In summary, psia at 7000 ft elevation is 11.35, so:

11.35/14.7 = 77% of sea level atmospheric pressure in the intake manifold, or a 23% loss of power, even more than in Denver

I just moved to colorado (6700 feet) and I was wondering how I could calculate the power loss.

I've read that N/A loses the most power...then superchargers...and turbos are virtually unaffected.

Just wondering if you guys can help me properly guestimate how much power I'm losing up here.
