Testing to determine if the popular grill blade/ramp/scoop makes any difference to intake airflow has been on my to do list for a while.
Because I believe any change will be slight I have been considering different ways to measure the conditions inside the intake piping. I decided to try splicing a sensor housing into the middle of a stock intake hose. The housing is shown below and will allow use of both an airflow sensor and temperature sensor.
Next up will be assessing the airflow through this housing on the flow bench to get reference values for airflow versus pressure.
