White Dog Racing FMIC Flow Testing

As a follow-on to the initial flow testing performed with the White Dog Racing Front Mount Intercooler I wondered what the airflow through each half of the FMIC would be.

I attached the WDR FMIC to the flow bench again, this time using a thick piece of plastic to cover one of the inlets and then sliding the coupler hose over the plastic to hold it in place and form a seal.

Then with just a single inlet open I tested the intercooler again.

I was a bit surprised by the difference in airflow readings between the two halves.  The passenger side is flowing approximately 14% more than the driver’s side.

Each half of the core has the same number of charge rows, 17.

Based on the physical appearance of the cores the only immediately obvious difference that I would guess to be causing the difference is the longer exit path that the air from the driver’s side flows through on the top side of the cores prior to exiting the FMIC.

Behold… the Unicorn!

After numerous failed efforts over the years to get a hold of a Front Mount Intercooler for flow testing, White Dog Racing sent over their product, which arrived today.

Numerous bungee cords were recruited to hold it above the flow bench for the testing.

The results of the flow test are:

The red bar shows the airflow through the FMIC core without the inlet hump hoses attached.

The pattern when adding the hoses to the inlets has been for the airflow through the core to increase, that was the case with this FMIC as shown by the blue bar

This setup is not very appropriate for comparing with the SMIC’s that I have previously tested since the SMIC’s were tests of a single core, and the SMIC cores were attached straight to the bench, where this FMIC required the elbow silicone coupler to attach to the bench.

The obvious next question after seeing the FMIC result is “how does that compare to the SMIC’s?”  I have included the highest flowing single SMIC that I have tested on the chart, the SRM SMIC, but it should be understood that this comparison between FMIC and SMIC is far from ideal.
