I was thinking that physical elevation is only part of the equation to get Barometric pressure... You could be at 3000' at one place with a higher BP and have an engine produce more horsepower than at 1000' with a lower BP. I take it this is correct? The belief that engines lose power with elevation must stem from the fact that regions higher above sea level typically have lower barometric pressures?
Those of you who live at higher elevations, how are the Dyno numbers and ET's looking?
I may be moving to a place that's at around 2400', whereas I'm at 1700 or so right now.
TIA!

I think it is 3% hp loss per 1000ft.

Looking at that chart puts things in perspective, those #'s have to be close.
It's not looking too bad, like 1 tenth difference, maybe 2 in the 1/4. Get some pullies on there and make up for it...

Air is less dense the higher you go up. Will make a little less hp. Not much less. More air + more fuel = more horsepower in most cases.
