I've always wondered how much actual difference altitude makes in horse power.

I live in Prescott, Az at 5200' of elevation.
We notice a dramatic increase in power when we head to Phoenix, at an elevation of 1200'
It works out to a 11% to 12% increase!
We operate at about 83% of listed HP in Prescott, Phoenix is about 95% rated HP.

Heres a Horse Power/Altitude calculator:
