acceptable iat range C32 AMG

what is the acceptable range for IAT? My 202 C32's temp gauge shows the temp in celcius and is in the middle of 80 to 160 range which means about 120 degrees Selsius. this translates to abut 248 Farenheit. is this acceptable IAT temparature for summer (in DC area) or is it running too hot? Thanks,
andy T

You are mixing something up. The gauge in the cluster (if that's the one you are talking about) does not show IATs. It shows the engine coolant temperature. For IATs, without any cooling mods in DC you should be about 40*F above ambient while cruising. So, if it is around 80*F today, your IATs should be around 120*F.

i have done the coolant isolation mod, CM30 pump and Frozenboost Heat exchanger installation.
Ambient temperature is around 30-33C here. And the IAT is about 42-45C in highway cruising. 65-67C in full throttle 0.8bar boost.

My car has separated cooling, bigger heat exchanger and stock (newer version) bosch pump. Running from 0 - 230 km /h (0 - 143 mph) results IAT being about 70 degrees C (158 F). Ambient temperature being 20 C (68 F).

Also running 65 mm SC pulley, ECU tune and NW intake.

Here are few logged runs:
