Marginally higher engine bay temperatures don't really have a meaningful impact on the running temperature of the engine, since it's cooled by the radiator.

But let me extend your thinking: turbo is pushing superheated air at some point. Which rapidly reduces power. Or would you say an NA engine faces the same issue of hot air intake? My experience with turbo engines says they’re affected by heat soak more so than NA engines

I wonder what the weight difference is between a turbo 4 and a big honking V8?
In off roading, weight is rarely your friend. But, I have also experienced the explosion of a wagoneer radiator on trail. scared the crap out of 3 of us. Lupinsea had to drag the wounded wagoneer a good part of the way out of the woods and back into cellphone coverage area

The issue is when, as Nick points out, the cooling system isn't sufficient to extract all the heat, whether due to insufficient airflow through the various radiators. This isn't unique to turbocharged engines. |

But you don’t think the normal engine heat plus a hot turbocharger is any worse per cubic foot of metal than an NA engine? I don’t know the difference. I don’t have a laser thermometer so I couldn’t do the measurement. And do you think a turbo in this high load low speed operation would have the same heat soak power reduction as an NA engine or more or less? The reason I’m asking is because under severe hot weather with AC on, any four cylinder turbo feels like the small displacement engine it is —I.e. turbo advantage seems neutralized. Whereas I haven’t run into this with bigger displacement NA engines under the same conditions. It’s all subjective but if you had more objective thoughts that would be fun to read.
