Now on to heat extraction.....
Car cools fine when moving.
Cools fine when sitting with AC off.
Turn AC on not moving and just idling and you can watch the coolant temp rise, rise and rise.
Theory.
All the shit in front of the radiator (Intercooler, trans cooler, AC condenser), heat from LT headers, heat from supercharger, etc., is trapped by the lack of airflow and venting under the hood.
Solution. Chop hole in hood. Rivet hood vent in.
