Cross Ref Chart - vacuum to psi to kpa to bar
Cross Ref Chart - vacuum to psi to kpa to bar kpa still was not intuitive to me yet.
So I made up a chart showing the kpa equivalents for inches of vacuum and pounds of boost, to kpa. These I do know, and anybody with a vacuum/boost gauge will be familiar with those too.
Thought I'd share...
psi = -(vac) * .4192
kpa = psi * 6.895 + 100
bar = kpa / 100
Now those kpa rows in the various tuning tables mean something to me.
Here are the numbers for quick reference.
The spreadsheet is attached as a zip file, if you want to add finer rows.
