SAE standard for flow data??
Yes.
Anything that relates to airflow into an engine (Dyno, Flow Testing, Injection, Carb, etc) is usually corrected back to a standard atmospheric condition.
The most common standard used for performance and motorsport is Dry Air, 60 degrees F, 29.92" Barometer.
If you use an non-computerized Superflow bench (and I guess most people do), you might not have come across it, as Superflow have always said that the corrections were build into the measurement method.
But.. their new computerized benches apply the correction factors automatically.. as do other software packages like Port Analyzer & Pro Flow.
