I myself did track on similar condition, twice. I believe the humidity is even higher and heat index (feels like) is 122+F. There is no heat soak (oil, coolant, IAT) issue whatsoever. Only my brake is hot like hell, you can't even stand near to it.

The key is to keep engine cool - you need 1) less boost 2) less back pressure 3) higher timing ignition (it helps ETG).

I also suspect Dinan intercooler can be part of the root cause. I have no doubt it cools IAT well thanks to the dual core design. But it's exactly the dual core that 'block' the moving air going thru them. The Radiator behind the intercooler gets less cooling air as a result.
Yeah, I wondered about the IC blocking airflow. What IC do you recommend that’s large and without significant pressure drop?

I’m also curious if a larger auxiliary radiator would help.
