The third setup to be considered for an IC temperature evaluation adds a second hair dryer to the heat supply side.
Note: I’m aware that a hair dryer does not output air of the same temperature and volume of an IS20 or IS38 turbocharger.

With this arrangement the supply air temperature became very hot, close to the output from the turbochargers at maximum boost.
A problem was encountered due to insufficient airflow going through the intercooler and the high temperature triggering the hair dryer safety shutoff shortly into the trial.

Next will be an effort to improve airflow through the intercooler to prevent the overheat condition at the hair dryers.
