Even with the upgraded needle wheel it will only produce 14.25 scfh. The Sicce with the red devil needlewheel will be twice that at 35 scfh. I tested these results with my friends air flow meter. This is what made me switch to Sicce in the first place. Before I was using the Sedra ksp 5000 that was only producing 16 scfh with the stock needle wheel. This doubled my skimmers output over night.....
