| A stock, unhacked 1G DSM MAS will not accurately report frequencies above 2000hz. That frequency represents roughly 180 lps (380 cfm) of volumetric airflow. At standard temperature (around 77F) and sealevel pressure, that's about 210 gm/sec (28 lb/min) of mass airflow. | A stock, unhacked 1G DSM MAS will not accurately report frequencies above 2000hz.

| - | A stock, unhacked 2G DSM MAF (same as the 3000GT VR4 MAF) was designed to operate a bit higher. You'd expect overflow on a 2G DSM MAF around 2700hz. That frequency represents roughly 320 lps (about 680 cfm) of volumetric airflow. At standard temperature (around 77F) and sealevel pressure, that's about 375 gm/sec (50 lb/min) of mass airflow. | + | ==== 2G DSM MAS ==== |

| - | ==== EVO8 MAF ==== | ||
| - | A stock, unhacked EVO8 MAF (effectively the same as the 3G Eclipse MAF) was designed to operate even higher! You'd expect overflow on EVO8 MAF around 3000hz (we think...I'm not sure I've actually seen an EVO8 MAF overrun). That frequency represents roughly 420 lps (about 890 cfm) of volumetric airflow. At standard temperature (around 77F) and sealevel pressure, that's about 500 gm/sec (66 lb/min) of mass airflow. | + | |
