Part 2 of the test to compare pre-turbocharger intake air temperatures.
For this test there is a temperature probe inside the MST turbo inlet elbow.
This is not a true open intake as the filter is sitting within a container (box) that acts to partition the intake from the engine compartment. The box has the option for being covered with a lid, but that is not installed for this test.
Results comparing the previous closed intake and the current measurements,
With increasing airflow the temperature of the air entering the turbocharger rises with the “semi-open” intake compared to dropping close to ambient air temperature with the closed intake.

Pretty much what you would expect. I bought a used APR closed intake and added a 1″ hole and two 3/4″ holes on the side facing the drivers fender. I wanted a bit more induction noise and since I bought it used and for cheap I figured why not. I wonder how much of an affect it made on the temps.
Yes, no surprises with the relative performance. I am primarily interested in assessing what the temperature difference is, whether it’s substantial or not. My guess is you won’t change the air temperature very much with a few openings on the APR intake. I’m going to try out the MST intake with the cover on, which will be similar to what you are doing since the MST filter housing does not completely isolate the filter from the engine compartment.
I’m interested in those results since the MST intake is what I would rather be running.
