Curt,
Unlike those simple formula calculators these calculations have a number of inputs. So there is much more change for GIGO. I do not know what Crew Chief has for inputs. Here are some of my inputs and what I used.

BP = 29.92
RH = 0%
Temp =60
CD =.3
Frontal Area = 16 sq ft
Hood Scoop = Yes / 100%

If you can give me what any of those are that you used in Crew Chief I can rerun my calculation.

Thanks,
Stan
