This small h1c spool like a 14b and flow 47 lb/min.
I'd like to see some proof of this! Do you have any datalogs supporting that claim?
A 14B is good for about 200 gm/sec or 26.5 lbs/min at 70 degrees F at sea level. So you can see why I find this a little hard to believe. 20lbs/min more airflow, yet the same spool....doesn't quite add up.
There's always alot of hype concerning the Holsets, but not much real-world results.
