Intercooler Experiment #2

IC Temp Testing: Trial 2

For the second trial in my effort to find a suitable bench test of intercooler cooling I’ve swapped to a larger hair dryer to see what the affect on temperature is.

Note: I am aware that a hair dryer does not generate output air at the same temperature or volume as an IS20 or IS38 turbocharger.

Other than the change to the heat source the experiment is the same as the first.

Results for the larger hairdryer are shown on the chart using green lines.

Interestingly the temperature going into the intercooler is roughly 30 degF less during this test than during trial #1 yet the temperature at the outlet of the intercooler increases much faster than during trial #1.

This more rapid increase in the outlet temperature is apparently the result of a higher airflow rate.

Based on this outcome my next experimental setup will have a goal of increasing the airflow through the core further.
