If I'm remembering your shop location correctly it is right at sea level, correct? I have seen the density altitude at Thermal airport(150 Ft. below sea level) be right at 8700 Ft in the mornings in June, I have also raced at the old street races in Indio in March when the D.A. was probably around 1200 Ft. The motor knows how thick or thin the air is regardless of the Pro Charger, correct
If you dyno an engine at sea level, or 5000ft. up, it does not matter...it's called a correction factor. His uncorrected HP on that pull was 895. His car has already run 9.90's in full street trim at 780HP...much faster than some Dusters out there with 750HP BB's....
