huge difference, depending on the fan and how much more air it displaces per minute.
