I know a lot of you have been waiting a long time to see how we test and why testing is important.

Now, I've seen a lot of info posted on other forums about how an FMIC should be tested. Some believe that a dyno test is sufficient, while others say there is no substitute for "real world" conditions.

Well, we believe in order to have accurate data in a controlled environment. It would cost quite a bit of $$$ to simulate. It was not only cost effective but, more practical for us to test 1st - 5th on road/track conditions.

The equipment we use to log FMIC data is a MoteC M48:

Equipped :

1) 3 Air Temp sensors - To log Ambient, Temp IN, Temp Out of the core.
2) 2 Pressure sensors - Pressure IN, Pressure OUT.
3) RPM signal is tapped off the stock ECU.

Vehicle - stock turbo, stock air box, TBE, HKS 272 in/out, MBC, and of course the Nisei Engineering hard pipe kit w/mini battery (Enersys Kit). A similar set up to a lot of people out there.

Now, before I post the info I would like to clearly state this is just one of many tests planned for the FMIC's. We understand as seasons change, conditions will change as well. Unfortunately, it's winter time and the FMIC's do NOT have to work as hard in order to keep the temps down.

Upon popular request, the first core we tested was the BR. The hole on side tank is where the air temp bung will be placed.

Core dimensions : 24"x10.375"x 3.5"

The external fin configuration approximately 9 FPI.

The internal fin configuration square approximately 8 FPI.

Inlet pipe 2.25" O.D. Outlet pipe 2.5"

The Nisei core : 25"x 12.625"x 3.5", 12 1/2 FPI square split design internal / external, cast end tanks, with CNC mounting bracket. Both Inlet and Outlet 2.5".

Here is a couple of pix so you can get a idea of the differences.

As stated in the beginning of this thread, we will continue to test in different conditions / seasons.

Without conducting rigorous tests, you would never get to see what really goes on with your FMIC!

Stay tuned!

Great post Kevin, glad to see you are finally posting the different results between the other competitors, can't wait to see the others.
