Stan, you are correct the 839 scfm number is on the uncorrected sheet.
On the 'corrected' sheet at 6000 rpm:
Volumetric efficiency was 106.9 percent
BSFC was 0.491
Fuel A lb.Hr - 144.3 and fuel B lb/hr - 150.9
659.2 HP at 6000 rpm.
At peak torque rpm it was 707 scfm
110.1 VE
0.427 BSFC
My point to the K&N rep was their formula to estimate the required cfm was different to other formulas used. No big deal. just an observation.
