I'm at 6300 ft. elevation. So could you calculate it with the elevation difference?? Sorry I should have mentioned that in the beginning. And THANKYOU!!!!

 

Hey Tim,

the way to do this is to figure out what your ambient pressure is (I can tell you exactly how to do this on a Chevy, but dodge... ). One way is to find the barometric pressure from a local weather site (should be close enough at anyrate) and make sure its in kPa. If your pressure is given in bar, that's cool, because 1.00 bar = 100kPa. Where I live (43' above sea level) my ambient pressure is 1.011bar = 101.1kPa. I don't know how to figure it for your altitude though. I did a websearch for Colorado Springs and got 101.2kPa which sounds awfully high..

Once you've got that you just need to convert your psi to kPa by multiplying the psi by 6.895. For example,

6 psi = 6 x 6.895 = 41.37kPa
8 psi = 8 x 6.895 = 55.16kpa

Then you just add that number to your ambient kPa. So for the ambient pressure I found on the net, where ambient is 101.2kpa, 6psi of boost = 142.39kpa and 8psi = 156.18kPa. You should be seeing 18-19* according to your ss on the previous page.

 

Thanks Erik!!
