Bar to PSI @ Altitude

For all those of us who don't live at sea level I found this!

You see my boost gauge is in Bar so I want to know if there is really a big difference because normally 1 bar is 14.7 psi but where I live @ 6000ft its only 11.9. Is that really true for something as small as turbo boost. I want to run 16lbs of boost! According to the chart that is 1.11 at sea level would that really need to be 1.28 @ 6000ft. The point is if theres not really a difference then I'd be running 18.5lbs and I don't wanna blow stuff up you know!

Well it appears that you are running pretty close to 16 psi right now

Not really my peak boost right now is 1.14 which is about 16 at sea level but only like 14 here, that is if the altitude is really that big of a deal!

1 bar is equal to 14.5 psi. not 14.7.

ok its roughly 17 psi then, turn it down so you hit exactly 1 bar at full boost and you should be right around 16 psi corrected for your sea level.

The point I'm getting at is does the altitude really make a difference on the boost or not. Cause I want to run 15-16lbs and not make altitude corrections if they don't matter and then I end up running 20lbs. You know!
