Message just wondering if we could discuss intercooler airflow/volume measurements for a minute. I was tinkering with the windows calculator whilst trying to regurgitate some basic school lessons and here is what I came up with during a comparison of a FMIC and my Z1 BA smic's. how wrong am I? (because I know I am)

all calculations are for ONE intercooler.

Z1 BA sidemount intercooler
Dimensions: 10h x 8w x 4.5d

uncompressed volume: 360 in^3
external air surface area: 120 (240 in^2)

-----

standard fmic dimensions
Dimensions: 11h x 22w x 3d
I Calculated this as essentially one 5.5h x 22w x 3 intercooler, if you cut it horizontally

363 in^3 uncompressed volume
121 (242 in^2) external airflow surface area

difference
+- 3in^3 air space per IC
+- 1 in surface area per IC

understanding that internal volume isn't listed, and that you would have to essentially fill it with water to get an exact measurement then convert to inches, I calculated everything as an empty block, rather than individual row capacity.

thoughts?
